I would suggest you use a completely separate disk then you won't have problems with random seeks stuffing you up. You might want to consider higher performance disks too (although ISTR 10k & 15k RPM disks don't get [much] more sequential throughput). -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
