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.
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
so presumably there is no attempt to emulate real hardware speeds in this area?
Of the storage mediums, only for floppies there's SW (e.g. copy
protections) that requires things to be as slow as with original
No, you're right - Hatari does not emulate the speed of a real ACSI
device / the DMA controller. It's rather working as fast as possible.
