Hardware
My Cloud uses a Mindspeed Comcerto 2000 dual-core ARM Cortex-A9 Communication processor running at 650 MHz. The gigabit Ethernet port is a Broadcom BCM54612E Gigabit Ethernet transceiver. Other components include 256 megabytes of Samsung K4B2G1646E DDR3 random access memory and 512 kilobytes of Winbound 25X40CL flash memory. The drive used is a WD Red 2 terabyte hard drive.
My Cloud relies on fanless air convection for cooling.

My Cloud OS
My Cloud comes pre-installed with the My Cloud OS (operating system).[2] However, it is possible to overwrite it with a custom, third-party operating system.
This operating system is proprietary, with a user-friendly graphical user interface. However, others have found the operating system to be Linux, with a graphical user interface, but also SSH accessible.[3] which comes pre-installed on all My Cloud devices.[4]
Compatibility
My Cloud apps
My Cloud is compatible with personal computers, Apple Macs, Android devices, and iOS devices, via an application provided by Western Digital.[2][3][4]
Incidents
On March 26, 2023, Western Digital experienced a cyberattack breaching the company's systems and stealing some data. On April 2, the company proactively took some services offline, including My Cloud, to examine the extent of the intrusion. My Cloud was restored after ten days preventing its users from accessing files stored on their WD NAS devices during the downtime.[5][6]
