            4MB is suggested for RAID-3 and RAID-5 operation.

                       MISCELLANEOUS TECHNICAL NOTES

  The IFT-3102 is a Wide-SCSI to Wide-SCSI RAID controller which provides
  RAID 0, 1, 3 or 5 independently of the host system’s operating system.

  The controller also comes with Ultra Wide single-ended upgrade board
  (IFT-9073UWS - diagram not available) and Ultra Wide differential
  upgrade board (IFT-9072UWD) - diagram not available.
