Crucial MX300 525GB SATA 2.5 Inch Internal Solid State Drive - CT525MX300SSD1

It's my first SSD, so I am naturally impressed with the considerable improvement in boot up time and the neat, compact nature of the drive. It was easy to install in my tower (with a separately purchased 3.5" drive bay bracket and cables; the '9.5mm Adapter' that comes with this SSD is merely a hollow rectangular frame that sits underneath the SSD, I think it is only useful for laptops and I didn't use it), and the Acronis software key provided allowed me to download and use Acronis to simply transfer the contents of my hard disk drive. This transfer process took, if I remember rightly, between 30 and 40 minutes (you click through a few screens, making sure correct disks are being copied from and to, then leave it to do its thing for the vast majority of this time). I advise looking at a few videos on Youtube for instruction on physically fitting the SSD and preparing it with the software (Crucial have some of their own videos on Youtube, and videos by other SSD manufacturers and members of the public could be helpful too). Note that this SSD (and all the other ones I browsed) doesn't come with a 3.5" bracket to fit in a standard desktop drive bay, nor does it come with any cables to connect it to the power supply and motherboard. You will have to buy these items separately unless you have them already (if you keep boxes after buying a new PC, with manuals and original discs etc, check them; there are often spare cables), but they are cheap and available from lots of online retailers. As I mentioned at the start, my PC boots up faster now. It reaches the desktop screen quicker, and once there, there is no extra loading- on my HDD I would often be waiting about twenty seconds for anything to become responsive as it was still loading startup programs. I've noticed a few games load up faster too, which is nice. This performs well, no problems encountered, and at a good price. I needed a little more than 240/250 GB capacity which are the norm at this end of the scale, but didn't want to go up to 480/500GB prices.

I’ve been a big fan of Samsung drives, but the price difference on the 1TB was enough to make me jump ship to Crucial. I use it in a gaming laptop as my data drive (I have a 250GB system drive and then the Crucial 1TB for data, games and applications). The laptop is a recent (2017) MSI Apache 17”. It has space for one PCIe SSD and one standard SATA 3. I chose to go with a standard SATA because I’m lazy and didn’t want to mess about with moving the system disk. Anyway, all good, and decent for a SSD (but not outstanding figures) in CrystalDiskMark. That is until I downloaded Crucial Storage Executive and enabled momentum cache. The figures speak for themselves (see my screenshot of CrystalDiskMark). I've also added a second image from Task Manager showing how momentum cache works. The G drive is a traditional HDD transferring 25GB of data to F, a 1TB SSD with momentum enabled (I'm actually installing the game Fallout 4 from G to F). You can see that the SSD only occasionally writes data (about once every 10s). So, a very good thing about Momentum cache is the way it handles small files; it caches them to memory and only writes them to the physical SSD occasionally. This not only saves wear on your SSD, but it also makes certain tasks fly. I am a web application developer, and my build process (which involves working with literally thousands of javascript files) is now super fast (it would be even faster if node/npm was multi-threaded, but that's another story!). What are the downsides of doing this? Momentum cache uses your PC memory as a read/write cache, so you need to have a decent amount of memory. My laptop has 16GB, so all good there. I suspect it will work less well for 4GB systems, or if you are using a power-hungry application (such as Adobe Premiere, which I use). It also increases the CPU overhead. EDIT: I're realised Windows 10 Task Manager > Memory shows you the RAM cache (its marked as 'memory that has to be saved to disk before it can be used for something else' or words to that effect). I copied over the full install folder of Fallout 4 plus DLCs (29.6GB) onto a Momemtum enabled drive and the cache varied between 1 and 1.5GB. So the 4GB is never reached; more like >2GB. Crucial strongly recommend a battery backup if you use momentum cache (i.e. you can lose the cached data on a power fail), so other things equal you should only really enable it on a laptop. The cache is written to the real SSD on power off, so system shutdown takes longer (by 5-10s, so significant). But yeah, just look at those figures; well recommended for laptops with memory to spare; your system flies! Edit: Another good thing about the Crucial I'm finding is that it uses devSleep much more often than other SSDs. Since writing this review (5 months), the up-time for my SSD (according to CrystalDiskInfo) is only 9 hours when the physical up-time has been office hours (8.5 hours a day, 5 days a week). The low up-time saves both power and wear and tear, with no noticeable affect on access time. DevSleep only seems to kick in on laptops (it does not seem to affect my desktop), but is certainly something that will extend your laptop battery life (especially if you have two drives) and the life of the SSDs themselves. Oh, I also suspect the up-time is coming out so low because of Momentum Cache (RAM caching means less access requests to the SSD and more devSleep down-time), so devSleep and Momentum cache probably work together).

