According to the Handbook:

   Slice numbers follow the device name, prefixed with an s, starting at 1.
   So ``da0s1'' is the first slice on the first SCSI drive. There can only be
   four physical slices on a disk, but you can have logical slices inside
   physical slices of the appropriate type. These extended slices are
   numbered starting at 5, so ``ad0s5'' is the first extended slice on the
   first IDE disk. These devices are used by file systems that expect to
   occupy a slice.
