Buffalo 4TB LinkStation 220 Personal Cloud Storage NAS Drive (2 x 2TB)

The Buffalo LS220D0402 is a two-bay network attached storage system that gives you 4TB of personal cloud space that you control. It slips onto a shelf next to your router and connects through Gigabit Ethernet, turning every computer and mobile device on the network into a secure file hub.

The unit arrives with two 2TB SATA drives already installed. You can keep the full 4TB available by selecting RAID 0, or choose RAID 1 to mirror the drives for an added layer of protection. A JBOD option is also available when you want each drive to appear as a separate volume. Switching modes is handled through a clear, browser-based interface that guides you step by step.

Backup tasks that once took multiple programs can now run from a single place. Windows users can take advantage of the included NovaBACKUP software, while Mac owners can point Time Machine at the LinkStation for automatic, versioned backups. The NAS works quietly in the background, so laptops can stay light and desktops can stay uncluttered.

When it is time to enjoy your media, the built-in DLNA server streams music, photos, and movies to smart TVs, game consoles, and media players without extra configuration. An iTunes server is also on board for households that organize libraries through Apple devices. If you download large files, the integrated BitTorrent client lets the LinkStation handle the task even when your main computer is off.

Remote access turns the LinkStation into a private cloud. Whether you are at a client site, on campus, or traveling, secure web and mobile apps let you grab documents, share photos, or upload new work as if you were still at home. A rear USB 2.0 port can add extra storage or place a USB printer on the network.

This blend of capacity, flexibility, and simplicity suits families who want to protect growing photo libraries, creative professionals who move large project files between devices, and small-office teams that need a shared repository without monthly subscription fees.
