Important point to keep in mind. Even though ExpressCard is capable of a theoretical 2.5 gigabits per second (vs. PCMCIA PC Card's 1 gigabit per second) but you have to factor in that even a two-drive RAID of hard disks is only capable of sustaining something like 600 megabytes per second. Firewire 800 will be plenty fast enough.Spec-Comm said:hcThe limiting factor in the transfer data rate is primarily the HDD.
