The Tandberg 8731-01-RDX 2TB Removable Disk Cartridge is a reliable backup storage solution in a cassette style. With a capacity of 2TB, this unit is perfect for storing large amounts of data securely. The Tandberg brand is known for its quality and durability, making this disk cartridge a trusted choice for businesses and individuals needing a reliable storage solution. I have had this in storage since 2019 when the business shut down.
