Powerful performance

Equipped with an Intel Pentium N3710 quad-core 1.6GHz processor, My Cloud Pro Series NAS provides you with the power you need to transcode your media on-the-fly. Along with 4GB of DDR3L RAM mounted to dual slots (expandable to 16GB of DDR3L RAM), you get the power and efficiency to stream in high definition, access photos quickly and share content seamlessly.

Smooth video streaming

My Cloud PR4100 comes with built-in hardware transcoding, so your video is prepared for streaming through the Plex media server whenever you need it. With Plex, your media is enhanced with the appropriate descriptions, artwork, and metadata through an easy interface, so you can find and stream your favorite content to your PC, Mac, smart TV, or a supported mobile device.

Quick and easy setup

Featuring My Cloud OS 3, My Cloud PR4100 makes device setup simple and intuitive. Using a web-based installation process, My Cloud PR4100 is automatically found and installed through a robust device manager, so you're able to control and monitor your storage at home or from the road.

Comprehensive data protection
