Summary: Hard drive is great for server use, but watch carefully when ordering from multiple places, the same drive "RE-4 2 TB..." comes in several variations, not all compatible with each other for raid.
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.

Summary: Basic Summary: I have 2 of these hard drive in a mirrored raid that have been running 24/7 for the past 3 years with no issues at all on our servers. These drives were constantly stressed were used as a regular backup service/ repository for large amounts of client data, storing/ mounting of images,...
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: These drives have performed flawlessly in a NetGear ReadyNAS Pro. It is necessary for the NAS's firmware to disable the 'green' function of these drives to prevent repetitive head parking (Load Cycle Count).
