1 September 2022 - Due to ongoing global semiconductor component shortages, we're unable to produce more SCSI2SD V5 and V6 boards at this time. As a result of these shortages, Rabbit Hole Computing has developed an alternative SCSI emulation product, ZuluSCSI. Check out ZuluSCSI instead. It's SCSI command handling code is inherited from SCSI2SD V6, and it performs significantly better than SCSI2SD V5 in nearly all benchmarks. ZuluSCSI is a great alternative to SCSI2SD, and available for purchase today from Rabbit Hole Computing
