Summary: This was a replacement drive for the one that went bad. Always been pleased with Western Digital and its service. The price was very affordable and installation was a breeze being a SATA Drive. Resolved my computer problem....up and running in no time. Very pleased with my purchase and delivery time in shipping and would recommend this to someone needing a replacement hard drive. Thank you Amazon for the great service.
Summary: I am using this drive with my actual W5000AADS in a RAID 1 array. The 2 put together perform pretty good for being the WD Green Drives. The only reason I gave 3 stars is because they sent me the WD5000AACS. I don't know if all Green drives are like this, but both of mine do it: when they start up, they make a strange but quick buzzing noise.
Summary: We needed a replacement drive similar for a server with RAID and got this WD. Worked great, not a dud, and OEM packaging was sufficient. Thanks Amazon for getting it here so quick! Saved the day!
