SSD in optical bay slot

If you have a chance, could you do me a favour and check system information for the link speed of the optibay?

System information > Serial ATA

Thanks.

Yup, it's running as SATA II (3Gbs)

Just upgraded my 15" Mid-2012 with a 256GB Samgsung 830 in the optical bay. Stock HDD left alone in original HD bay. The SSD shows up as SATA-III and is giving me blazing speeds. Zero beachballing. Trim enabled with Groths. Fresh install of Lion, no migration assistant or restore from Time Machine back-up. Manual file copy for the win.

Prior to doing my upgrade, I had researched and read that the optical bay SATA data cable was susceptible to electrical noise when used at 6GBs speeds. There were some suggestions for shielding the cable with foil, but it seemed pretty unpredictable to rely on for a stable computer. This wasn't an issue as delivered by Apple since the optical SuperDrive wouldn't be affected, and apparently the problem wasn't deemed necessary to fix.

Therefor, I opted to mount my 6G SSD in the original disk location, and put the original 3G disk in the optibay frame replacing the optical drive. I then mounted the removed SuperDrive in a purchased external USB enclosure.

So far ... everything is working fine and I am very pleased.

The success some people are having may simply be luck with a better original cable, or better noise immunity with their particular SSD unit. YMMV

Thanks : )
I think it seems my chipset is completely different, it's NVidia, not Intel

Damn, I wish I could get a 2012 MBP, they've evolved SO MUCH over only 2 years. Check this out- http://www.youtube.com/watch?v=VnxSHpUI8Ss

Thank you. This was amazing, this actually helped the most.

It seems my original HDD will work in the optibay, whereas my SATA III SSD will not. I've purchased a SATA II SSD, that should work in that case, thank you.
