I tested software RAID 0 via VINUM on FreeBSD 5.1 three hard drive IBM
Ultrastor IC35L073VCD210 connected to onboard Adaptec dual chanel AIC-7899W
based controller (64 bit 66MHz PCI), and compared them to Adaptec 2100 RAID
controller (32 bit 33MHz PCI). The performance hardware RAID is appeared
on 15 % less than VINUM. CPU usage is same.
Test utils are rawio and dd with many fork process (8).
The CPU are Xeon 2.4 GHz, SuperMicro MB P4DP6Q with Intel E7500 Chipset.
