z
3.5-inch internal form-factor for installation in a 3.5-inch half-height space
(model STD124000N)
z
3.5-inch drive with factory-installed 5.25-inch mounting rails and bezel for
installation in a 5.25-inch half-height space (model STD224000N)
z
External subsystem with built-in, auto-sensing, worldwide power supply (model
STD624000N)
z
Capability to write and read DDS-3, DDS-2, DDS-DC and DDS cartridges
z
Advanced onboard DDS-DC hardware using Data Compression Lempel-Ziv
(DCLZ) data-compression algorithm
z
ANSI/ECMA DDS-3, DDS-2, DDS-DC and DDS tape format compliance for
compatibility and interchange
z
High-speed random access of 20 seconds (average) to any file on a 60 m tape;
30 seconds for a 90 m tape; 40 seconds on a 120 m tape; and 40 seconds on a
125 m tape
