SAIT Tape Libraries

Qualstar Libraries

Over 343 Terabytes of Storage!
Qualstar SAIT Tape LibrariesQualstar was the first to integrate SAIT tape drives into automated tape libraries. The result was the renowned TLS-5000 series.

With over 343 terabytes of storage capacity (compressed), these units offer fast, reliable, enterprise class backup and near online data storage. In addition to sheer capacity, the SAIT tape format offers numerous other advantages, such as a blazing transfer rate of up to 2.2 terabytes per hour.

The SAIT series of tape libraries includes all the features and benefits of Qualstar’s other library models, such as Q-Link, VIOP, a barcode reader, and much more!
