The FS-FD351 is a 3.5" double-sided, double-density 720kB (2DD) floppy disk drive, released by National, and meant to be used in combination with the FS-CF351 interface adapter. The drive was available in all black or black and silver.

The drive has a pass-through power connector for a second drive, but the data cable for the second drive connects directly to the interface adapter.

The interface supports up to two drives, which attach directly to the rear of the cartridge.

It includes a ROM with version 1 of the Disk BASIC instructions.
