true, but they excel in swap-file situations. I recently saw this in action. I
have some rendering machines which have the same RAM and CPU, but some have
just a standard 500mb IDE drive, others have 2.1gb fast and wide Seagate
Barracuda's with an Adaptec 2940 wide controller. Yet another machine had 192mb
RAM and had no swap. Here are some frame times:
IDE drive, 128Mb RAM, 80Mb swap file 1 hr 15 mins
Scsi F/Wide, 128Mb RAM, 80Mb swap file 15 mins
Scsi F/Wide, 196Mb RAM, no swap file 7 mins
Kind of shows you, if you are going to get a swap file situation (and we all do
sooner or later) then it pays to have a fast disk sub-system. The above results
show me that the systems with the IDE become practically useless with even a
smallish swap file, while the SCSI fast/wide ones are still somewhat useful.
