WD Red WD20EFRX - hard drive - 2 TB - SATA 6Gb/s 4.8 5 9 9
Good average NAS drive When you don't want to spend too much on higher end, high availibility drives, nor too little on desktop drives, this is a great alternative.Works as expected. Too early to tell reliability on my recent batch. My older batch has been working fine since day 1. March 26, 2015
This product is great I am very happy with this product. I would certainly buy it again. October 29, 2014
So far so good... I've started replacing all of my current NAS HD's w/ WD Red's and to date all continue to run with no issues. September 3, 2014
Good Drives So far to date I haven't had any problems with these drives right out of the box. They've outlasted my hardware I installed them in and enjoyed the performance. July 16, 2014
Excellent Drive for NAS I recently increased the capacity of our RAID 5 NAS system and installed the WD Red drives. They are much faster than the old drives and have worked flawlessly since the upgrade. It's helpful to have the choice of a drive designed for this purpose in the WD Red product line. May 14, 2014
Simple and effective workhorse Solid drive - fast access and not to much heat. We ordered a batch of 12 got one doa. Fast replacement and they have been cracking ever since! December 9, 2013
Great for backing up mutliple drives. Great product. Highly recommend. We use it to backup highly important project documents. June 5, 2013
Solid Server Class Drive After losing several WD green drives in a heavy read/write situation, I switched to the Red drive and have had no problems at all. I have 50+ of these in varying sizes in service. I ordered several from another retailer and 3 came DOA. I've never had that problem from CDW. Every drive has been fine.Yes, the Red server class drives are more expensive, but they are worth the little expense in reliability. June 5, 2013
