This is the same cost as a SCSI2SDv6.
Which will be a better solution depends heavily on what you're doing.
The three people actually capturing video or doing continuous software compiling on an x100 Power Mac might benefit from this kind of adapter, just because SD cards have longevity and performance issues in some write-heavy scenarios. It would, of course, need to be paired with an appropriate SCSI adapter or a card for this kind of adapter.
