The My Cloud is a line of personal Network-Attached Storage devices and multi-purpose servers designed and marketed by Western Digital Corporation. My Cloud devices come in sizes of 2 TB, 3 TB, 4 TB, and 8 TB. A newer, second model of My Cloud can have up to 16 TB.[1]


My Cloud uses a Mindspeed Comcerto 2000 (M86261G-12) 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 MB of Samsung K4B2G1646E DDR3 RAM and 512 KB of Winbound 25X40CL flash. The drive is a WD Red 2 TB (WD20EFRX).

My Cloud relies on air convection for cooling, without a fan.


My Cloud devices come pre-installed with My Cloud OS,[2] but it's possible to overwrite it with a custom, third-party OS.

My Cloud OS[edit]

The My Cloud OS is a proprietary operating system, with a user-friendly GUI,[3] which comes pre-installed on all My Cloud devices.[4]


My Cloud apps[edit]

The My Cloud OS is accessible from personal computers, Apple Macs, Android devices, and iOSs, via an application provided by Western Digital.[2][3][4]
