The Buffalo TS5420DN4804 is a 4-bay desktop NAS that provides 48 TB of ready-to-use storage through four pre-installed 12 TB NAS-grade drives. The system gives small and medium sized businesses an easy way to keep projects, backups, and shared files in one secure location on the local network.
A 2.04 GHz Annapurna Labs AL524 quad-core processor works with 8 GB of DDR4 memory, so large folders open quickly and multiple users can connect at the same time without slowdown. Dual 1 GbE ports handle everyday traffic, and a 10 GbE port steps in when graphic designers, video editors, or engineering teams need higher throughput.
The drives sit in hot-swappable bays, which means you can replace a failed unit while the TeraStation stays online. Flexible RAID options, including 0, 1, 5, 6, and 10 as well as JBOD, let you balance speed, capacity, and redundancy to match each workload.
Built-in 256-bit AES encryption and optional two-factor authentication help protect sensitive material, from client proposals to financial records. You can also schedule encrypted snapshots or replicate data to another TeraStation for an extra layer of insurance.
For teams that prefer a hybrid approach, the unit integrates with Dropbox, Amazon S3, and Microsoft Azure. This allows automatic off-site backups, easy sharing with remote colleagues, or quick recovery if the office ever experiences a hardware issue.
Whether you are an IT manager consolidating user folders, a marketing firm editing large media files, or a growing company that just needs a reliable place for daily backups, the Buffalo TS5420DN4804 delivers the capacity, speed, and security that keep work moving.
