5.3.1.2 Supporting 4 SATA Drives with 6 Pin Connector Details
If a system designer needs to support more than 2 SATA devices per connector on the
board a 6-pin storage drive power connector is defined. With a total of 6 pins the
number of SATA devices that can be supports is 4 devices. The Micro Fit connector will
only support 5 amps per pin, because of that the 12V wire can only support 2 drives in
Series. To support more than 2 drives the cable would have to be in a “Y” shape with
2 drives on each leg of the “Y”. The 5V current is more than half of the 12V current
therefore the one 5V pin can be used to support 4 SATA devices.
Using the 6-pin motherboard connection with the key solutions provided below allows
both the 6 pin (2x3 – supporting 4 drives) and 4 pin (2x2 – supporting 2 drive) cables
to be plugged into the 6 pin (2x3) motherboard connector. Notice the 6-pin
motherboard connector latch is wider to support the latch from both the 4 pin (2x2)
and 6 pin (2x3) cable connector.
