Summary: great drive and excellent price, at least until you need to return a drive for warranty replacement. turns out the warranty expired 3 years before it was purchased (2/2013). These drives are supposed to carry a 5yr replacement warranty but not in this case.
Summary: First I had problems with one of the drives dropping out of the RAID, then it failed and when I sent it back and got a replacement, the replacement drive was DOA. That makes a 66% failure rate - totally unacceptable.
Just say no to WD - both their drives and their support site are defective

Summary: UPDATE: building a new system, so decided to spend a minimal amount of time getting an RMA for my remaining 2 2TB WD drives. First a reminder: when your drive dies, you don't just lose the hardware, you usually lose all the weeks/months/years of data as well.
Summary: (RE4) are the normal enterprise drives, created for demanding servers/workstation uses as oppose to the home desktop. Timings have been fine tuned for arrays, making them more reliable in the long run hence the price hike. (RE4-GP) is a Green Power, so it's essentially a 5400 rpm disk.
Summary: I have at least 48 of these drives in active use in a large RAID array. We've been experiencing random lockups with our RAID controller for the past few months, and after hours of troubleshooting with multiple players, we've determined that these drives are actually locking up, causing the RAID...
Summary: I tested 10 x RE4-GP drives in a RAID5 and RAID6 array with the following enterprise class RAID controllers: Adaptec 51245, Areca ARC1680ix-16, and LSI 8888ELP with a Chenbro CK12803 port expander. The LSI only has 8 ports and to accommodate 10 drives I needed a port expander.
Faulty new drive and then truly terrible support from WD

Summary: I was untill now a big fan of WD, but that was because I had never needed their customer support before. I ordered a set of WD2002FYPS drives of the current model 02W3B (not from amazon but elsewhere) for use in RAID.
