Buffalo TeraStation 5420RN 80TB 4-Bay Rackmount NAS Server

The Buffalo TS5420RN8004 is a rackmount network attached storage server that delivers 80 TB of space for teams that need dependable, on-premises data management. It arrives with four 20 TB drives that can be swapped while the system stays online, so growing companies can expand or replace storage without interrupting work.

Inside, a 2.04 GHz Annapurna Labs AL524 processor works with 8 GB of DDR4 memory to keep file transfers and backups moving quickly. Dual 1 GbE ports handle everyday traffic, while an additional 10 GbE port is ready for bandwidth-heavy tasks such as large media projects, virtualization, or rapid disaster recovery.

Data protection is built in. Choose from RAID 0, 1, 5, 6, 10, or JBOD to match your balance of speed and redundancy, then add 256-bit AES encryption and two-factor authentication to keep sensitive information secure. The system also connects to popular cloud services including Dropbox, Amazon S3, Microsoft Azure, and OneDrive, giving you flexible off-site sync and backup options without extra gateway hardware.

The 1U rackmount chassis slides into standard server racks and integrates easily with existing networks, making it a practical upgrade for branch offices, creative studios, and small to medium businesses that want enterprise-grade storage without complicated setup.
