Newegg has the OCZ Solid 3 Series SLD3-25SAT3-120G 2.5" 120GB SATA III MLC Internal Solid State Disk for $100 with free shipping. Features sequential access read speeds of up to 500MB/s and write speeds of up to 450MB/s. SSDs might not be getting bigger, but they're getting way faster.
keep in mind that you wont get the top speeds if you only have SATA II
but won't you get a very fast speed anyway?
Yeah, just not the 500/450 max they state.
