1) The best option is SCSI on a trapdoor Blizzard (030,040,060,PPC)
card.
These cards use 32 bit DMA and are fassst with low CPU overhead.
2) PCMCIA SCSI is 16 bit and really slow with high CPU useage, avoid!
3) If you want a lot of devices SCSI is the way to go. IDE can have 4
devices with a Powerflyer adaptor. (See Eyetech and Powercomputing in
the UK or Softwarehut in USA for IDE options). For home use I do not
really think it matters IDE or SCSI, SCSI will be faster, lower CPU
useage, IDE will be alot cheaper.
4) Don't know :-)
