Pros: When they are working, they seem to be all they're hyped up to be. RMA process is very good, although I wouldn't expect to have to use it on new drives.

Cons: Where do I start.... Ordered 2 of these for a new desktop build and set one drive up as a clone of the other. These were to be used purely as file storage. Right out of the box 1 drive was good and the other had SMART errors. RMA'd the bad drive to Newegg and got the replacement within a week. Fastforward a few weeks and the other original drive started receiving SMART errors. RMA'd that back to WD and got the replacement drive. Guess what... that drive was bad too so back to WD it went.

Overall Review: If I had to do it all over again, I would look elsewhere as to WD. The RMA process for both Newegg and WD was pretty simple and straight forward. To go through 3 bad drives to find 2 good ones seems like the quality control isn't there. I had my operating system running off a SSD and at least had 1 good drive operational while this all took place. The first 2 months of the PC build were rough due to these drives but haven't had any issues for the last 4 months.
