The HP DAT 20/40 (part number: 157769-B21) is a reliable tape drive designed for efficient data storage and backup needs. This drive supports the Digital Audio Tape (DAT) format, specifically designed for the DDS-4 (Digital Data Storage) standard, offering a storage capacity of up to 20GB (native) and 40GB (compressed). The drive is equipped with a SCSI interface, ensuring compatibility with many legacy systems that rely on SCSI connections for communication between hardware devices.
One of the major benefits of the HP DAT 20/40 is its high transfer rate, capable of transferring data at speeds of up to 3 MB/s (native), or 6 MB/s (compressed). This allows users to perform necessary backups quickly in both small and medium business environments. The drive is also designed with read/write reliability in mind, supporting multiple read and write head passes to ensure data integrity during backup and restore operations.
The HP DAT 20/40 utilises Helical Scan technology, enabling extended data retention while maintaining compact tape media. It is capable of reading and writing to several different DDS formats, thus ensuring broad usability and compatibility with older media standards. For easy installation, the drive can fit into standard 5.25-inch drive bays, making it an ideal upgrade or replacement solution for SCSI-based systems requiring reliable tape backup capabilities.
