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: I bought this drive for a new Windows 7 install. It is deathly slow. Fortunately I had a spare Seagate 7200 RPM drive lying around which works great. The green is quiet, I'll give it that, but no hope for the performance. It might be OK for storage, but it's useless as a boot drive. My advice would be to buy a WD Blue or Seagate 7200 RPM drive. Don't waste money on this piece of junk!
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!
