[Barry Green] “The ExpressCard technology allows for 2.5gbps transfer rate at the bus level, but the actual SxS cards are limited to 800mbps. Just like the PCMCIA bus is capable of 1 gbps data transfer rate, but the P2 cards max out at 640mbps.
A faster theoretical bus speed doesn’t translate into real-world performance gains (I mean, the PCMCIA bus is faster than the SxS cards). The underlying memory technology is the hangup; Panasonic RAIDS together SD cards, Sony probably RAIDS together the raw components, but either way there is no memory chip that runs at 800mbps or 640mbps; it has to be done by RAIDing.”
Yes, I see my mistake now – I agree, they must also be implementing a raid chip on their cards. The larger physical size of the P2 cards would seem to hold the advantage for larger future capacity. Yes?
