Is there any sense to using a USB 2 flashdrive for a scratchdisk? Prices are falling and a 4 Gb is around $80?

Or would this be much slower than a dedicated HD?

I use a separate HD now, but my scratch files hardly ever get larger than
1.5 to 2 Gb.

Thanks,

Bill,

No. That is not a good idea. PS would be considerably slower.

PS treats the scratch volume as RAM, and the physical RAM as a cache for it.

So anything other than IDE bus driven or SATA drives are a no-no.

How about SCSI?

SCSI is fine. You want to use the fastest possible drive for the scratch drive. That may well be SCSI, or SATA, but is definitely not a USB flash drive.

why not make a raid 0 of two fast disk, be it two raptors or two 15k SCSI disks now that would make for a fast scratch disk,
I will try with my HP MSA (mass storage array) with 14 SCSI disks as a RAID 0 and if it makes a difference

What is that Henrik….14 disks allocated at one disk per layer in an image? 😉
