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: Purchased 4 of these hard drives in late 2010. After only 3 years and 101 days in a home server, two of these drives are now reporting multiple sector errors. WD diagnostic program confirms the sector errors. Contacted the WD website to discover there is no 5-year warranty concerning these drives.
Pros: Low noise, low heat, good data transfer rate
Summary: Bytes Per Physical Sector: 512 (non-AF) - no alignment needed for any older O/S. HDTune 70-145MBps transfer rate, 9.6ms avg access rate [2-17ms]
Pros: High-MTBF and better burn-in for more confidence about reliability. Five-year warranty.
Cons: Shipping quality is poor from NewEgg NJ. Drive arrived within a ESD-safe bag, wrapped in a half-inch of bubble wrap, in the white OEM box, at the exact bottom of a NewEgg cardboard box and then covered by paper filler. Whereas a suspension system isn't necessary, putting the drive in the center w...
Summary: I considered the WD RED 3TB for the same price as the RE4 2TB, after some research found that RED is slow on random access which is a dealbreaker for my application. This is going to double the storage on the machine and should not sacrifice any of the speed.
Pros: Very good price for a WD RE4 enterprise class drive. No more noisy or hot than expected for something designed to be in a climate-controlled datacenter. I bought two of these to replace an aging 1TB WD Black mirror set in my home server.
Cons: As is my standard practice, while the drives were connected to a test system running the DLGDIAG extended test, I plugged the serial numbers into the warranty checker on WD's website to verify their status. Instead of the expected 5 years, the ones I received are reported as "no warranty." Newegg...
Summary: Long time Newegg and WD fan, never had a failure. I don't see how Newegg can get any cheaper in packing for shipment. Bubble wrap is now down just barely single layer and anything would work better than the wrapping paper stuffed into the box.
Pros: Price finally starting to come down on these.
Cons: Might as well drop them from planes given packaging.
Summary: Out of all of these drives that I've purchased, most are still in operation. I did have one start to die on me a few months back but it gave me plenty of warning that it was failing, and WD's exchange policy was fast and seamless.
Pros: Speed, length of warranty, general reliability in 24/7 operation
Cons: Recently purchased three more drives based on previous success with them. One of them arrived DOA (failed SMART test, failed bad block scan). Replacing through Newegg would take too long, so I crossed my fingers and ordered a fourth, while returning one of the three as defective to Newegg. Would ...
