Buffalo TeraStation 5420DN 80TB 4-Bay Desktop NAS Server

The Buffalo TS5420DN8004 is a four bay desktop network-attached storage server that arrives with four pre-installed 20TB drives for a total of 80TB of raw capacity. It provides small and mid-sized offices with a dependable hub for organizing, sharing, and safeguarding large files, archives, and media projects.

An Annapurna Labs AL524 processor teams with 8GB of DDR4 memory to keep transfers smooth even when several users access the system at once. Two 10-Gigabit Ethernet ports handle high-bandwidth workloads such as 4K video editing or virtualization traffic, while two additional 1-Gigabit ports maintain compatibility with existing switches and routers.

Each drive bay is hot swappable, so a failed disk can be replaced without shutting the unit down or interrupting team members. The NAS supports RAID 0, 1, 5, 6, and 10 as well as JBOD, allowing you to choose the balance of speed, capacity, and redundancy that fits your workflow.

Security features include hardware-based 256-bit AES encryption and optional two-factor authentication, both designed to keep confidential data out of the wrong hands. Built-in connectors for Dropbox, Amazon S3, and Microsoft Azure make it easy to create off-site copies for disaster recovery.

Certification for VMware and Microsoft Hyper-V lets IT administrators present the device as shared storage or a reliable target for virtual machine backups. Whether you run a creative studio that needs fast access to massive media files or a branch office seeking an on-premises backup appliance, the TS5420DN8004 delivers capacity, speed, and peace of mind in one straightforward package.
