I have had one of these for several years (DDS2), with a BusLogic (now Mylex
I think) SCSI card. Works well. Just insmod BusLogic.o and away you go.

The only thing to beware is that you need to set a decent blocksize to write/read.
If you leave the standard CPIO one (1/2 K I think), it takes forever.
10K works well.
