The Free On-line Dictionary of Computing (19 January 2023):

winchester

    An informal generic term for floating head
   magnetic disk drives in which the read-write head planes
   over the disk surface on an air cushion.

   The name arose because the original 1973 engineering prototype
   for what later became the IBM 3340 featured two 30-megabyte
   volumes; 30--30 became "Winchester" when somebody noticed the
   similarity to the common term for a famous Winchester rifle
   (in the latter, the first 30 referred to caliber and the
   second to the grain weight of the charge).

Winchester
 n.

    Informal generic term for sealed-enclosure magnetic-disk drives in which
    the read-write head planes over the disk surface on an air cushion. There
    is a legend that the name arose because the original 1973 engineering
    prototype for what later became the IBM 3340 featured two 30-megabyte
    volumes; 30--30 became ‘Winchester’ when somebody noticed the similarity to
    the common term for a famous Winchester rifle (in the latter, the first 30
    referred to caliber and the second to the grain weight of the charge). (It
    is sometimes incorrectly claimed that Winchester was the laboratory in
    which the technology was developed.)
