Overall Review: I bought this drive due to the price and the warranty which I thought was a good buy. After a month linux kernel was reporting read errors to the drive. I pulled the drive and placed it in a separate workstation, using onboard sata, I wanted to verify the controller or cables on the server was not generating the errors. After receiving the same errors I ran a smart test, smart long test threw errors and was not able to finish due to read errors. I thought okay fine western digital should send me a replacement drive, this has been a nightmare, first western digital would not approve an advance rma, second I have shipped my drive to them and they are just sitting on it, not sending any replacement drives. This is a huge issue for anyone using these disks in a NAS, depending on your use case if another drive fails data lost is a real possibility. As it stands western digital is just holding my drive and refuses to issue a replacement.
