Summary: I purchased a pair of these to create a RAID-1 array on my Dell Precision 390 since I need relatively fail-proof data storage. It has been several months now that they have been in operation without a problem.
Summary: These drives are used in Cisco MCS Servers. There is a firmware bug in the drives for version lower than B06. Corruption. Major failure. Lots of crying. See attached: "Hard drives with model number WD2502ABYS and any firmware lower than 3B06 are affected - they should be upgraded as soon as possible." [...
Summary: I returned it because it was sold as new but when I tried to register it with Western Digital to validate the warranty they said it had no warranty. It was to old. I contacted the seller and arranged a full money back refund. I returned the item to the seller. When you sell items as new they should have a valid manufacture warranty and if they don't they shouldn't be able to sell them as new because they aren't. They might qualify for antique status but not new.
Summary: I've always used Western Digital and only once had a problem, that was quickly taken care of with the Warenty. This was an Exceptional buy because of the Price. Would highly recommend this to anyone not needing mass Storage!
