Bad sectors everywhere

Brett H., Newegg
23 April 2015
  • Summary: I wouldn't buy these. Western Digital warranty support is painful, and I don't like that I need to pay shipping to get my defective hardware replaced.
  • Pros: 4TB
  • Cons: 2/4 drives had bad sectors in three days.

Works, but one DOA?

JAMIE W., Newegg
14 April 2015
  • Summary: Honestly, compare prices. For a NAS, the Red's had been good for us and lasted years without problems. We chose this drive for the comparable pricing, long warranty, and the construction/vibration technology for our site.
  • Pros: Using five 4TB's inside Synology DS1513+ in RAID 6 for business use. My performance has been good so far. After over 2333 hours of usage, still no errors reported through extended SMART tests. Tested: Two USB and one ethernet simultaneous file reads and writes. The NAS is performing at over 200 M...
  • Cons: Received one DOA. Also, we had to pay to ship the drive to WD. However, it was replaced, which took about 10 days time. Honestly, this is the first DOA I've ever received (and I've been ordering drives for many years). All drives were packed together, so it have been something with that particula...

Enterprise only if you can't divide by 10

Pascal M., Newegg
11 March 2015
  • Pros: cheap for an enterprise drive, which it's not
  • Cons: Specifications state 10 in 10^15 URE. That's 1 in 10^14, so it's really a consumer-level drive, not an enterprise drive, which are recognizable with UREs of 1 in 10^15 or better. Are they targetting the math illiterate?

2nd set of drives...in a good way.

MrPeabody, B&H Photo
10 February 2015
  • Excerpt: I have used these drives in a 32 TB Synology NAS for over 2 years and have absolutely no problems. I bought another Synology NAS as we needed more storage space for our HD video files. My first Synology NAS utilizing these drives provided me the confidence to purchase a second NAS.
  • Pros: Durable, Fast Connectivity, Quiet, Reliable, Versatile

Chris McLean, Amazon
29 December 2014
  • Summary: We ordered 45 of these to populate a NAS and 5 were not 4TB drives. 4 weren't even WD drives, but were Seagate 500gb drives! All were labeled as 4TB Western Digital drives!
