Mmm… This is a bit of a puzzle! SCSI was a great system! But it’s performance peaked! I have never seen or heard of a SCSI to SATA solution, I wish there was! I have a collection of JAZZ 2TB drives which I would love to use for backups again.
I’m sure someone could create such a converter, I doubt it would fit or could be powered by the internal PS.
The trick is to get a SCSI PCI board to get the SCIS chip and support chips as well as a SATA to PCI then using a micro-controller to drive the PCI logic and move the signal across. This requires some serious micro code for the controller.
