Up to a point, but I find it irritating that I cannot turn off the floppy click
sounds on my Amiga emulator. If I record the Line Out from a real Amiga, it
doesn't have them, so why are they present in an emulated one?
Are working SCSI drives really that hard to find where
people would rather
spend $75 on an adapter that can't do 1MB/sec that even the old antique
drives can beat? I think using a USB thumb drive is more about convenience
being able to connect them to a modern PC to load up on programs then about
finding a working SCSI drive.
One word: IOPS.
That emulator will still be pushing 1MB/s while your tired old SCSI drive's
head staggers over to another track and twiddles its thumbs waiting for a
sector to come past.
In the case of the Amiga's "Fast" File System that doesn't have a
meaningful
disk cache and has each directory entry in a separate sector which can be
scattered all over the disk, seeks account for the vast majority of the time
spent waiting for I/O to complete.
