Any performance gain by putting Windows Pagefile.sys onto an Software RAID-0 Striped Volume?

"And, would this be hardware based raid or software?

The design that you have ""sketched"" above, really would not have any significant improvements with the RAID... If anything your making your configuration more complex then it needs to be. These are only 320 Gb drives...

Goes into benchmarking a similar setup, and basically burst read has a 50%+ increase, but sustained reading has only a marginal difference... Overall, for the sustained activities only a ~5% difference...

So, does RAID0 really increase disk
performance? Yes, definitely. In our
tests RAID0 doubled the average
transfer rate of our hard disk drive.

How this disk performance increase
reflects on overall system
performance? It will depend on the
kind of application you run: programs
that make a lot of disk access will be
the ones most benefited, of course. On
PCMark05 this increase was between
4.44% and 8.82%, while on SYSmark2004 the best result was on Communication
batch, where we saw a 15.25%
performance increase. On this same
program, Office Productivity
performance was increased up to 6.52%,
while we saw a performance increase up
to 8.52% on 2D Creation batch."
