CMS SCSI - A piece of ****.  This thing can't support partitions larger than
           32MB, so watch out if you have a large drive cause you
           will be littered with paritions.  Slow card too, no DMA.

RamFAST - DMA plus caching.  Fast.  However, this card has some
          compatibility problems with software and hardware.
          For one thing, you can't use drives that require the
          controller to have an SCSI ID.  For another, it has
          DMA problems with  some revisions of both of the IIGS
          accelerator cards.  Partitions can be much larger than
          32MB, but only 12 can be online at once.

Apple High Speed SCSI - DMA controller.  A little slower than the
         RamFAST, but the most stable and compatible of the
         SCSI cards.  It will take drives that the RamFAST
         won't.  It also allows more than 12 partitions online.
         Partitions can be much larger than 32MB.  It also
         has NO DMA problems with drives that the
         RamFAST has problems with.
