From WordNet (r) 3.0 (2006) :

      n 1: interface consisting of a standard port between a computer
           and its peripherals that is used in some computers [syn:
           small computer system interface, SCSI]

From V.E.R.A. -- Virtual Entity of Relevant Acronyms (February 2016) :

         Small Computer Systems Interface (SCSI)

From The Jargon File (version 4.4.7, 29 Dec 2003) :

      [Small Computer System Interface] A bus-independent standard for
      system-level interfacing between a computer and intelligent devices.
      Typically annotated in literature with ?sexy? (/sek'see/), ?sissy? (/sis?ee
      /), and ?scuzzy? (/skuh'zee/) as pronunciation guides ? the last being the
      overwhelmingly predominant form, much to the dismay of the designers and
      their marketing people. One can usually assume that a person who pronounces
      it /S-C-S-I/ is clueless.

From The Free On-line Dictionary of Computing (30 December 2018) :

  Small Computer System Interface
      (SCSI) /skuh'zee/, /sek'si/ The most
     popular processor-independent standard, via a parallel bus,
     for system-level interfacing between a computer and
     intelligent devices including hard disks, floppy disks,
     CD-ROM, printers, scanners, and many more.
     SCSI can connect multiple devices to a single SCSI adaptor
     (or "host adaptor") on the computer's bus. SCSI transfers bits
     in parallel and can operate in either asynchronous or
     synchronous modes.  The synchronous transfer rate is up to
     5MB/s.  There must be at least one target and one
     initiator on the SCSI bus.
     SCSI connections normally use "{single ended" drivers as
     opposed to differential drivers.  Single ended SCSI can
     suport up to six metres of cable.  Differential ended SCSI can
     support up to 25 metres of cable.
     SCSI was developed by Shugart Associates, which later became
     Seagate.  SCSI was originally called SASI for "Shugart
     Associates System Interface" before it became a standard.
     Due to SCSI's inherent protocol flexibility, large support
     infrastructure, continued speed increases and the acceptance
     of SCSI Expanders in applications it is expected to hold its
     The original standard is now called "SCSI-1" to distinguish it
     from SCSI-2 and SCSI-3 which include specifications of
     Wide SCSI (a 16-bit bus) and Fast SCSI (10 MB/s transfer).
     SCSI-1 has been standardised as ANSI X3.131-1986 and
     ISO/{IEC">ISO/{IEC 9316.
     A problem with SCSI is the large number of different
     connectors allowed.  Nowadays the trend is toward a 68-pin
     miniature D-type or "high density" connector (HD68) for
     Wide SCSI and a 50-pin version of the same connector (HD50)
     for 8-bit SCSI (Type 1-4, pin pitch 1.27 mm x 2.45 mm).
     50-pin ribbon cable connectors are also popular for internal
     wiring (Type 5, pin pitch 2.54 mm x 2.54 mm).  Apple
     Computer used a 25-pin connector on the Macintosh computer
     but this connector causes problems with high-speed equipment.
     Original SCSI implementations were highly incompatible with
     each other.
