I have a 2010 MBP with 2.53ghz i5. I upgraded the RAM to 8GB on day 1 from OWC. I knew when I purchased it that the 2011 MBP were imminent but needed it in January... I'd like to upgrade to SSD. Previously didn't want to make the move as 512GB SSD was pretty price prohibitive. At $1000 for 512GB aftermarket it now seems to make sense? Should I: (a) just upgrade my HD to SSD on my i5 2.53ghz MBP - if so, is the 6GB/s speed irrelevant for me? I think the motherboard of my MBP doesn't support more than 3GB/s?!? (b) sell the i5 and buy a new 2011 i7 MBP. If I do that, do I buy the SSD from Apple (presumably a 3GB/S?) or buy something aftermarket? I know Apple is a premium but I read somewhere that Lion might not support TRIM for anything other than "Apple" drives?!? I know I can save some money by sticking with the 2010 MBP i5 and purchasing the aftermarket SSD, but the question is, in terms of performance, what about the Sandy Bridge i7? Thanks for your views!
