Your computer is an Amiga 4000 Tower.

I also have a Toccata sound card but it is not plugged in at the moment because it needs fixing (one channel is not working properly)

I have 1 sata hdd, one sata ssd, and two ide hdds connected to CybertormPPC scsi3 interface using acard 2x 7730a and 2x 7720UW

What should maxtransfer rate and mask should be set at? I'd rather the hdds use the fast 128mb memory of CyberstormPPC and not the slow 16mb onboard memory or the even slower 256MB ZorRAM memory.

Which RAM is used is determined by memory priority. With Mask and Maxtransfer you can only create more overhead, you cannot change which kind of memory is used. Memory priorities should already be so that the fastest memory is used first.

The CSPPC should not have any limits regarding Mask and MaxTransfer, so the defaults of Mask = 0x7FFFFFFE and MaxTransfer = 0xFFFFFF should be ok.
