There's a huge divide between people who might play with this at home as a toy and those who would be able to work with professional musicians with it.
The latter group will have some very strict requirements around performance, latency and workflow.
Edit: and reliability
DSP based systems struggled a lot with IO in the late 90s until faster SATA drives became ubiquitous. Lots of them used SCSI or exotic hardware cards to deal with large track counts.
It did have a SCSI drive, but in 1999 I did not consider that "exotic", having been using them on various Unix workstations for more than a decade before that.
