We should have a speedup.
But an improvement can also be to interface a _real_ SCSI disk and send directly to it the SCSI commands generated by the _virtual_ SCSI interface (as it is done in BasiliskII emulator)

(I didn't notice any)? Can the PC boot from a SCSI-mounted device (I did
not succeede)?

To be able to boot from a SCSI disk we need a BIOS extension managing the SCSI card and allowing the BIOS to load the boot sector from the SCSI disk.
