Hi to everyone,

Is it posible to use a usb disk (250Megs) as a scratch disk with photoshop 6?

USB2 will work, but USB 1 is too slow to use as a scratch disk. —

I would imagine even USB 2 would be too slow? Really need firewire if you want to do that, and I’m not sure if there are firewire memory sticks, are there?

I believe that the (lack of) speed of the flash memory itself is the limiting factor. USB 2.0 and FireWire are both fast enough, but flash memory isn’t.

What is the real difference in speed from writing to external RAM–the Flash sticks, or to Virtual Memory–the hard drive? It seems writing to the hard drive isn’t all that fast either. And what about those using external hard drives that are connected by FireWire or USB 2? Anybody doing that successfully?

Other reasons why this is a bad idea include reliability. If the connection is broken for any reason you will likely lose your Photoshop session.

Not to put too fine a point on it, but those forever-quoted USB top speeds are for isochronous pipes, which are not used for data storage and retrieval. Read: it’s way slower.
