Well... if we are using an IDE harddisk and the disk is less than about

If a long transfer is done with DMA, bus speed is an issue--otherwise
there are lots of software and protocol variations that can swamp
bus speed.

Put another way, if your system can come close to sustaining disk
data transfers at bus speed, then you have a _very_ fast storage
system!
