I have a 2011 13" MBP with a dual drive setup. Noticed that the optibay drive recently started slowing down on some copy operations. Checked SMART status and start stop count shows as ~200k. The count is increasing rapidly as I'm using the MBP, almost by 1 unit every 3 minutes. Even after I disable the "Put hard disks to sleep when possible" option, the start stop count increments at the same speed. I guess it's time to replace the drive? Could it be because of a bad caddy? I'm using a generic Chinese one.
