>=20

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=3D/dev/zero of=3Ddd.tst bs=3D1024 count=3D1048576
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?
