SEAGATE STD64000N 2/4GB DAT DDS-1 SCSI EXTERNAL TAPE DRIVE

Seagate 2000, 4000, and 8000 Series Digital Audio Tape (DAT) drives are designed for computer environments requiring high performance, high capacity data storage. Based on a 3.5-inch mechanism, these internal and external drives provide a native transfer rate of 550 kilobytes/second (KB/sec). The primary differences between the series of DAT drives are the formats supported by the drives. The 2000 series drives support the DDS format; the 4000 series drives support the DDS and DDS-DC formats; and the 8000 series drives support the DDS, DDS-DC, and DDS-2 formats. All of the drives provide an embedded, single-ended Small Computer Systems Interface (SCSI) controller. The drives are equipped with a 1-megabyte (MB) on-drive buffer to facilitate efficient operation. In addition, the drives offer electronically erasable, programmable, flash memory, which enables qualified Seagate OEMs to download revised firmware to the drive via three methods: using the drive's serial port, the SCSI bus, or a specialized firmware cartridge. All of the drives comply with the American National Standards Institute (ANSI) and European Computer Manufacturers Association (ECMA) DDS format, which ensures interchange compatibility of digital data stored on a small removable DAT cartridge (approximately 2 inches x 3 inches x 0.4 inch) using 4 mm tape. The 4000 and 8000 series drives also comply with the ANSI/ECMA Digital Data Storage Data Compression (DDS-DC) format, which is the industry standard format for DAT data compression and is a superset of the DDS format. These drives use an advanced DCLZ (data compression LempelZiv) algorithm to compress data by up to two or more times. Importantly, DDS-DC data compression is transparent to the host software and SCSI driver.
