I am attempting to pull even more speed out of what is already a fast
system. I have 3 7200rpm WD 300gb Hard drives installed. If I install
a 15000rpm drive will this improve the overall performance of the
system please? I am asking because this article suggests that partial
stroking a slower drive will bring performance increase.

If this is true what stops me from partial stroking a 15000rpm drive
please? I think partial stroking is his way of saying partition!

Or would a raid configuration be even better please? Raid 5 or 10
maybe so we're getting the redundancy as well as the drives writing
and reading.

A 15000rpm drive would be quicker but MUCH more expensive, and if it's
running in RAID I dare say it'll only run as quick as the slowest
drive. If you're looking for ultimate speed then I suggest some Intel
SSD's, being flash based they're quicker than any hard drive, or
something like this from Micron (6Gbps SATA) -

You would need an SATA controller or motherboard with SATA 6Gbps to
match though with the 6GBps SSD's and they're not cheap.

Just to fill you in a bit. We have a Mac Pro running 2 quad core processors with 8gb ram on a gigabit ethernet. All the Mac Pro currently does is to serve Sage Line 50 files. It is fast - very fast but the boss wants to squeeze more speed. e.g. A Sage search can take up to 12 seconds to process! Ok the real problem is that while waiting for that search other folks are getting locked out and Sage is crashing maybe 2/3 times a day. The real answer is to buy the proper tool. I've been trying to get the client to look at mysql and some front end support and build your own - erp, crm tool. We could then switch to a full Linux system. However, in the meantime we have crashes to deal with.

So the data:

Gets written to a lot

Gets read a lot

Searches crash the computers

Any thoughts on whether speeding up a hard drive would make that much difference please?

Thanks

Rich
