Pros: Fast, quiet, excellent value for 2.5" SAS drives

Cons: 1 drive out of 9 failed at exactly 2 months.

Overall Review: We bought 9 drives to create an 8-drive RAID 50 array and keep 1 spare. on the shelf. Setup went great, performance is great, but it's a good thing I bought a spare. My array dropped 1 drive 2 months after purchase. Initiating the WD replacement process.
