Performance is great in RAID 6 with 16 of these

Black drives have to make it through tighter testing requirements so they should have longer lifespans and better performance than green drives

Their performance to date has been very smooth, although I'm still retaining backups just in case

Performance is excellent and they are not too loud

Quiet and excellent performance.

This drive is relatively new for me, but I expect that it will keep performing as well as it has.
