My specs on my current PC are below in my signature, and I feel it's time to make the leap to SATA. My motherboard only supports speeds for SATA up to 150 MB/S, but newer SATA drives are faster. Will buying a SATA drive faster than the allowable speed rating on my mobo cause problems? I'll eventually pull out this dinosaur of a motherboard, so I want something that will upgrade itself once I upgrade the mobo.
