Apparantly both Apple and Alliance Peripheral Systems manufacture just such
a device so they can still offer Powerbook SCSI upgrades even though there
are *no* 2.5" scsi drives in production anymore. Reportedly they are able
to get hundreds of KBytes/sec. throughput using the adapters! Whee!

That depends on how patient you are, I guess. ;-)
(It surprises me that the adapters are that slow, since I'm sure I saw equal
or better throughput with the old S[AC]SI-to-ST506 adapters, but the new
adapters are probably as cheap as absolutely possible, which certainly didn't
describe the old OMTI-20...)
