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 heaviest loads. The tool-less 3.5-inch 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-inch SATA SSD, and high-capacity HDDs with around-the-clock acceleration. The new 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.
Note:
1. The 3rd drive bay of the TS-351 supports SSD caching. You can purchase 2.5-inch HDD/SSD drive tray bases from the QNAP Online Shop.
2. M.2 SSDs are sold separately. As M.2 SSD operations can easily generate excessive heat, it is recommended to install a heatsink on M.2 SSDs.

Enjoy optimized SSD performance with extra 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 latest QTS 4.3.5 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 and 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 with 4GB RAM can support up to 256 snapshots per NAS and 256 snapshots per volume/LUN.
