Overall Review: I purchased this drive at the end of October as a spare for my Synology NAS. Unfortunately, I did not install the drive until mid-February, which means that I cannot return it to the seller. Synology reported it as having a Bad Sector Count of 5378 and it failed the S.M.A.R.T. tests. I am returning it to HGST under warranty. Note the that Seller is listed on the order as Platinum Micro in Southern California
