I'm buying a new MBP and thinking about getting SSD as a boot/applications drive. Trying to decide if I should get it from Apple or to get the standard spinning disk and then adding a third SSD to the superdrive slot. Getting the 128GB Apple SSD works out to be about $300 ($200 upgrade + $100 storage drive), where as getting a third party 128Gb SSD is about $200. Can anyone compare the speed of the drives apple supplies vs what's available on the third party market? I know only Apple supplied drives natively support TRIM. How big an issue is this? Are Apple's drives 6GB/s or 3GB/s? How much does the SATA speed affect performance in this situation?