Bought the 750GB drive during the Amazon Superdeals for £109 to replace a pair of 500gb RAID1 drives in my main PC rig. The drive was to be used to store all my Steam Games - essentially a games drive. Whilst no slouch, my 500GB RAID1 drives were giving me around 250MB/s and load times for my games was ok. However, with some of the newer games coming in at around 40-50GB in size my requirements changed. What i needed was: - More space - Faster loading times - Reasonable price At £109 (Amazon Superdeal), 750GB, and stated specs of 530MB/s Read and 510MB/s Write this SSD drive certainly ticked all the boxes for me. So lets get the important stuff out of the way first: What is it? It's an SSD drive that comes in a 2.5" form factor, Rated specs of 530MB/s Read and 510MB/s Write and power consumption of around 4mW. This uses the new Micron 384Gbit 3D NAND flash memory similar to what Samsung introduced a while ago with the 850 pro Formatted with NTFS leaves you with around 698GB of useable space. Interface? It uses the standard SATA interface and should work with 3Gbps/6Gbps controllers on most motherboards. How did it perform? Good. Although not top tier and does not quite compete with the best (and more expensive) drives. But then again, this drive is aimed more at mainstream user rather than the extreme or enthusiast users. In terms of my own benchmarks ATTO gave readings at around 500MB's READ and 490MB's Write which is a little below stated Crucial specs. YMMV however. As of writing the current firmware is M0CR011 and there are no updates from Crucial. Load times for games has improved, and with some the loading screen is hardly noticeable - result! Also i've noticed that the temps in my Case has dropped a few degrees - no doubt due to me removing two large 3.5" mechanical drives. Conclusion: Good capacity drive at a reasonable price. Performance is good without being outstanding and I'm hoping this will improve with firmware updates. Reliability remains to be seen but so far (6 weeks) no issues. Overall i'm happy with this drive and can recommend - You even get a code for Acronis to download and use if you need to clone or image a drive!

Hi! I bought this for my Mac Mini i7 [late 2012] 16GB on El Capitan as the original HD drive was crawling. I'd originally replaced this HD with an OCZ 480GB in 2015. Sadly, this device failed after 3 months. Worse, the Time Machine backup had failed. The 'backup' consisted of empty[!] folders for that date. On Cyber Tuesday 2016, I noticed Amazon offering this Crucial SSD for around half price - I bought it! Prompt delivery. I located and used the now well hidden Disc Utility 'clone function' via the 'Recover' menu with the SSD in an external caddy.. To check the drive I selected it as the temporary Boot Drive in 'System Preferences'. Physical installation was easier than with the OCZ. Crucial use the same iFixIT.com pages on their site as I'd used for the OCZ. You don't have to remove the internals or even the WiFi connector. Installation was also helped as the Crucial is slightly smaller than the OCZ. This lets the Crucial slip into place. A wee bit of sellotape and/or credit card can be used to retain drive while inserting screws - the fiddly bit. Results [approx] = Boot times - 45 seconds down from 1min 35 secs, Close down = 1min 30 from 2 mins. Performance in apps etc is nothing short of a revelation! USB 3 sticks open in file format immediately even as thumbnails. Office for Mac apps jump open after a short lag. Preview/Gimp/Photoshop editing = immediate. Internet eg YouTube etc - fly open and run smoothly. Only down side is that the drive capacity is a bit small, so I've had to transfer my Media files to an external drive. If you've got an old HD Drive - you need this SSD! Apparently, larger capacity newerSSDs have improved performances due to better data controllers. But for ordinary mortals, this is academic.

