I have a GVP 2000 HC+8 controller, will that be faster than the internal IDE?


"Faster" is a relative term.  It's possible scsi.device and a relatively modern IDE Drive would give good results provided you had a decent cpu because Commodore's native controller does not use DMA nor FastATA modes.

The GVP board by contrast is a DMA controller (albeit a 24-bit one on the Zorro II bus).  A good SCSI drive will yield good transfer results (2+MB/s) but what is more important in the equation is the DMA ability of the card, which means the cpu will not be so bogged down doing PIO transfers as with the Amiga's native IDE scsi.device.  Of course, it's a different story if you are using scsi.device on an A3000 or A4000T, which have DMA scsi controllers built-in.

A couple of questions:

Can you switch on asynchronous mode on the CyberstormPPC/MarkIII without having to then reformat your existing scsi drives?

How do you swith on asynchronous mode on the A3000?
