  • Product DetailsBack to top
  • The four bay Western Digital My Cloud EX4100 External NAS Drive gives you reliable backup and multi-volume storage space for high data volumes.

    Create a reliable storage space

    Equip your home or small office with a flexible and powerful NAS storage facility. Installation is simple and you'll be able to add up to four drives, expanding along with your requirements. This means you'll be able to install up to 32 TB of space to store your files, multimedia and much more.

    It's physically sturdy with an all-metal enclosure, and offers a complete set of apps to help you make the most of the drive's features.

    Superior drive management and safer data

    You'll have multiple options to save your data with the WD My Cloud EX4100, which lets you select RAID 0, 1, 5 or 10. Choose between spanning and JBOD modes for further data management options.

    The enclosure includes an intuitive dashboard and LCD display to make system control simple. Monitor your drives, manage users and activate energy-saving functions, with email and text alerts to keep you informed.

    Apps and software make things convenient

    The WD EX4100 Drive includes dynamic WD My Cloud mobile and desktop apps that let you upload, access and share documents from anywhere.

    Files can be conveniently transferred from public cloud accounts to the EX4100 without requiring a mobile app. Use leading apps such as aMule, Icecast, Joomla!, WordPress, Transmission, phpBB, phpMyAdmin and SqueezeCenter to customise the drive. The device also offers advanced serving options like an integrated file server, FTP server, backup server and P2P download server.

    Streaming to multiple devices

    Use your WD My Cloud EX4100 External NAS Drive to stream photos and videos to connected TVs, media players, gaming consoles and other DLNA/UPnP devices. The drive comes with a Twonky 7.2 and a DLNA-certified 1.5 media server plus a My Cloud EX4100 iTunes server for easy streaming from your music library.

    Personalised backup

    You'll be able to safeguard your data by remotely backing up to another My Cloud EX4100 – or using integrated cloud backup or local LAN/WAN backup.

    For PC users, WD SmartWare Pro gives you choices for how, when and where files are backed up for up to ten computers. Mac users can use all the features of Apple Time Machine to protect their data.

    Private cloud

    The WD EX4100 NAS Drive lets you store all your content in one safe place on your home or office network, rather than a remote server. You won't be limited by obscure data locations, monthly fees or other limits.

    Enjoy high-speed interaction with your saved files, and attach a compatible USB drive to one of the three USB 3.0 ports to increase your private cloud storage space.

    Find a better way to store your data with the Western Digital My Cloud EX4100 External NAS Drive.
