THE MY CLOUD EX4 INTERIOR

Getting inside the My Cloud EX4 is not hard, just remove the 5 screws at the rear and pull the top cover backwards (as usual since we don't want to compromise the unit in any way we will not be taking it apart).

On the main PCB we see a 2GB SLC Flash module by Samsung and 512MB DDR3-1600 module by Nanya (10-10-10 timings).

We also see the Marvell 88SX7042 4 Port SATA II controller and the EtronTech EJ168A USB 3.0 Host Controller.