The Crucial MX300 Limited Edition 750GB, for me, was pretty good. Prospective customers should read Tom's Hardware's write-up on this disk, where he criticises its performance - largely the controller. Even so, I was prepared to buy it: why? I got an Amazon Prime superdeal on this disk, just below £110. Amazing value for a 750GB SSD. And it was going into an older PC, which didn't have the fastest SATA interface, or the fastest RAM, or the fastest anything. So its performance would be hindered by the older PC architecture, as much as by its controller. Crucial/Micron also offer 2 extra pieces of software: Storage Executive, which monitors the disk (smart parameters) and provides Momentum caching, which gives a big boost to performance (you end up benchmarking your RAM....). I run a dual Windows10/Linux system, and initially had problems with my new disk - but it turns out that Windows fastboot and hibernate facilities, leave the drive in an unsafe state! (ie it hasn't cleared down all the caches before shutdown) - nothing at ll to do with Storage Executive, which behaves properly on closing down. The second piece of software: a copy of Acronis Image was less successful. I had some problems with it, but Micron/Crucial support came back to me to help out, very quickly. A last comment: such a large drive is of mixed benefit on an old system which uses MBR disks (on BIOS motherboards) as opposed to the newer GPT disks on UEFI motherboards, because of the limits of 4 partitions on a drive with MBR (unless you create extended partitions). A dual-boot system soon uses up the 4 partitions, leaving no partition for the large filespace. I had to maintain a second drive to overcome this limit, and allow me to partition the large SSD into smaller chunks which could be encrypted under BitLocker, to provide better security of documents etc. So maybe this is more a critique of older PC systems than the MX300. At the moment, it's happily installed as the main Windows drive and filestore(s), and performs well in this role. It's not as fast as the more expensive SSDs that don't use TLC (Triple-Level Cell NAND), but works perfectly quickly for the tasks I give it in my PC. And at that price.....!

I've heard a lot about solid state drives and when this one became available, on a special prime deal, I thought it better to upgrade the hard drive, rather than pay thousands for a new laptop with the same spec. It also didn't help that my hdd was starting to generate lots of problems/errors and was clearly failing, so needed replacing. Anyway, without going into too much detail the package arrived as expected, was in a small and well protected box and came with a licence to download software to help transfer files from the old disk to the new one. There was also a small adapter/spacer that makes sure it fits snuggly in your laptop (it may not be required for all laptops). If you know what you are doing with computers then everything is very simple, the drive fitted into the mounting bracket on my laptop very easily, was screwed into place and fired up. I didn't use the software as my laptop had died by then, so I did a fresh installation of everything and all went well. I'd heard a lot about how much quicker SSD's were than conventional drives but I can honestly say that the improvement it's made is amazing. Windows boots just a second or two after turning the laptop on and all the apps I use load quicker and work so much better. File transferring is so much faster and even browsing the Internet is quicker and smoother, with sites that used to lag a bit now loading pretty much instantly. If you've got problems with your laptop, whether it's likely the hard disk is on its way out or even its just running slow, then I would seriously consider getting one of these over buying a new laptop, especially if you've got a half decent processor and/or a decent amount of RAM. If you're someone who uses your computer a lot and have considered upgrading anyway then definitely get one, it's been an amazing upgrade!

Great product at a decent price.

