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 & 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.
