I have a 13" MacBook Pro that I BTO with the SSD drive from Apple. It came with the "slow" Toshiba SSD. System Profiler reports 3Gb SATA II. I am trying to decide between the Corsair P128 and X128 which after rebates are the same price. What's the catch? The P128 is just a rebadged Samsung so that one is probably a safe bet but the X128 being the same price has me tempted. Is there a reason to choose the P128 over the X128 though? Any compatibility problems with the X128 I should know about? I considered the OCZ models but their forums seem to be flooded with people having problems with them.
