Have you tried the driver supplied by Highpoint as a pre-compiled kernel module? I have a 1820A with 4x400GB Hitachi SATA disks (RAID5 + 1 Hot Spare) in a system running 5.3-RC3/amd64, where I have to use the kernel module, and I get almost double the speed that you have: -=- % dd if=/dev/da0 of=/dev/null bs=64k count=10000 10000+0 records in 10000+0 records out 655360000 bytes transferred in 7.775190 secs (84288614 bytes/sec) -=- Best Wishes - Peter -- [EMAIL PROTECTED] | ISC | OpenPGP 0xE8048D08 | "The bits must flow"
