Gigabit Ethernet Port The 10/100/1000 Mbps auto-negotiating Ethernet port
allows the NSA to detect the speed of incoming
transmissions and adjust appropriately without manual
intervention. It allows data transfer of either 100 Mbps or
1000 Mbps in either half-duplex or full-duplex mode
depending on your Ethernet network. Use an 8-wire
Ethernet cable for Gigabit connections. The port is also auto-
crossover (MDI/MDI-X) meaning it automatically adjusts to
either a crossover or straight-through Ethernet cable.
Actual data throughput varies depending on the network
conditions and environmental factors, including volume of
network traffic, network overhead and building materials.
SATA Interface Serial ATA is a low cost interface technology that allows high
speed data transfer. Serial ATA also allows more efficient
internal airflow and smaller chassis design.
