In-line Compression Traditional storage Data Compression (LZ4 algorithm) Thin Provisioning with Space Reclaim

In-line Deduplication Deduplicated data is cached for much better performance by reducing disk access! Deduplication rates for VM deployments can range as high as 95% savings. A

Extend SSD Endurance by Data Reduction ZFS File System With Deduplication & Compression Features. The ZFS File System can be the best choice to pair with the SSD with its Deduplication and Compression functions by reducing the data size and pattern that need to be written to the D directly. Deduplicated Data Deduplication Compressed Data Wri te to SSDs as s equential as much as possib

Write Coalescing QES 2.1.0 features QNAP’s exclusive Write Coalescing algorithm that is engineered for flash optimization by transforming all random writes to sequential writes along with reduced I/O. It not only effectively increases random write performance for all-flash environments, but also can improve SSD lifespan.
