Quantum DAT72 Autoloader

Quantum DAT72 Autoloader

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

• Network servers

• Loader products

• Online data collection

• Near-line secondary storage for text, graphics or multimedia information of all types

• Archival storage

The DAT 72 drives represent Seagate’s commitment to reliable engineering and durable tape drive products that implement leading-edge technology.

Key features of the drives include:

• A platform based on state-of-the-art sealed drive mechanism and tape-handling components for improved immunity to airborne contaminants and extended media life
