| The Floppy Disk drive [FDD] is considered a legacy product at this point [functionally obsolete], still in
production but not recommended for new designs. The transfer speeds are
relatively slow, and the data storage capacity vary low. Data transfer
speeds for Floppy Disk Drives [FDD] normally are 250KBps for the 720KB
disk size and 500KBps for the 1.44MB disk size. However 1.25MBps may also
be found on some drives. FDD spin at a nominal rate of 300 RPM. Common power dissipation over the 5 volt line will be in the range of 1.25 watts. Bit Density for the two common size Floppy Disks are 8717 bpi [Bits per Inch] for the 720KB size and 17434 bpi for the 1.44MB size. Two common size devices are produced for the 3.5 inch floppy drive; the standard version 25.4 x 101.6 x 146mm [H x W x D], and a reduced size version 12.7 x 96 x 126mm [H x W x D]. There are still a number of companies that Manufacturer Floppy Disk Drives, a number of the companies are listed above.. The internal case drives use the FDD pinout described on the linked page, while external drives normally use a USB interface. |
