    There is no precompiled version for 5.3 but looking at the openbuild version
    its the same driver as the built in.
    80MB/s is still terrible should be looking closer to 200MB/s.

    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)
