USB 2.0 acceptable as an Aperture scratch disk?

[Kingsly]

Does USB 2.0 have enough bandwidth to work as an Aperture scratch disk? I know FW is required for video because it supports sustained data streams... but photos don't work that way, right?

Correct. Firewire would make for a faster scratch disk, but USB 2 would still work.

I went ahead and got a G-tech FW 250 GB drive.
