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 th 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
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