Purchased this the other day when it was in the Cyber Monday sale for a bargain price of just £80.00!! Delivered next day and was able to clone my original HDD in just 1hr 37 minutes! Clearly the writing speed is pretty decent! It does not come with a mounting bracket or cloning software but you can get a bracket for £4.00 on Amazon and just use the free Macrium cloning software (see link below). Probably would have been nice to throw-in a cheap SATA cable too but after only paying £80.00... I can't really complain. Once the cloning is all done you immediately feel the booting and loading time reductions. For example, with all the mods and assets available for City Skylines, it was taking me around 10/15 minutes to load a saved game. That time is now reduced to about 4 or 5 minutes now! So for any gamers out there, I definitely recommend this Crucial SSD! Note: I did experience one issue when playing this game on the new SSD though, it seemed to crash/freeze my PC evertime I closed the application. After some rooting around, I relaised that the "Launch Options" had changed slightly. Whether this was the file transfer or the 8GB RAM boost I also made at the same time is hard to tell though. In summary then. A great product at a fantastic price, one of the best £80 I have ever spent!

Until my purchase of this Crucial MX300 SSD, I only bought Samsung SSDs. I intended to buy a Samsung EVO 850 500GB, but I choked on its $179 price. THEN I saw the Crucial SSD 525GB for $119...and could not resist. So far, the Crucial is a GREAT choice. HERE'S WHY! FASTER THAN SAMSUNG: In comparison to my 'decommissioned' Samsung EVO 850 250GB, the Crucial MX300 is noticeably faster. The Crucial boots up Windows 10 a little faster. Big software, like Photoshop, opens a little faster. There isn't a massive performance difference. Nonetheless, I am very impressed with the very snappy speed of the Crucial. It is the fastest SSD I have owned yet. RELIABILITY: I always bought Samsungs because of their rock-solid reliability. That factor almost caused me to pay $179 for the EVO 850. HOWEVER, I bought Crucial RAM since the 1990s because of its extreme reliability for my custom PC builds . So, I hoped Crucial SSDs are as solid as Crucial RAM. So far, so good...but it is only Day 8...and thus only time will tell. MOMENTUM CACHE: This feature dramatically improves the SSD's 'burst' performance. (I think this feature is why software apps open faster in Crucial than with a Samsung SSD.) PRICE: At $119, the Crucial is a bargain in comparison to Samsungs and Intel SSDs. At $89, it is a screaming steal (which I paid for my 2nd Crucial during an Amazon sale). Definitely 5 Stars for price. SUPERIOR USA-Based TECH SUPPORT: I had a little trouble with setting up the SSD. I thought I got a defective one. I called Crucial Tech Support. A very courteous, knowledgeable technician discovered I overlooked a critical step. My mistake. Thus, the issue was resolved quickly. Afterwards, the SSD worked perfectly. The CON: MEDIOCRE SET-UP UTILITY: Crucial's software utility for setting up the MX300 SSD is a little clunky in comparison to the software offered by Samsung and Intel. Thus, initial set-up is slightly more tricky. In fact, my first attempt failed (but not to worry...just call Crucial Tech Support if you get stuck). CRITICAL ADVICE: You can't just install the Crucial SSD (either as an internal or external drive) and hope it will be immediately recognized by Windows. The SSD will not appear in Windows Explorer (or File Explorer). After connecting the Crucial SSD, you have to open Windows' Disk Management utility and INITIALIZE the SSD. Then it will be recognized and ready for the additional steps below. (If you don't know how to initialize the SSD, call Crucial Tech Support.) CRUCIAL ADDITIONAL STEPS: 1. Download and install Crucial's utility called Crucial Storage Executive. (I installed and used the utility after clean installing Windows 10 and updates on the SSD. You should use the utility before installing apps and other software.) 2. *** VITAL *** Use the utility to UPDATE the SSD's FIRMWARE. My SSD's firmware was out-of-date. 3. Use the utility to OVER-PROVISION the Crucial SSD. Use the recommended setting. (Over-provisioning will extend the life of the SSD at the cost of reducing the usable drive space by about 40 GB. Yes, some geeks say over-provisioning is unnecessary for modern SSDs...but I have a strong feeling that it should be done for the Crucial). 4. Enable the Momentum Cache feature. Perform the steps cited above...and your awesome Crucial SSD is ready to blast off! The VERDICT: If the Crucial MX300 proves to be as durable and reliable as Intels and Samsungs, it is definitely the best quality, fastest 'consumer' SSD for the lowest price. I am betting the Crucial is rock-solid. That's why I bought a second one less than 2 weeks after the first. :-)

