Quantum Travan TR20 Tape Drive

The Seagate internal STT20000 SCSI minicartridge drive extends the Seagate family of one-inch high, DC2000 drives that feature high performance, high reliability, and quiet operation.


The STT20000 SCSI minicartridge drive transfers data at up to 60 megabytes per minute (Mbtyes/min) without data compression.

With optimal system resources available, and with compressible data structures, nominal transfer rates of up to 120 Mbytes/min can be observed using software data compression (assumes 2:1 compression ratio).

An additional feature of the STT20000 SCSI minicartridge drive is an option for Read While Write and Hardware data Compression. These features are available on the NS series (STT20000N-C). Highlights of these features are contained in various parts of this Product Description Manual.
