QNAP Hgst WD Ultrastar DC HC 320 6TB - 72113600-6050400-000-RS

QNAP 72113600-6050400-000-RS 4-Bay 1U Rack NAS

The QNAP 72113600-6050400-000-RS is a 1U rack-mount network-attached storage unit built around a Marvell 6281 800MHz processor with 512MB of DDR2 RAM — a compact, low-footprint appliance designed for small-to-midsize deployments where rack space is at a premium and dedicated storage is needed without the overhead of a full server platform. The unit ships without drives, giving you the flexibility to populate it with the HGST/WD Ultrastar DC HC320 6TB drives or other compatible SATA I/II HDDs based on your capacity and workload requirements.

Overview

This NAS sits in 1U of rack space and supports four 3.5-inch or 2.5-inch SATA I/II drives — a mix that lets you deploy either standard desktop-class HDDs or 2.5-inch SSDs depending on your performance and budget priorities. The Marvell 6281 running at 800MHz handles the core file-serving and storage management tasks without the power draw or thermal footprint of an x86 platform, which matters in densely populated racks or environments with limited cooling capacity. The 16MB of onboard flash holds the firmware independently of the data drives, meaning a drive failure does not take down the operating system.

Key Features

• Marvell 6281 800MHz CPU: An ARM-based processor purpose-built for NAS workloads — efficient under sustained read/write loads typical of multi-user file sharing or surveillance storage without the idle power consumption of a general-purpose x86 chip.
• 512MB DDR2 RAM: Provides adequate headroom for the NAS operating system and concurrent file-serving tasks. In a surveillance context, this supports simultaneous stream writes from multiple cameras without memory contention causing dropped frames to storage.
• Four SATA I/II Drive Bays (3.5" or 2.5"): Accommodates up to four drives in a single 1U chassis. With 6TB drives per bay, you can reach 24TB raw capacity in this footprint — enough for extended retention on moderate multi-camera deployments without adding a second unit.
• 16MB Onboard Flash: Firmware lives on dedicated flash storage separate from the data drives. This means OS integrity is maintained regardless of drive health, and firmware updates or recovery procedures do not put recorded data at risk.
• 1U Rack Form Factor: Installs directly into a standard 19-inch equipment rack alongside NVRs, switches, and patch panels. In security closets or IT racks where every unit of space counts, a 1U footprint is a meaningful advantage over tower-style NAS units that require shelf space.
• Ships Without HDD: Drive-free shipping lets you specify exactly the storage density and drive model you need. Pairing with the HGST WD Ultrastar DC HC320 6TB drives (sourced separately) gives you enterprise-class, vibration-compensated HDDs rated for 24/7 operation — the right class of drive for continuous surveillance write workloads.

Integration & Compatibility

The four drive bays support SATA I/II HDDs and SSDs in both 3.5-inch and 2.5-inch form factors. QNAP maintains a compatibility list for validated drives — cross-reference your drive model before populating the bays to confirm tested support. The TS-410U platform (which this unit is based on) is designed to integrate into standard rack environments alongside network video recorders and PoE network switches, functioning as supplemental or primary storage depending on your VMS architecture. For buyers evaluating the broader QNAP storage line, this unit targets the entry-to-midrange rack segment; higher-channel or higher-throughput deployments should consider current-generation QNAP NAS units with faster processors and expanded memory. Review the NAS storage category for current-generation alternatives if your workload demands exceed what an 800MHz ARM platform delivers at sustained concurrent load.

Frequently Asked Questions

Q: Does the QNAP 72113600-6050400-000-RS include hard drives?

A: No. The unit ships without HDDs. You populate the four bays with compatible 3.5-inch or 2.5-inch SATA I/II drives of your choosing. The product name references the HGST WD Ultrastar DC HC320 6TB as the intended drive pairing.

Q: What drive sizes does the 72113600-6050400-000-RS support?

A: The four bays accept both 3.5-inch and 2.5-inch SATA I/II hard drives or SSDs, giving you flexibility to mix form factors based on capacity and cost requirements.

Q: What processor and memory does the 72113600-6050400-000-RS use?

A: It runs a Marvell 6281 ARM processor at 800MHz with 512MB of DDR2 RAM and 16MB of dedicated flash memory for the firmware.

Q: How much rack space does the 72113600-6050400-000-RS require?

A: The TS-410U-based unit occupies 1U in a standard 19-inch equipment rack.

Q: Is the 72113600-6050400-000-RS suitable for 24/7 surveillance storage?

A: The chassis supports continuous operation and can accommodate up to four NAS/surveillance-rated drives. Use drives rated for 24/7 workloads (such as the WD Ultrastar DC HC320 referenced in the product name) rather than desktop-class HDDs, which are not designed for always-on write loads.
