I'm debating over which SSD Drive to get; Intel 320 or the Intel 510. However, one is for SATA III 6Gbit speeds (510) and the other for SATA II 3Gbit speeds (320). I'm on a Macbook Pro with SATA II and my question is; Will an Intel 320 saturate real world speeds of SATA II in my MBP even though 3Gbit is technically 375mb/s? The 320 is rated at 275mb/s, but if real world SATA II speeds are higher, would I benefit from the Intel 510's 400mb/s speed eventhough its slightly above the 375mb/s theoretical SATA II transfers? Thanks!
