The My Cloud product line comprises personal network-attached storage (NAS) devices and multi-purpose servers, designed and marketed by Western Digital Corporation (WD).

My Cloud employs a Mindspeed Comcerto 2000 dual-core ARM Cortex-A9 Communication processor running at 650 MHz.

[2][3][4] On March 26, 2023 Western Digital encountered a cyberattack that led to unauthorized access to company systems and data theft.

As a precautionary measure, the company temporarily suspended some services, including My Cloud on April 2.

The suspension lasted for ten days, during which users were unable to remotely access files stored on their WD NAS devices.
