Introduction Features

Features

The following list summarizes the key features of the DDS-4 and DAT 72 drives.

• Compatibility

• DDS-4: Supports DDS-2, DDS-3, and DDS-4 recording formats.

• DAT 72: Supports DDS-3, DDS-4, and DDS 5

Generation recording formats.

• LVD / Ultra Wide SCSI connection

• Three convenient form-factors:

• 3.5-inch internal form-factor for installation in a 3.5-inch half-height space

• 3.5-inch half-height drive factory-installed with 5.25-inch mounting rails and bezel for

installation in a 5.25-inch half-height space

• External subsystem with built-in, auto-sensing, worldwide power supply

• Support for various native data-storage capacities (see Table 1 on page 13)

• High-speed transfer rates for fast backups (see Table 1 on page 13)

• 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). See Table 1 on page 13.

• 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

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