È il mio primo SSD, dopo aver letto tanto in merito a questi solid state drive mi sono deciso a comprarne uno. Versione da 275GB per poter installare il S.O. (Win 10 Pro 64 bit) ed i programmi base che necessitano di un caricamento rapido dei dati. Crucial, una delle aziende più attive in questo settore, è nota agli appassionati di tutto il mondo per l’elevata qualità e affidabilità dei suoi prodotti. Nota alla pari di Samsung per gli SSD. Inutile dire quanto la spedizione di Amazon sia stata efficiente. Al contrario dei dischi meccanici il pacco per gli SSD è congruo con le aspettative, non essendo così delicati come gli HDD. Confezione e Bundle: Il design è come molto curato, anche se minimalista, il colore predominante è il bianco. Nella parte frontale, oltre al logo dell’azienda, troviamo un’immagine che raffigura un’anteprima del drive contenuto, la serie di appartenenza e la capacità di archiviazione, in questo caso un insolito 275GB. Girando dal lato opposto la confezione troviamo l’elenco dettagliato del materiale fornito a corredo e alcune indicazioni del produttore tradotte in diverse lingue (manca l’italiano). Dopo aver aperto la confezione notiamo che sia l'SSD sia l’intero bundle fornito con lo solid state drive, sono ben riposti all'interno di un blister di plastica nero rigido. Assieme all'SSD troviamo quindi: 1x Adattatore per l’installazione dell’unità in un vano da 9.5mm di spessore; 1x Cartaceo riportante il seriale per l’attivazione del software di migrazione Acronis True Image HD. Specifiche tecniche: Crucial Serie: MX Serie: Crucial MX300 Fattore di forma: 2.5 “ Controller: Marvell 88SS1074 NAND: Micron 384 Gbit TLC 3D a 32 strati DRAM: 512MB Lettura sequenziale: 530MB / s Scrittura sequenziale: 510MB / s Lettura casuale file 4KB: 92K IOPS Scrittura casuale file 4KB: 83K IOPS Modalità risparmio energetico: 4mW Inattività: 75mW Massima potenza: 5.2W Durata: 220TB Garanzia: Tre anni L’interfaccia di trasmissione è ovviamente conforme allo standard SATA III a 6Gb/s, quindi il massimo ottenibile dall'interfaccia classica SATA. Al fine di garantire una buona solidità, resistenza agli urti e dissipazione del calore generato dalle componenti interne, è stato scelto l’alluminio quale materiale principale di entrambe le facce della scocca, con la parte superiore che si presenta satinata e dalle forme arrotondate. Nella parte posteriore troviamo un’etichetta adesiva riportante il modello preciso del prodotto, con relativi numeri di serie, e un codice a barre bidimensionale (QR Code). Troviamo, inoltre, il codice PSID, indispensabile per poter sbloccare il drive nell'eventualità di smarrimento della chiave di criptazione dei dati contenuti. Questo aspetto non lo ho mai provato. Eseguito un semplice test con l'SSD occupato solo dal sistema operativo, come detto Windows 10 Pro a 64 bit. Il test si riferisce ad una misurazione delle prestazione con file da 1GB, SSD occupato in 20 GB e in uso dal sistema stesso. Dopo averlo utilizzato ormai per 3 mesi posso giungere ad una conclusione: Crucial MX300 è in competizione con i modelli Samsung EVO, quindi parliamo di una categoria intermedia di SSD. Rappresenta il giusto compromesso tra prestazioni velocistiche ed affidabilità nel tempo, senza rinunciare ad un prezzo contenuto (anche se da un po' di tempo il prezzo delle memorie NAND è in aumento, riscontrabile sia negli SSD sia nelle memorie RAM), risultando di fatto la soluzione ideale, per tutti coloro, che intendono abbandonare gli ormai vecchi e limitanti dischi rigidi tradizionali di tipo meccanico in favore di una ben più prestante unità allo stato solido (SSD), capace di donare nuova vita anche a sistemi non proprio al passo coi tempi, come ad esempio vecchi notebook o PC aziendali, pur senza dover affrontare un notevole esborso di denaro.

