Buddha Flash Phoenix Edition faster?

[Zac67]

And don't forget about using Zorro II DMA controllers on a '030/040 machine: there's no way the SCSI controller can write to 32 bit memory (beyond 24 bit address range), so data has to be copied from slow Z2 RAM (that you hopefully have on the controller) to fast 32 bit RAM - might still be faster and more CPU efficient than IDE since the copy can take place in one piece and there's no constant polling on the interface.

The best solution is a Z3 SCSI controller (not many around) or an accelerator integrated one.

However, if you're not doing I/O intensive and CPU stressing tasks simultaneously, this discussion is more academic. The FastATA is probably the easiest way to improve speed.

Synchronous transfer is simply faster, and there's Ultra SCSI beyond that, too.  ;-) (plus U2W, then U160, U320 - sigh...)

My old A3000 can do ~8 MB/s with a 15 year old 1 GB Toshiba, that's pretty much all you get out of async SCSI. 10kRPM drives can easily do 40 MB/s.

It also speeds up 'simultaneous' I/O transfers on several disks because it reduces bus load.
