I guess you mean 53c810 for 52c810. It is the most less expensive SCSI-2
controller and has the performance reach the SCSI-2 spec.
I got 6.6 MBps reading rate on a sigle Seagate Baracuda disk and
8.5 MBps reading rate on double Seagate Baracuda disks on the same controller.
It costs $55 now from ACME MICRO-SYSTEM Inc., and about $69 - $79 other places.
