Tape Storage’s Economics are Still Compelling

Tape may seem archaic in the age of cloud-based and solid-state disk storage, but it still has a valuable role to play.

IBM says its scientists have set a new world record in tape storage, proving that the format is the ideal technology for migrating back-up and archival data on premise and in the cloud. Working with FUJIFILM of Japan, IBM scientists demonstrated a record areal recording density of 123 billion bits per square inch on tape, the equivalent of a palm-sized 220 TB tape cartridge. This also means a very low cost for tape-based storage – just a few pennies per gigabyte.
