stress test?

[nlm9802]

I'm looking for a good free stress test that tests the ability of a set of hard drives to constantly read/write large amounts of data.
I currently have 4 250GB drives spanned as one volume in XP pro for a total of 930GB (12GB overhead per drive) >_<
I would like to test it prior to delivery by bombarding it with data constantly for 12-24 hours. My main concern is the power supply.. it is a 240W HP/Compaq power supply, powering a p4 2.4 (60 watts), 4 250GB (2 IDE, 2 SATA) hard drives (10-12 watts each), 1 IDE 80GB drive (10-12), and an IDE dvdrw/cdrw (? watts).
The spanned volume will be backed up regularly, the main concern is if it can handle being up 24x7 for about a year, with constant use weekdays.

I am no expert in PSUs, but I would get a more powerful one than a 250W to run an important disk setup.
Tom's Hardware has already proved that PSUs quite often do not perform at the level they are rated for. And things can go south real quick if a PSU cannot fail gracefully.
I would get a recognized brand-name PSU at around 450W to be sure. Of course you'll be paying for more power than you need, but that is the whole idea. By getting a PSU that can do much more, you'll be ensuring that it will deliver what you need reliably for a long time, instead of red-lining a lesser one.

But that is just my opinion.

You could use a 100% burn in utility like sisoftsandra but that isn't going to prove much.
I agree with pmonett on this one, you know it's under powered so why try to convince yourself otherwise.
A quality 450watt plus PSU from:

Antec, Enermax, Tagen, Chieftech, FSP, CWT, Sparkle, Zalman, SilentX , Thermaltake etc,etc
Is required.
