What this NAS is and who it fits

The Buffalo Technology TS5420DN1602 is a four-bay desktop network-attached storage device that arrives with 16 terabytes of NAS-grade drives pre-installed and RAID pre-configured. It targets small-business teams or advanced home users who need a ready-to-run, high-capacity file server without sourcing drives separately.

Practical limits of the network interface

The unit provides one native 10-gigabit Ethernet port and two 1-gigabit Ethernet ports, all using RJ-45 connectors that work with standard Cat 6a or better cabling. Aggregate throughput will be bounded by the 10 GbE uplink, so environments that require multiple concurrent 10 GbE links will need additional infrastructure.

The spec that decides fit

The Annapurna Labs Alpine AL524 quad-core processor running at 2.04 GHz paired with 8 GB of DDR4 memory determines whether the NAS can sustain your workload. Buyers who need heavier virtualisation density or larger metadata caches should verify that this CPU and memory combination meets their performance threshold.

Domande su questo articolo

Should I choose the 16TB model or a different capacity for my storage needs?

This model ships with 16TB configured as 2 x 8TB drives in four bays, leaving two bays free for future expansion.

What does the 10GbE port deliver in actual file-transfer speed?

The native 10GbE port enables high-speed transfers without cable upgrades, limited by drive throughput and network conditions.

How does the SATA interface limit performance with the included drives?

The four SATA bays connect the 8TB drives; maximum throughput is governed by the SATA link and the AL524 quad-core processor.
