For EmuTOS-related reasons, I just measured the data transfer rate of an

If Hatari should emulate something in this regards, I think it
should be interface speed, not some ancient storage medium.
This IS interface speed I'm talking about. Real disks may be slower.
According to Wikipedia, first SCSI standard (on which ACSI is based?),
has max speed of 5MB/s, and the SCSI chip in TT has max speed of
4MB/s:

ACSI is only implemented on Atari systems, so the only relevant interface is on
real Atari hardware. If you can get I/O at over 1500KB/sec, you should tell
everyone how.
And the SCSI chip on the TT will not transfer at an effective rate above
2MB/sec.
