2.1.1.23.5-inch SSD ATA Interface and Power Connectors

The 3.5-inch Zeus-series SSDs are equipped with a 40-pin, DC power/ATA bus combination connector (Figure 4), located at the rear of the drive. IDE bus traffic is supplied through a non-shielded 40-conductor I/O cable. DC power is supplied through a separate 4-conductor power cable.

ATA standards require 80-conductor cables to be used for Ultra DMA modes 3 through 5. The length of the cable shall not exceed 18 inches.

Except as noted, the table applies to both the 44- pin ATA bus connectors (Figure 3 on page 13) on used 2.5-inch drives, and the 40-pin ATA bus/DC power combination connectors (Figure 4 above) used on 3.5-inch drives.
