I've been trying both hw and sw raid. Now, I've got a new controller
giving me 60MB/sec from a software RAID-0. I haven't tried hw RAID on the
new controller yet, but I will.
The system is a Compaq ProLiant DL380: 3-peer PCI system with 1GBps memory
bus, 1,2GB RAM, 2xPIII1266 and a nice steel-gray 2U-case.
