Machine now is a Athlon64 3400+ (Socket 754) equipped with 1GB of RAM. The four RAID disks are attached to the board's onbaord sATA controller (Sil3114 attached via PCI) Kernel is 2.6.21.1, custom on Slackware 11.0. RAID is on four Samsung SpinPoint disks, has LVM, 3 volumes atop of each XFS. The machine does some other work, too, but still I would have suspected to get into the 20-30MB/s area.
