WD MY CLOUD EX2 Ultra 8TB Network Attached Storage

The WD My Cloud EX2 Ultra 8TB is a powerful, easy-to-use 2-bay NAS designed to replace expensive cloud subscriptions with your own private, always-on personal cloud. Pre-loaded with two WD Red 4TB NAS drives and powered by a Marvell ARMADA 385 1.3 GHz dual-core processor, it delivers fast transfers, smooth media streaming, centralised backup, and remote access — all from a compact desktop device.

Performance-Ready Hardware

The Marvell ARMADA 385 dual-core processor, built on ARM’s Cortex-A9 architecture and 28nm process, combined with 1 GB DDR3 RAM provides the horsepower needed for simultaneous tasks — streaming 4K video, transferring files, running Plex Media Server, and serving multiple users concurrently — without lag or bottlenecks.

Pre-Loaded with WD Red NAS Drives

Both drive bays come populated with WD Red drives — specifically engineered for 24/7 NAS operation with NASware firmware for improved reliability, vibration tolerance, and compatibility. Tool-less, tray-less drive bays make upgrading or adding drives effortless when more capacity is needed.

Flexible RAID and Data Protection

Choose from RAID 0 for maximum 8TB combined performance storage, RAID 1 for mirrored 4TB redundant protection against drive failure, or JBOD/Spanning for flexible non-RAID configurations. Combined with 256-bit AES volume encryption, your data stays protected whether at rest or accessible over the network.

Private Cloud — Access from Anywhere

Through the My Cloud OS 5 dashboard, My Cloud mobile app, and MyCloud.com portal, access, upload, and share files from any device — smartphone, tablet, or computer — without relying on third-party cloud services or paying ongoing subscriptions. Share files via public or private links with customisable access permissions.

Media Streaming & App Ecosystem

Built-in Plex Media Server organises your photo, video, and music library for beautiful, lag-free streaming to PCs, smart TVs, mobile devices, and gaming consoles. A rich third-party app ecosystem extends functionality further with Dropbox sync, WordPress hosting, Milestone ARCUS Surveillance (2 camera licences included), and cloud backup via Amazon S3, ElephantDrive, and Acronis Cloud.

Centralised Backup for the Whole Household

Back up multiple PCs and Macs automatically — Windows users via WD SmartWare or Acronis True Image, Mac users via native Apple Time Machine support. WD Sync keeps selected folders automatically synchronised across all devices. Remote NAS-to-NAS backup and cloud backup add additional layers of data protection.

Backed by a 2-year limited hardware warranty and WD’s global support network, the My Cloud EX2 Ultra 8TB is the smart, cost-effective alternative to subscription cloud storage.
