Product Reviews
Rated 3.8 out of 5 by 8reviewers.
Rated 5 out of 5 by It spins it stores data Based on Backblases stats this is one of the more reliable 3Tb drives out there. Not the fastest but the more reliable. For a home or SMB NAS array this is perfect. January 27, 2016
Rated 4 out of 5 by Very Reliable Hard Drives For use in a very active NAS this drive has good speed and reliability September 16, 2015
Rated 5 out of 5 by great hard drive for NAS I've been using the drives exclusively for all my NAS applications over the last couple of years and have yet to have any problems at all. Of course, they are just hard drives and some will no doubt fail eventually, but so far I haven't had a spot of trouble with them.This is FAR more than I could say about the Seagate HD's that came with Iomega NAS units, but that's another story for another product. June 3, 2015
Rated 5 out of 5 by Excellent value I had a drive failure in a Netgear ReadyNAS unit that had 4 2-GB drives. For the price, I decided to replace all 4 drives with these 3-GB units and keep the good 2-GB drives as backups for the two other ReadyNAS units I have. Obviously I had to copy all the data off the old drives and copy back onto the new ones after initialization but it was well worth the effort. June 3, 2015
Rated 5 out of 5 by Great for NAS or backup Plug and Play designed for NAS or Backup system. Thanks! January 21, 2015
Rated 1 out of 5 by This wasn't a good fit for what I need This wasn't the best decision to get the WD Red HDs. Had all kind of problems getting these to be a bootable. I got these since we plan on getting a NAS system and I thought of getting HDs suited for them but it wasn't a good fit for an older Mac and older version of server, Tried creating a RAID and it would not install OS, tried no RAID and it would not boot. Finally use it as a data HD and had another older HD as a boot drive. The WD Red are a lot slower. I wished I bought a WD Black but I have to deal with it. My advice to anyone who wants to put the WD Red into an older Mac, to consider NOT using them July 2, 2014
Rated 1 out of 5 by Failed This drive failed within 1 week of use. I was very disappointed as this was the 3rd one to fail in less than 3 months. February 6, 2014
Rated 4 out of 5 by Good Hard Drive Its a hard drive, it worked....no problems. reliable. December 11, 2013
