Updated One Computer; some comparisions

3.04 74.2 Crosshair 7.02
3.21 71.8 M2n32 9.69
2.91 102.73 (Raid0) M2n32 8.14
3.19 75.0 Crosshair 7.44
3.00 70.7 M3n78 6.32

The Crosshair and M3n32 have the same 590 SLI chipset. The M3n78 has a worse one looks like. The 2nd computer has 4X1G the others 2X2G. All are AMD athlon X2.

The 3rd computer has a pair of raid0 raptors all the others are single raptors 16M cache 1.5G Sata. All have 15-5-5-5 PC 6400 memory.

Well stright up the m2n32 Premium is just a better motherboard. Raid0 is better but not double at all. Processor speed has little no effect on drive speed (duh). Raid0 gets you from 70 to 100 about or like 35percnet more speed. A single 300G raptor with sata 3.0 interface is aoubt 93.

So 70 for a single 1.5 sata raptor
93 for 3.0 sata raptor
103 for two 1.5 raptors in Raid0

Looks like 4 chips is better then 2 chips for memory bandwidth the cpu speed should only make for 8.1 to 8.9 from the 3rd to 2nd computers. The difference from 8.9 to 9.6 must be the fact of 4 way interleaving ...
