SimpleTech™ Zeus series solid state drives comprise the following primary functional
component blocks:
• ATA (IDE) Bus Interface
• SSD Control
• Flash Memory
2.1.1 ATA (IDE) Bus Interface Block
This section provides information on the ATA (IDE) Bus interface connectors used with
2.5-inch and 3.5-inch Zeus SSD.
2.1.1.1 44-pin ATA Bus Connector
The 2.5-inch Zeus-series SSDs are equipped with a 44-pin ATA bus connector
(Figure 3), located on the rear of the drive. DC power and IDE bus traffic is supplied
through a non-shielded 44-conductor I/O cable.
Figure 3. 44-pin ATA (IDE) Bus Connector
SimpleTech Zeus SSDs have a plastic key to block pin 20 on the ATA bus
(IDE) interface connector. Blocking pin 20 prevents possible damage to
the SSD by making it impossible to connect to the drive improperly.
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.
