Follow-up, did the same dd on a Dell 2850 with a LSI Logic (amr), 6 scsi-disks in a raid 5:
frodo~%>dd if=/dev/zero of=dd.tst bs=1024 count=1048576 1048576+0 records in 1048576+0 records out 1073741824 bytes transferred in 8.972321 secs (119672693 bytes/sec)
Must faster. FreeBSD 5.4 RC2.
Are there any benchmarks comparing the atabeast against other ide->fc-storage-systems in relation to disk-access?
That's about what I expected. RAID 5 depends on fast xor, so a slow processor in a hardware RAID5 box will slow you down a lot.
You should try taking the two RAID5's (6 disks each) created on your original controller and striping those together (RAID 50) - this should get you some better performance, probably not as close as the amr device, but I would guess somewhere in the 80-90mb/s range.
