The Buffalo TS51220RH4804 is a rackmount network attached storage server that gives your organization 48 TB of enterprise-grade capacity and the flexibility to grow. Twelve drive bays provide headroom for expansion, yet four 12 TB drives arrive already installed, so you can start protecting data immediately without a long setup.

A 2.04 GHz quad core processor partners with 16 GB of DDR4 memory to keep file transfers responsive even when many users connect at once. Creative teams working with large video files, offices that rely on virtual machines, and branch locations that need a shared repository will all benefit from the consistent performance that the system delivers.

The TeraStation operating system lets you choose the balance of speed and redundancy that fits each workload. You can configure RAID 0, 1, 5, 6 or 10 for common scenarios, or fall back to JBOD when independent disks make more sense. When capacity or maintenance demands change, the hot-swap design lets you replace drives without shutting the array down.

Dual 10 GbE ports move large projects quickly and shorten backup windows, while two additional 1 GbE ports add compatibility and failover options. Security has been considered as well. Data at rest can be protected with 256-bit AES encryption, and two-factor authentication guards the management console against unauthorized access.

The system integrates smoothly with Microsoft Active Directory and VMware environments and can replicate or tier data to Dropbox, Amazon S3, or Microsoft Azure for disaster recovery. Whether you are a small and midsize company that needs centralized storage, an IT administrator looking to consolidate file servers, or a video production house that juggles multiple editing projects, the TeraStation 51220RH provides a solid, scalable foundation.

Highlights:
  • 48 TB raw capacity supplied by four pre-installed 12 TB enterprise drives
  • 12-bay rackmount chassis with hot-swap capability for painless maintenance and future expansion
  • Dual 10 GbE and 1 GbE ports deliver high transfer speeds and link redundancy
