Hybrid structure for enabling SSD and tiered storage

SSD prices continue to fall, but creating a full-SSD storage solution is still out of reach for most users - especially if they require high-capacity storage. The TVS-951X provides the ability to use a hybrid storage structure that leverages the benefits of both hard drives and SSD to provide high storage capacity and high performance. You can flexibly allocate applications to SSDs, set up a SSD cache, or use Qtier™ technology to automatically tier your frequently-accessed files to the SSD for the highest access speeds. Users can take advantage of these features to fully optimize the storage utilization of the TVS-951X.

Protect data with snapshots

Snapshots help protect your data by fully recording the NAS system state and metadata. If a file is accidentally deleted or modified, you can use snapshots from the Storage & Snapshots Manager or the File Station to quickly restore the file to its previously-recorded state. 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 TVS-951X supports up to 256 snapshots per volume/LUN, and up to 1,024 snapshots in total.
