Re: [OM] Image Storage on the Road

[Daniel Sepke]

Expresscard has two interfaces, one that accesses the PCIe bus and one that
duplicates a USB 2 connection. As I understand it most Expresscard devices
currently available hook into the USB connection as the device doesn't a
faster connection most of the time (think wireless broadband devices, etc.).


Memory cards on the other hand are available in both flavors. The Sony EX
camera that I use at work runs on the PCIe versions as it needs big
bandwidth to store HD video. That camera will only run on the Sandisk and
Sony cards that have PCIe. The straight up memory storage cards chips are
not fast enough either. The SxS cards cost about 5 times as much as the
memory only ones (the 16Gb card I got last year was $700).

If it's truly an Express connection it should be attached to the I/O bus.
