[citation][nom]VioMeTriX[/nom]as far as i understand these use similair technology to usb flash drives with a hard drive interface.... the flash technology is super cheap, so why so exspensive for a solid state drive... and if they replace regular hard drives too fast, no one will be able to afford a computer[/citation]
Because to reach speeds like this you need many smaller flash chips (working in parallel) while in a USB drive, one big chip is enough.
