Would SATA II 3Gb/s bottleneck a SATA III 6Gb/s SSD???

I am looking into buying a 60Gb-120Gb SSD but I only have a mobo with SATA II ports, but am looking to upgrade in the future. Would buying a SATA III 6Gb/s SSD now mean that it would be bottlenecked by the SATA II ports??

From a strictly technical viewpoint there would be a bit of a performance drop but nothing drastic.

From a real world performance viewpoint you will not notice the slight difference. You would have to run one of the synthetic benchmarks in order to measure small differences.

Get a SATA 3 6Gb/s ssd and be happy! :)

Backing up Johnny's answer.

SATAII does bottleneck a SATAIII drive (that can work to those speeds) but the performance difference compared to a HDD is still massive so its worth it.

I am currently using a SATA 3 SSD on a SATA 2 port. The speed improvements are significantly faster. And no, SATA 2 SSD does not bottleneck an SATA 3 port. It just means that a SATA 2 SSD is not made to SATA 3 levels.
