QNAP TS-351 Overview

The TS-351 3-Bay NAS Enclosure from QNAP combines media center functionality with efficient auto-tired storage and RAID functionality to provide improved data protection, system performance, and storage utilization. With the ability to stream and share photos, music, and videos throughout your home and beyond using HDMI, the TS-351 and its minimalist design can fit into your workspace as a digital hub.

The TS-351 is powered by a 2.41 GHz Intel Celeron J1800 Dual-Core processor and 4GB DDR3L RAM, which can be upgraded to 8GB by using one 4GB module in each of the two SO-DIMM slots. Network connectivity is achieved using the Gigabit Ethernet port. This NAS also supports JBOD and a variety of RAID modes, including RAID 0, 1, and 5, each of which offers data redundancy, speed, or a combination of both.

This 3-bay enclosure has the ability to natively house both 3.5" SATA hard drives, as well as 2.5" hard drives and SSDs using an adapter. Of the three 3.5" bays, two support SATA II 3 Gb/s and one supports SATA III 6 Gb/s. There are also two M.2 NVMe PCIe M.2 2280 slots for SSD caching and auto-tiering to help continually optimize storage efficiency across M.2 SSDs, 2.5" SATA SSDs, and high capacity HDDs. Non-encrypted read speeds can reach up to 113 MB/s and write speeds max out around 112 MB/s, while using encryption still delivers read speeds of up to 103 MB/s and write speeds of up to 89 MB/s. Using its one 5 Gb/s USB 3.0 Type-A port and two USB 2.0 Type-A ports, this QNAP NAS can be connected to other QNAP devices, as well as other external drives and peripherals. Additionally, the TS-351 is validated with FIPS 140-2 AES 256-bit encryption, helping to prevent sensitive business data from unauthorized access and breaches.

QNAP's TS-351 runs using a 65W power supply that operates using 100-240V. It is compatible with Windows, Mac, Linux, and UNIX. Included is an Ethernet cable, a power cord, an AC adapter, and two M.2 SSD heatsinks. Protection is provided by a limited 2-year warranty.

General Features

Dual-Core High Performance

The TS-351 is designed for home and small offices, allowing you to effortlessly manage files and enjoy multimedia entertainment while also providing reliable data protection. It uses a 2.41 GHz Intel Celeron J1800 Dual-Core processor (burst up to 2.58 GHz) and 4GB of DDR3L memory (upgradable to 8GB), provides 3.5" SATA II 3Gb/s and SATA III 6 Gb/s drive bays, and supports AES 256-bit encryption for both full NAS volumes and shared folders, ensuring system performance while protecting the confidentiality of sensitive business data stored in the NAS.

Elegant Appearance, Effective Airflow

The TS-351 sports a stylish and elegant look with an industrial design concept to provide effective airflow and better cooling, ensuring smooth performance even under the heavy loads. The tooless 3.5" hard drive installation allows easier system setup and maintenance, while the front-panel LEDs assist in viewing system status.

M.2 SSDs for Cache Acceleration or Efficient Tiered Storage

The TS-351 supports SSD caching, and features two M.2 slots that support M.2 PCIe (Gen2 x1, up to 500 MB/s) NVMe SSDs with 2280 form factors (sold separately) for boosting the overall workflow of intensive, IOPS-demanding applications. Moreover, Qtier technology empowers the TS-351 with auto tiering that helps continuously optimize storage efficiency across M.2 SSDs, a 2.5" SATA SSD, and high-capacity HDDs with around-the-clock acceleration. Qtier 2.0 features IO-awareness that empowers SSD-tiered storage with a cache-like reserved space to handle burst I/O in real time, greatly maximizing the advantages of SSD.

Optimized SSD Performance with Over-Provisioning

With SSD prices continuing to become more affordable for home and small business users, there's never been a better time for using SSDs in your NAS to enjoy higher performance, faster file backups, smoother multimedia experiences, and optimized virtualization applications. The QTS 4.3.5 OS takes SSD functionality even further by supporting software-defined SSD RAID extra over-provisioning (OP) that enables you to allocate additional OP space from 1% to 60%, beneficial for optimal SSD random write speeds and extended lifespan with higher endurance. Now you can use affordable consumer SSDs for the TS-351, adjust the SSD OP, and potentially attain performance and endurance levels similar to enterprise-grade SSDs.

Snapshots Protect Your Data Against Ransomware

Snapshots help protect your data by fully recording the NAS system state and metadata. Use Storage & Snapshots Manager or File Station to easily manage snapshots and quickly restore the system to a normal state if an error occurs. QNAP snapshots are block-based and only record the changed data. Not only does this save storage space but also reduces the time required to back up and restore data. The TS-351 can support up to 256 snapshots per NAS and 256 snapshots per volume/LUN.
