Software raid actually - the box has Nvidia RAID in the bios but didnt work (at
all?) so ended up using gmirror in different layouts. A low end box :(
The controllers are 2 x nVidia nForce CK804 SATA300.
atapci1: <nVidia nForce CK804 SATA300 controller> port
0xdd002000-0xdd002fff irq 22 at device 7.0 on pci0
atapci2: <nVidia nForce CK804 SATA300 controller> port
0xdd003000-0xdd003fff irq 23 at device 8.0 on pci0
Drives are 4 x WDC WD2500JS-00MHB0 02.01C03

$ cstream -o tmpfile -v 1 -n 384m -i -
402653184 B 384.0 MB 6.91 s 58254333 B/s 55.56 MB/s
definitely not great throughput, but it'll have to do for now :-(
thanks a lot for the time to share your knowledge :)
