## Description

Compatible with: PC; Mac

Review: Great HDD for 24/7 Operation! - Pros: Performance. This is the best-performing mechanical drive I have ever tested. I have four other mechanical HDDs dating back to 2005, including three other Western Digital drives, and this is the best performer across the board. It even beats my old SSD in terms of sequential writes and random writes (likely due to the on-demand nature of TRIM in the SSD): Western Digital WD1003FZEX: 1000 GB, 7200 RPM, this review 187.01 MB/s sequential read 184.54 MB/s sequential write 60.89 MB/s random read 109.23 MB/s random write Seagate ST3000DM001: 3000 GB, 7200 RPM, purchased 2012 181.42 MB/s sequential read 178.97 MB/s sequential write 50.22 MB/s random read 90.35 MB/s random write Western Digital WD20EARS: 2000 GB, 5400 RPM, purchased 2011 112.32 MB/s sequential read 107.88 MB/s sequential write 31.34 MB/s random read 56.34 MB/s random write Western Digital WD3200AAKS: 320 GB, 7200 RPM, purchased 2007 76.86 MB/s sequential read 75.57 MB/s sequential write 33.68 MB/s random read 43.90 MB/s random write Western Digital WD2500KS: 250 GB, 7200 RPM, purchased 2005 63.55 MB/s sequential read 62.52 MB/s sequential write 31.32 MB/s random read 38.16 MB/s random write Intel SSDSA2M080G2GC: 80 GB, purchased 2009 253.07 MB/s sequential read 81.98 MB/s sequential write 196.70 MB/s random read 39.61 MB/s random write Noise. This drive is very quiet. I don’t have any empirical data for noise, but the hard drive activity never became audible above the hum of the CPU fan in my desktop. Heat. This drive is very cool for such a high-performing 7200 RPM drive. Even after a 100 GB transfer that took around 20 minutes, reported temperatures never exceeded 30°C (86°F). Weight. Not that it matters much with internal drives, but this is a very light drive compared to my other 3.5 inch HDDs. The area below the platters on the bottom of the drive is recessed about 3/16 of an inch further than other drives, I assume because it uses one fewer platter. As a result, it feels much lighter. Cons: Price. A 5400 RPM Western Digital Green drive with twice the capacity is available for about the same amount of money. However, using the less-expensive green drives would incur a notable performance decrease. In my testing above, this drive had 66% better transfer rates than a 2-year-old 2TB WD Green for sequential reads and writes and 93% better transfer rates for random reads and writes. So for enterprise tasks, one could argue that the performance of this drive merits the increased cost. For most consumer uses, the 5400 RPM Western Digital Green drives are a better value because they offer at least double the capacity for the same price. The performance loss is not significant considering that they outperform 7200 RPM drives from just a few years earlier. However, for technical or enterprise purposes, the additional throughput can be a real benefit. As someone with I/O-intensive workloads (geographic information systems), this drive offers adequate capacity with exceptional performance. All performance tests were conducted using CrystalDiskMark 3.0.3 x64 with each drive loaded into the same SATA hot swap bay. Testing was conducted in Windows 7 Ultimate x64 with a socket LGA1156 Intel Lynnfield 860 CPU at 2.8 GHz, 8 GB of RAM, and the Intel P55 3 GB/s SATA controller on the Gigabyte GA-P55-UD4P motherboard.
Review: Performs great, will buy again. - This drive has been in service for over a year and a half with 3 cameras feeding to it 24/7. One 1080p, one 960p and one 480p camera all 25-30fps. The drive has performed beautifully and is very steady in write performance and temperature (used in a Mac Pro). Loading video, specially while recordings are going, may take a little longer depending on drive activity and file size. For a 5GB 1 hour clip I'm waiting maybe 5 seconds for the file to open and another 5 for playback to be smooth. Slower than you'd see on a traditional drive, keeping in mind this is a 5400rpm drive, but still well worth it. With my configuration it holds a little over two weeks of recordings for all cameras. The drive currently has 15,375 hours on it and the S.M.A.R.T. status and overall drive health is 100%. Not a single bad sector or any signs of wear. I'll replace this down the road only because I'll need a bigger one and even then this will sit in a RAID until it fails. =================== Update, April 2023. The drive just started failing after 8 years of pretty much 24/7 use (69K+ hours on it), supporting 6 HD cameras for the last 5 years. For $70 this was the best money I have ever spent on a hard drive. Ordering a 4TB newer model now, I hope it serves me equally well. These 2TB (WD20PURX), while now an older model, I highly recommend.

## Questions & Answers

**Q: Is it good for primari drive and OS installation?**
A: Hi Alexander, the Purple Series was developed to be turned on 24/7 and are very reliable. As it was developed to arquive files the need to be available all the time it spin at just 5400 rpm. Way too slow for the big systems available today. It,s ideal to put a 7200rpm disk or even a SSD to boot. In my computer I have a 256GB SSD disk to boot and the main programs and two  2TB 7200rpm drives to other files. So I don´t think the purple drive is good to use as a boot disk.

**Q: Will this drive go into my q-see surveillance system model qt5682 which has a 1tb and i'm wanting to upgrade to a 2tb drive.**
A: Yes, yes it will. I have a 3TB drive of this series in my qsee system (QC448) for over  1 1/2 years now running 24/7 and not one hickup so far. These are the best drives for surveillance but not excluded other purposes (in my case file server)

**Q: Can you replace a 2.0 with a 4.0?**
A: Yes, most DVRs and NVRs support 2TB hard drive and larger.

**Q: Is this compatible with a hikvision nvr?**
A: Yes, it work with anr DVR that support sata hd
