DK211C-51 Hard Disk Drive

The DK211A-51 and DK211C-51 offered 510 MB of storage, about the same as Hitachi’s 3.5-inch drives announced the previous year. The new drives were unique in that they operated on a single five-volt power supply and had an impact resistance while in operation of 100 G. The models differed only by their interface — an SCSI interface or an ATA interface — to match specific applications.
