Caleb UHD144

The Caleb Technology UHD144 (Ultra High Density) is a floptical-based 144 MB floppy disk system introduced in early 1998, marketed as the it drive. Like other floptical-like systems, the UHD144 can read and write standard 720 KB and 1.44 MB 3½-inch disks as well. Its main advantage was the low cost of the media, which averaged about $5 shortly after introduction — in wider production prices would have fallen.

The UHD144 had little chance in the marketplace, being squeezed out by the Iomega ZIP and Imation LS-120 for floppy large-storage needs, and the rapid introduction of the writable CD-ROM shortly after its introduction. The company went bankrupt in early 2002.
