Orvar, around 50 to 60 MB/sec I've seen when zwo disks are writing and around 100MB/s when reading round-robin.
The limiting faktor has been the old PCI-Bus (*not* 32-Bit slot length) and in another test the 1-lane PCI-X bus. (Sil680/SIL3124-2 and SIL3132 Chip) So if you can see the difference being faktor 2 between reading and writing when using a 1:1 mirror setup, I would say, you hit the bottleneck of your PCI-Bus.
