Adaptec USB2Xchange is one that kept popping up when I looked for
just such a thing years ago. Acquired one some time ago (from EBay,
because of course the product has been EoL for years).
Haven't used it yet, but it presumably works reasonably well.

There is a whole collection of SCSI device emulators out there and
they usually tend to use SD or CF cards for actual storage.

It helps that a lot of the pro DSLR cameras used CF as storage for quite
some time, so card readers for CF should be easy to find.
Kind regards,
