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:
