Im wanting to purchase a samsung 120gb evo ssd but my motherboard only supports sata 2. Does the speeds make huge difference on sata 3?

When I built my current main PC about a year ago, I got 2 SSDs, a Kingston and a SanDisk. Both 128GB.

Did not realize at the time that the SanDisk was only a SATA II drive. Installed the OS and everything. Waaaay faster than a HDD.

Later, I figured out that the SanDisk was only SATA II, and transferred everything over to the Kingston SATA III. In regular ruse, it is faster than the SanDisk, but not by huge amounts.

Bottom line - a SSD through a SATA II interface is still waaaaaay faster than a HDD. But not quite as fast as through a SATA III interface.

It does make a big difference in terms of objective speed, modern SSD's are pushing the limits of SATAIII and SATAII has half the bandwidth of that.
Although what makes an SSD feel faster than a HDD has more to do with its Access Times (essentially non-existent) compared to HDD's (~10ms) than its pure read/write speeds, which isnt limited by bandwidth. You will feel a difference running an SSD, even shackled by SATAII, compared to a HDD no doubt.
