Centralized storage with anytime, anywhere access
Store and organize your photos, videos, music and files in one safe place. Access and share them anytime, from anywhere.

Powerful Marvell® ARMADA™ 388 1.6 GHz dual-core processor and 2 GB DDR3 memory gives you ultra-fast transfer speeds of 115 MB/s upload and 107 MB/s download for high-performance media streaming and file transfers.

Media streaming
With the built-in Twonky DLNA-certified media server, you can seamlessly stream all your HD content to media players, Smart TVs, gaming consoles and other DLNA-certified devices.

Comprehensive data protection

Backup that's right for you
Keep your irreplaceable photos, videos and files safe with multiple, automatic backup options for all the computers on your network. For PC users, WD SmartWare™ Pro offers options for how, when and where your content gets backed up. For Mac users, utilize all the features of Apple Time Machine to protect your content. You can also automatically "back up your backup" to another offsite My Cloud Expert Series device or to a supported cloud service, including Dropbox, ElephantDrive and Amazon S3.

Multiple RAID options
Armed with multiple RAID options, you have the power to customize the system with the configuration that works best for you. Choose RAID 0 for enhanced system performance; RAID 1 for mirrored data protection; RAID 5 for data protection and best capacity; or RAID 10 for fast performance and ultimate data reliability. Other options include JBOD and spanning.

RAID Roaming allows you to keep your RAID array intact when you move drives from one My Cloud EX4100 device to another. RAID Migration lets you change your RAID configuration and expand storage without losing content.

Advanced data security
256 AES volume encryption provides additional protection for your valuable photos, videos, music and files.

Recycle bin
With this optional feature, deleted files are not erased completely from the NAS, but moved to a special folder and can be retrieved, adding a second level of defense against accidental data deletion.

Easy to set up and manage
My Cloud EX4100 comes preconfigured for easy setup and system management. The intuitive dashboard guides you through the process of setting up users and shares, customizing system features and monitoring your storage. And with a toolless and trayless drive bay design, drive installation and hot swap is effortless.
