Ready-to-use 4-bay NAS with 32 TB

The TS5420DN3204 ships with four pre-tested 8 TB NAS-grade drives and a RAID array already configured so small-business teams can start storing files immediately. An Annapurna Labs AL524 quad-core processor at 2.04 GHz and 8 GB of DDR4 memory handle simultaneous backups, virtualization workloads and cloud sync jobs without extra setup.

Straightforward rack or desktop deployment

Four SATA bays accept the included OP-HD8.0N drives using tool-less trays while two USB 3.0 and two USB 2.0 ports provide quick external expansion. The single 10 GbE RJ-45 port works with existing Cat 6a cabling, but buyers who need more than one 10 GbE link or additional 1 GbE ports must add a separate switch.

10 GbE and SATA set the throughput ceiling

Sequential transfers top out at the 10 GbE line rate, while the four SATA channels limit sustained RAID rebuild and parity calculations to the drive media speed. The 8 GB DDR4 is soldered and cannot be expanded, so memory-heavy applications such as large Docker stacks or heavy database caches will hit a hard cap.

Questions about this item

How can I confirm the TS5420DN3204 is operating correctly after initial setup?

Check that the front Power LED is solid on and each of the four HDD LEDs shows steady activity without red alerts; the management console should report all four 8TB drives healthy and the selected RAID level active.

What ships with the TS5420DN3204 and what must I purchase separately?

The unit arrives with four pre-installed 8TB NAS-grade drives (32TB total), 8GB DDR4 memory, a power cord, and rack-mount brackets; no additional drives or memory modules are required for basic operation.

Which capacity version of the TeraStation 5020 series should I choose for a small business needing 32TB raw storage?

The TS5420DN3204 provides exactly 32TB (4 x 8TB) in a 4-bay desktop chassis; select this model when 32TB matches your capacity plan and you want drives included and RAID pre-configured.