Bought it for my Lenova Y580 formerly 650 G hard drive. I am not a tech person, so had to watch videos to see how it was done and it was pretty easy to install (if I can do it, anyone can). The result is amazing. It used to take 5 to 10 minutes to restart my computer, which was mainly because I had a almost full, very slow hard drive. I just restarted it now with the new SSD, (my third restart since installing) and timed it at exactly 20 seconds from beginning to shut down and up again to my desktop ready to use. My apps and programs load almost instantly, even Adobe Lightroom and my raw photo files, which used to be the slowest of all my programs and files to load. The rest of my comments here pertain only to a couple of snags I ran into during the cloning process, and have nothing to do with the SSD itself. I did have to get a SATA to USB cable, which I hadn't realized I'd need at first. (I wasn't kidding when I said I know almost nothing about these things). The other problem I ran into is that the Acronis True Image 2015 software wouldn't work. At the reboot point, it would not continue running the process and I had to start it again. I tried a few times (which was time consuming) before I realized it wasn't going to work. I finally figured out that it didn't work on Windows 10. There was a patch available on their website but it didn't work either. Apparently you can only update the patch if you already have the full paid version of it, and that's how I discovered this version that comes with the SSD is just the 30 day trial. ( I am not sure why you need to enter a key or serial number if it's just a trial because you can download that yourself at any time from their website. ) So I tried downloading the 2017 trial version from the Acronis website, and it didn't work because the Cloning part, which is the only part I needed, was only available on the purchased version. I didn't want to spend another $50 for a one time process, so googled for a solution and found another free program called Aomi Backupper. This was very easy to use and although it took a few hours to clone, it worked perfectly. It probably only took that long because of the state of my original hard drive. It created some partition issues (probably because I hadn't known which option to select in the cloning process, so picked "optimal for ssd". ) I had to then download the free Aomi partition program so I could move and then extend partitions it had created in order to have my C drive extended to the extra 300 or so gigs the new drive had from my old one. So, while I have heard how good the Acronis software is, just wanted to let you know if you do get the older version that doesn't work with windows 10 and you don't want to put out more money to buy it, there are other free products out there. Aomi Backupper worked great for me, but I have no idea if it's one of the better ones or not. It was just a lucky first try. So I am giving 5 stars just because the SSD is fantastic and the Acronis issue, wasn't a big deal. I would have bought the hard drive even without it. It was a nice bonus that probably works for a lot of people, and had it worked, I would have been thrilled, but it all turned out fine in the end. Hopefully Crucial will start including a newer version that also allows you to Clone on WIndows 10. But I do love the new hard drive. I also swapped out my ram recently from 6 to 16 gigs and between those two things, I feel like I have a new computer.

