Review: Neat solution for squeezing a disk in adding SATA 6G support! - I don't normally leave reviews but as this product only really seemed to have reviews stating it was good for Macs, I thought I would help anyone who was in the same boat as me and wanted to know if this works well for Windows PC's too. In my scenario, I have a Supermicro server which has 8x hot swap bays that were all filled with large storage disks in hardware RAID and I wanted a neat solution to add a SSD OS drive but due to the nature of the chassis being geared for hot swap caddies (and all of these were used) it would have involved a number of extenders and splitters plus a disk dangling loose in the chassis which I was not a big fan of. That was until I came across this product which doesn't need any cabling (ie. no SATA data cable going to a header on your motherboard and no SATA power cable going back to your PSU) - everything it needs is handled via the PCI-E lane yet your motherboard still picks the drive up as a normal SATA disk and thus no drivers, OS reinstalls or additional configuration is needed. The other benefit of course is that, if like me, your onboard SATA is only 3G/s, this card will boost you speeds as per the screen shots I added. All in all, a slightly expensive way of adding another disk to a chassis that's already full but if your a neat freak and or if you want to get more speed from your SSD on a legacy motherboard, this is a very good solution!
Review: Excellent for Mac! Rubbish for PC - UPDATE 14/05/2019 So i can confirm that these do in fact work in a PC. I recently put one of these into a PC with a Gigabyte Z390 UD motherboard, wanting to give it another chance despite when trying it in my dads PC and it didnt work. And with the Z390 UD it works flawlessly. So if you have this type of motherboard? I can say it at least works there both as a data storage device, and a boot device! ORIGINAL REVIEW BELOW: =================== I ordered 2 of these. One for me and my Mac Pro (from 2009) and one for my dad and his PC. On my Mac Pro this product works excellently, coupled with a Samsung EVO drive! Boots up in less than 15seconds (MacOS 10.13 + quite a few auto-running applications). However on PC? This thing does not work well. PC detected the card and that there was a drive plugged in however it was never accessible and there were alot of crashes. If attempting to use it as a main boot drive? Everything crashed, stating the boot volume was inaccessible. If trying to use just as a storage device? Crashes, freezing and in some cases totally inaccessible. The drive that was plugged into this was also fine and so not at fault. The requirements for use in a PC are very vague as well. Simply saying 'A PC with a PCIe x2 slot' does not help anyone. Their website wasnt much better either, touting the support for multiple Macs, but again when it came to PC it was a vague 1-2 lines. Nothing of use. In conclusion; Want to use this with a Mac Pro? Go for it! It should work perfectly fine, at least in 2009 Mac Pros so long as you put it in one of the 4x slots. Putting it in a 16x one seems a little wasteful especially when the graphics card is supposed to go there! Not sure which are the 16x and which are the 4x? If you look closely at the Logic Board of a Mac Pro (at least the 2009 ones) the PCIe slots are clearly marked 16x or 4x at the left-side end of the PCIe socket. Want to use this with a PC? Take caution! I dont deny that maybe my dads PC itself was a factor. The BIOS/Firmware on the motherboard does state that it supports PCIe booting, but it just didnt work, even as a storage device. So we had to return my dads one. I'll be keeping mine in my Mac though!

### ⭐⭐⭐⭐⭐ Mind-blowing speed on MacPro 3.1, quick to install, brilliant for Video Work
*by R***1 on 6 December 2015*

Works brilliantly on a MacPro 3.1, running either Mountain Lion or El Capitan. I've paired it with a SanDisk Extreme Pro 480Gb, and am getting real-world 480Mb/Sec WRITE and 530Mb/Sec READ, which is 3.3 times quicker than a 1Tb Velociraptor 10,000rpm HD Drive. Using it with Premiere Pro CC 2015, it means the cache renders are just spectacularly quicker. Best thing of all, for MacPro users anyway -- NO DRIVERS REQD. You can plug it into one of the internal PCIe 4x slots (don't know if it works even faster on the other PCIe 16x not holding the GPU), and with two PCIe 4x slots free (after adding USB 3 card to the third one), it basically means if you buy TWO of these Accelsior S adaptors (plus the SSD to go with each), you can have 6 internal hard drives on a MacPro, and we can all stay up-to-date with the latest tech on an 8 year old machine.
