The DAT 72 drives combine established DAT technology, high-density recording and hardware data-compression capability along with Seagate’s proven computer-grade design to provide unmatched reliability and performance characteristics among DDS products.
Features
The following list summarizes the key features of the DAT 72 autoloader drives.
Compatibility
• DDS-4: Supports DDS-2, DDS-3, and DDS-4 recording formats.
• DAT 72: Supports DDS-3, DDS-4, and DAT 72 recording formats.
• Support for various native data-storage capacities
• High-speed transfer rates for fast backups
• Advanced onboard DDS-DC hardware using Lempel-Ziv (DCLZ) data-compression, doubling the drive’s uncompressed capacity (e.g., a 20 GB uncompressed drive can be 40 GB with compression)
• High-performance SCSI burst transfer rates
• Three levels of error-correction code (ECC) and four-head design for read-after-write (RAW) error detection and correction (uncorrectable error rate of less than 1 in 10 15 bits)
• “Flying” preamplifier for greater signal-to-noise ratio
• Flash memory to store setup parameters and enable field firmware upgrades
• Automatic Power On Self Test
• State-of-the-art sealed drive mechanism and tape handling components for improved immunity to airborne contaminants and extended media life.
Data Storage Capacity: 36 Gbytes (72 Gbytes compressed)
Native Transfer Rate:3.5 Mbytes per second (7.0 Mbytes per second compressed)
The DAT 72 drives combine established DAT technology, high-density recording and hardware data-compression capability along with Seagate’s proven computer-grade design to provide unmatched reliability and performance characteristics among DDS products.
The DAT 72 drives are ideal for workstation, server, and network/enterprise applications such as:
• Backup of high-capacity fixed discs
• Data interchange between systems
