Product identity

The Buffalo Technology TS5420RN8004 is a 1U rackmount network-attached storage appliance pre-populated with four 20 TB NAS-grade hard drives for a total of 80 TB. It targets small and medium businesses that need a ready-to-deploy file server with integrated cloud backup and virtualization certification.

Deciding specification

A single native 10 GbE RJ-45 port sits alongside two 1 GbE ports, so the appliance fits straight into existing copper infrastructure without additional transceivers or cable upgrades. Buyers whose network core stops at 1 GbE will not benefit from the higher-speed uplink.

Bundled value

Drives arrive pre-tested and RAID-configured, eliminating the usual burn-in and array-build steps before production use. The package also includes a quick setup guide, AC power cable and warranty statement, while the management console enables centralised monitoring of multiple units from one interface.

Perguntas sobre este artigo

How does the 80 TB raw capacity translate into usable space once RAID is configured?

With four 20 TB drives installed, RAID 5 yields about 60 TB usable, RAID 6 about 40 TB, and RAID 10 about 40 TB before formatting overhead.

What network speeds do the IEEE 802.3, 802.3u and 802.3ab ports actually deliver?

The standards cover 10 Mb/s, 100 Mb/s and 1 Gb/s Ethernet; the hardware provides one 10 GbE port and two 1 GbE ports for up to ten gigabits on a single link.

What rack depth and clearance does the 1.74 in high chassis require?

The unit measures 29.0 x 16.93 x 1.74 in and weighs 18.69 lbs, fitting a standard 1U rack space with at least 16.93 in of usable depth.
