I am building a new system and began to wonder about the limitations that HD's would put on SATA. Basically, I have been thinking about getting a solid state storage device (for boot drive) and wonder if there is any point to going with sata III.

OK, so here is the question: If the read rate is 300 MB/s and write 275 MB/s then would there be any difference between 3.0 GB/s and 6.0 GB/s transfer speeds?

It just seems to me that when reading with both transfer speeds the rate would be 300 MB/s and when writing the buffer would full up in a few microseconds while the drive is writing 275 MB/s.

Any help from someone with more technical knowledge is appreciated.

Thanks,
