Learn about Tape Storage Technology

The combination of tape systems and backup software enables organizations of any size to choose data protection that is right for them. Dell offers a wide range of common tape storage technology formats.

DDS/DAT
Abbreviation for Digital Data Storage, the industry standard for digital audio tape (DAT) formats. DAT is a type of magnetic tape that uses a scheme called helical scan to record data. A DAT cartridge is slightly larger than a credit card in width and height and contains a magnetic tape that can hold up to 36 gigabytes (native capacity) of data. Like other types of tapes, DATs are sequential-access media.

DLT/SDLT
Abbreviation for Digital Linear Tape, DLT is a type of magnetic tape storage device now developed mainly by Quantum Corporation. DLT tapes are ½-inch wide and the cartridges come in several sizes ranging up to 80 gigabytes (native capacity). SDLT (Super Digital Linear Tape) drives available from Dell can hold up to 160 gigabytes (native capacity) of data.

LTO
Abbreviation for Linear Tape-Open, LTO is the name applied to the Ultrium tape format optimised for high capacity and performance with outstanding reliability. Available in either single or multiple drive configurations, the LTO Ultrium tape format is ideally suited for enterprise-level backup, restore and archive applications. LTO is the open standard alternative to proprietary tape technologies (like DDS/DAT and DLT/SDLT described above) which results in interoperability across vendors and more economical product line for the user. Today, Dell offer LTO drives with capacities ranging up to 800 gigabytes (native capacity) of data (4^th generation LTO).
