6 GB/s SATA vs 3GB/s SATA

I am using an SSD as the system drive for Sage. Does it matter if the SSD is plugged into a 6GB/s SATA port as opposed to a 3GB/s SATA port or are there other issues that will be the bottleneck?

Ultimately, that would depend on the speed of the SSD. Does the SSD use SATA 2.0 or SATA 3.0? While the use of SATA 3.0 doesn't necessarily dictate that it is fast enough to fully saturate the 2.0 standard, it's a data point. But, the real indicator is whether the SSD is actually fast enough to saturate it. If so, then you run the risk of the interface being a bottleneck.

My SSD is a 128GB OCZ Vertex 4. I believe it is SATA III.

Under the right circumstance, that drive certainly has the ability to easily saturate the SATA 2.0 and even comes close to doing that on the SATA 3.0 interfaces. You'll need to check the speeds you're hitting to figure out whether or not you're real world scenario is bumping into the 2.0 limits. If you are, clearly, you would be well served by moving it to a 3.0 interface.

If you have sata III available, then use it. Only if it is on the motherboard. If you were looking to get an add-on card, the good ones are WAY too expensive.

I have a vertex 4 plugged into sata II and it works wonderfully, but would be better in a III port. The only thing you'd ever notice a difference is moving files around, access time and everything else (what makes things faster for the most part) will not change. Sata II is still very fast for that drive.

I never paid any attention to which SATA port I used. The mobo has most of the SATA ports on the edge or the board and it is a bit tricky to plug them in given the way the case is constucted.

I just checked and I think all of the ports on my Mobo actually are SATA III. I think this mobo is an Asus P7H57D-V Evo or something like that. It has a group of 6 SATA ports and 2 additional SATA ports and I think that they are all SATA III so I guess I am good.

The (2) SATA port cluster are SATA III. The (6) port cluster is SATA II. If you have a SATA III port available, as others have mentioned, there is some advantage with the speed of some file operations (usually large files only). The Vertex 4 is a great SSD to exploit SATA III.

The biggest benefit to an SSD is in the vastly improved access times, and the SATA type you use won't have much affect on that. So it's possible running fast drive connected to an SATA II port will handicap it, you'll get 99% of the benefit of using an SSD as a system drive regardless of what type of SATA port it's plugged into.
