In my opinion ( yes, we all know I'm very opinionated), that's why I'm so loved - hated. A hard drive in the optical bay is an option of last resort. The BUS is slow. Problems getting it to work, compatibility issues, the cost of the bay adapter. If you need more storage go with a SSHD - better speed, more storage, GB for GB a better value. extends the utility life of the machine, you don't lose functionality of the optical dive.
