I'm in the market to replace my current Mac's hard-drive with SSD, and then also, remove the SuperDrive and throw in a 2nd SSD in the Optical Bay.. I need to know if I should be purchasing a 3G or 6G SSD to place into my Optical Drive Bay?

I have attached some screenshots from my System Information in About My Mac..

so..

Is my optical drive supported for 3G or 6G SSD? Called apple, asked if they could tell me what's inside the machine they built me, got elevated to a manager, who gave me an attitude and told me that's not something they would know.. how does a company.. like apple.. build a laptop.. and not be able to tell their consumers what's even inside the **** thing!?

sorry for the rant. frustration. lol

The link speed is the fastest speed at can be handled on that connection, In this case 6 Gigabit for both devices. The negotiated speed is the fastest speed that the connected devices are currently handling. Other hardware gurus will chime in I'm sure but it looks like both connections could handle 6Gb SSDs.

If you find that you can save some money by getting a 3 Gb SSD for the second drive that should still move along at a pretty good clip. I'm betting that about the only time you would notice a difference is when copying files from one drive to the other.

The primary drive slot in your MacBook Pro is SATA and can handle the higher speed SSD, however, the optical drive slot is ATA and can not. Personally, I would not place an SSD in the optical drive slot but that's up to you. I would just move the spinning hard drive to the optical slot and use it as extra storage space. That will save you some money which you can use to buy a larger SSD for the main drive slot.

I did put an SSD in the optical drive slot and it's amazingly fast. But I did it because for some technical reasons I needed two for a short period of time and so I had a "spare" SSD. It IS faster than a spinner in that slot. I'm not sure I would BUY an SSD just to put in that slot, however, as the increased speed is nice but not required for normal functions. I only really notice when I'm doing large copy/move operations.
