Faster than USB?
Can anyone explain how that works? Surely there's a bottleneck on speeds at the PC/ card end?
Buffalo Technology has launched two new external hard drives, with storage capacities ranging up to 1 Terabyte. The MiniStation and DriveStation models also include a USB Turbo feature to help boost data transfer rates. The MiniStation model is available in capacities of 80, 120, 160 and 250GB, while the DriveStation offers …

There are two typical ways to do that sort of thing. One is to compress the data as it goes out to the drive, ensuring hours of merriment when things go wrong in return for never knowing quite how big the disk is, effectively. It also further increases the CPU load associated with your USB devices, as if that wasn't already a problem.
The other is to violate some part of the spec. USB has rules about the priority of various sorts fo traffic, with "bulk", as usually used for storage devices, falling into the "whatever's left" slot of bandwidth. If a device claimed to be, say, a display or audio port, and used the isochronous slots, it could dial up the bandwidth pretty much as far as it wanted, killing the response of anything else on that controller. isochronous is not guaranteed delivery, but again, two choices, you could layer either forward error correction or a retry scheme on top, or you could just accept the occasional silently failing transfer, with resulting file corruption.
Any of these choices mean you need a "special" driver that hooks into the OS in "special" ways, so you would be very OS-specific (probably even OS-version specific). Note how carefully they say "Windows or Mac", then "Any PC". If they really mean the former, they don't mean the latter, and vice versa.
