2011 MacBook Pro - SATA 6 Gigabit Link Speed

[lloyd709]

If your optical bay reports 6G capability then your SATA 3 SSD likely will not work at all, not even at SATA 2 speed. It isn't worth trying it. I bought an MBP with 6G optical bay just to test the theory and had to return it. My early 2011 MBP with 3G optical bay however happily runs a SATA 3 SSD at SATA 2 speed.

I think I read somewhere (in agreement with what you are saying) that the Feb Macbook Pros are will run SATA 3 SSD at SATA 2 speed but not the newer versions. Does anyone know how much truth is in this? I'm sure I also read somewhere that there is a disadvantage with the Feb version (to do with the performance of the optical bay connection) but I can't remember what!

Also, are there any thoughts on whether Snow Leopard will be fine?

(sorry for all the 'I read somehwere' but I've researched this before and tried to find the information again but can't)

Dear friends, I own a MBP 13" 2011 and my experience is: I bought 2xOCZ Agility 3 240GB and replica optibay from Ebay. Well fist I tried to make a RAID0 under Mountain Lion and it couldn't be achieved. I discovered that the transfer rate on both SSD was 6Gb/s and with the OCZ Tool I had to fix it to 3GB/s. Then I could make the RAID0 and worked fine. I wasn't happy and I reset the transfer rate of one of them (placed in the main port, not in the superdrive port) to 6Gb/s and the other keept on 3GB/s (placed in the superdrive port) made the RAID0 and worked. Still unhappy! Because I saw that both ports are 6GB/s capables. I think the replica caddy optibay I bought in eBay is the problem... Someone agree?
