There are no issue what so ever. I got the Samsung 830 SSD and it's as fast as the one installed by default by apple on the air/retina.

Ditto the "self" upgrade (even it's not the Samsung).

3rd party 512GB SSD's are starting to get reasonable (e.g., Crucial's M4). Plus, this might be the last MBP13 one can actually get inside to upgrade. :(
 
I'd guess their demo unit had a SATA II HDD in it, hence the negotiated 3Gbps speed. I doubt they put a SATA III HDD or SSD in it to test as they don't mention doing so.

Considering the 2011 models supported SATA III drives, I can't imagine the 2012 wouldn't.

EDIT: Also, due to the bottleneck being the HDD, a SATA II vs SATA III model HDD doesn't make much of a difference which is why they probably shipped it with one. As the 2012 MBA has a SATA III SSD, I would assume the MBP SSDs are also SATA III from the factory. But it would be cheaper to just buy your own.
 
so you are getting full SATA 3 transfer speeds?

Yes, I'm getting the similar speeds to what others are getting in their 2012 Macbook Air.

awesome thanks for the replies i can order mine now.....as regards to the RAM will it make a difference that the Corsair Vengence is 1.5 volts as opposed to the 1.35 volts specified the specs for the mid 2012 MBP's?

thanks
