• 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
• Support for various native data-storage capacities (see table 1
)
• High-speed transfer rates for fast backups (see table 1
)
• Advanced onboard DDS-DC hardware using Lempel-Ziv (DCLZ)

• 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