My Lenovo W530 with high end processor (i7 vPro) + 16 Gb RAM was giving me hard time. After analyzing what is going on, I figured out that the hard drive was the main bottleneck in terms of performance. I was looking for some great SSD and MX300 Limited Edition 750 Gb SSD was great option at great Black Friday price. And, I am very glad with this SSD. Performance is fantastic and boot time and overall performance has much much improved. I have no complains. This hard drive is engineered with Micron 3D NAND technology which is one of the most advanced technology in industry. I did not had much data on hard drive and I read from other reviews that cloning software may give some hard time. So what I did was, I did fresh install of Windows 10 from bootable USB flash drive. If you upgraded to Windows 10 for free from Windows 7 or Windows 8.1, you'll have a digital license instead of a product key. Digital license is an activation method in Windows 10 that doesn't require you to enter a product key. If you activated a free upgrade to Windows 10 or bought and activated Windows 10 from the Windows Store, you have a digital license for your device. This means you can reinstall the same edition of Windows 10 that your device has a digital license for without entering a product key. During reinstallation, it will ask to enter a product key and you can skip this step (select I don’t have product key). Windows 10 will automatically activate online after the installation is complete. Hence, there is no need to deactivate/release licence before performing fresh install. I liked this method because it allows me to completely removes all the garbage I had collected due to Windows upgrades and other software install. After fresh Windows 10 Pro install, I reinstalled software such as MS office. As far as the data on old hard drive goes, you can always connect your old hard drive through SATA to USB cable or Hard drive enclosure. Remember that first you need to boot PC/laptop before connecting old hard drive because your old hard drive still has Windows installed and if you connect it before booting PC, system may get confused as for where to boot from. I then transferred data from old hard drive to SSD and then formatted the old hard drive. Got $14 hard drive enclosure for old hard drive and that is my additional storage now. DONE. I highly recommend downloading Crucial Storage Executive software which immediately detected firmware version and update the firmware with the latest version without any issue. It is great tool to manage/monitor SSD performance as well .

I decided to purchase this new Crucial MX300 750GB to replace my aging 250GB Samsung 840 EVO as my Windows 10 boot drive in my desktop computer. I have previously used Crucial's 64GB C300 series as well as their 1TB MX200 series SSD's and I always choose them for their performance, reliability, and longevity. Crucial states that this drive should be able to sustain up to 220TB of writes, as it contains Micron's latest 3D NAND technology. It's capable of reaching speeds of up to 530MB/sec read and 510MB/sec write, and I was able to get these speeds with Crystal DiskMark. The screenshot I have attached shows how much more of an improvement you get when you enable Momentum Cache, which is similar to Samsung's RAPID mode. This increases the endurance of the SSD by allowing the DRAM to absorb the random writes, as they tend to wear out the NAND cells faster than sequential writes. Crucial recommends that you only enable momentum cache for the SSD if you are in fact using it as your boot drive. This drive would also be ideal for use in laptops because of it's incredibly low power draw of 0.075W of power. It certainly may extend your laptop's battery life over a traditional 5400rpm or 7200rpm drive, but the difference will likely be subtle. I would say maybe an hour longer? (just guestimating) Still, I am glad to see Crucial finally releasing some software (Crucial Executive Storage Client) to compete with Samsung's excellent Magician software. You must download this from Crucial's website if you wish to enable their Momentum Cache for better performance. It's not quite as much of a standalone program as Magician, as it uses your web browser to configure your drive, but it has all of the most important information you need about your SSD, as well as the ability to easily update your firmware. I used it to update the firmware of my 1TB MX200 since the MX300 was already on its latest, being a brand new SSD at the time of this review. If you are looking for a brand new SSD to replace the hard drive in your laptop, or to use as a Windows boot drive, look no further. The 750GB MX300 gives you a bit more bang for your buck than either a 500GB SSD or a 1TB SSD, so it really hits the sweet spot in price per gigabyte, and it should have no problem lasting you for several years of use. You will likely end up upgrading this drive long before it ever actually wears out. My only complaint is that the Acronis True Image HD 2015 software that comes with this SSD would not allow me to resize my Windows partition from my old 250GB drive when I tried to clone it. I also tried using EaseUs Todo Backup as well as Macrium Reflect to no avail. It was likely due the Windows-created 450MB recovery partition that was positioned directly after my main Windows partition. I ended up doing a fresh install, which was probably for the best, as I originally had Windows 7 on my desktop computer before upgrading to Windows 8, 8.1, and then finally Windows 10.
