Buffalo TeraStation 5420DN 64TB 4-Bay Desktop NAS Server

The Buffalo TS5420DN6404 is a four-bay desktop NAS server that delivers 64TB of storage right out of the box, thanks to its four pre-installed 16TB drives. It gives small and mid-size businesses a dependable way to centralize files, run scheduled backups, and share large media projects without leaning on public cloud space.

Inside, a 2.04 GHz Annapurna Labs AL524 processor works with 8 GB of DDR4 memory to keep file transfers smooth even when several users connect at once. Creative teams can stream high-resolution video directly from the unit, while office staff can edit documents on the network without slowdown.

Two 10 GbE ports and two 1 GbE ports make it easy to slot the TeraStation into an existing network and let you choose the speed that matches your infrastructure. USB-A 2.0 and USB-A 3.2 Gen 1 ports add quick paths for importing data from external drives or backing up critical folders.

The system supports RAID 0, 1, 5, 6, and 10, plus JBOD, so you can balance performance, redundancy, and capacity to suit evolving needs. Hot-swappable drive bays let you replace a drive on the fly, keeping downtime to a minimum.

Data protection is built in. Hardware-based 256-bit encryption keeps stored information unreadable if drives are removed, and two-factor authentication adds another layer when users log in. For off-site copies, integrations with Dropbox, Amazon S3, and Microsoft Azure allow automated cloud replication without extra software.

Whether you manage a design studio that juggles large media files, an engineering firm that stores project data, or an IT department that oversees routine backups, the TS5420DN6404 offers the capacity, speed, and security you need in a compact desktop footprint.
