[SATLUG] Does my HDD raid setup need improvement?

My current computer set up is:

Hardware
CPU = Intel Q6600 @ 3.2ghz -- idles at 31c
Mobo = EVGA 122-CK-NF68-A1 LGA 775 NVIDIA nForce 680i SLI ATX
Mem = 4gb (4x1) DDR2 800mhz ( pair of CORSAIR XMS2 and PNY XLR8)
GPU = Nvidia 8800 GTS 640mb -- 54c
HDD = Raid 0 -- HITACHI Deskstar 7K1000 750GB 7200 RPM 32MB Cache SATA
3.0Gb/s Hard Drive  -- 29c
HDD  = back up SAMSUNG SpinPoint T Series 500GB 7200 RPM 16MB Cache
SATA 3.0Gb/s Hard Drive -- 21c
CPU Cooler = After market air cooler -- ZEROtherm Nirvana NV120 120mm
Case = Antec Nine Hundred

Software
Dual Boot Winblows Ulimate x64 & Ubuntu 8.04 x64
Ubuntu is the only OS in Raid 0.

When originally installing Windblows, it BSOD with raid(mobo fake
raid), 4 sticks of ram, and GPU driver.   When
installing had to remove raid and ram sticks to update OS first; then
had to update GPU driver;  Could not get it to boot other wise.

I don't think my setup is best.   Using linux software raid.  I would
like to have performance and back up on my HDD's.  I didn't go with
raid 5 cause I don't know how to restore in case failure occurs.  I
manually copy files onto the 500gb spare drive; I tried sbackup app
not working right as far as I can tell.  Does my set up need
improvement?  What do you guys recommend?  I would like performance.
I am willing to spend a few bucks to make improvements (add HDD's) if
necessary.

2 -750gb are partitioned --  500gb off of each for raid 0, 50mb off of
each for boot (wouldn't let me have it in raid 0), 250 gb off one for
Vista, and a 250gb blank ext3.
1 500GB is my manual backup.
