There is also https://www.hyperossystems.co.uk/07042003/hardware.htm which I believe is a rebadged ACard drive. They should be SATA-300, but the test results I saw were not that impressive to be honest. I think whatever FPGA they use for the SATA interface and DRAM controller is either underpowered or the gate layout needs work.
