Seagate / Conner CTD8000 DDS2 DAT

The Conner CTD8000R-S Digital Audio Tape (DAT) drives are fully integrated systems that support the Digital Data Storage Data Compression (DDS-DC) and Digital Data Storage-2 (DDS-2) tape formats.

The DDS-2 format provides for writing data in helical tracks that are narrower than standard DDS track width, allowing 50 percent more tracks on a tape. These drives also contain an embedded, single-ended SCSI controller. These drives provide a native transfer rate of 400 kilobytes/second (KB/sec) before the additional enhancement of data compression or high density recording (DDS-2 format).
