Greater performance. Utmost speed.
Write Coalescing drives random write performance for all-flash arrays
Write amplification is an undesirable effect of SSDs, bringing challenges to flash memory performance and endurance. QNAP’s exclusive Write Coalescing algorithm 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 can also improve SSD lifespans.
Inline data compression and compaction improves write speeds
Inline data compression shrinks file sizes to lower storage I/O workloads for improved performance. It also helps optimize storage utilization of SSD over-provisioning.
TRIM improves performance of SSD data writes
While almost all SSDs have shown consistent write performance degradation, TRIM helps overcome write performance drops. SSD TRIM allows the system to inform SSDs to delete unneeded data blocks. Deletion tasks are processed during system idle times, meaning it does not have to wait for when new data is written to the block.
Pool over-provisioning ensures write performance
With Pool Over-provisioning, space can be flexibly reserved in a storage pool to allow new data to be written into a complete block even if the pool is almost full, thus improving the performance of fragmented pools. For write-intensive workloads and performance-demanding applications (such as SQL transaction logs, backups, surveillance, and medical videos) you can set higher pool over-provisioning to attain higher write performance.
Optimized performance for VMware virtualization with iSER
QNAP NAS supports the iSCSI Extensions for RDMA (iSER) protocol. When used with an iSER-compatible 10GbE/40GbE network card, iSER boosts the data transfer performance of QNAP NAS as VMware® ESXi storage and reduces the CPU load of the ESXi server, providing an essential tool to optimize demanding virtualization applications. All-flash storage featuring iSER can obtain significant performance increases in VMware® virtualization environments.
Higher endurance. Maximized cost efficiency.
Software-defined SSD optimization for higher reliability and lifetime
QNAP’s cutting-edge "software-defined SSD extra over-provisioning" technology transforms your NAS into SSD-aware storage. Users can allocate an additional over-provisioning ratio for SSD (from 1% to 60%) to prevent performance degradation caused by write amplification. Moreover, the lower the write amplification, the higher reliability and lifetime you can attain from SSDs.
Note: QuTS hero does not support software-defined SSD extra over-provisioning for an individual SSD.

Efficient data reduction benefits SSD write endurance
Inline data deduplication is block-based and runs before data is written to storage. Coupled with inline compression technology, the data size is significantly reduced and thus decreases the amount of SSD writes. This greatly optimizes all-flash storage usage while improving both write performance and SSD lifespan.
Easy Integration with Fibre Channel SAN solution
Storage Area Networks (SAN) deliver reliable high performance, making it a preferable storage option for environments that require low-latency and fast data transfer. By using a QNAP 16Gb/32Gb Fibre Channel card, a QNAP all-flash NAS can be easily added to existing SAN environments at an affordable price point. Coupled with the QuTS hero operating system, the QNAP all-flash NAS’s powerful hardware is further enhanced with exceptional IOPS performance, powerful data reduction capabilities, self-healing against silent data corruption, and comprehensive backup/restoration features.
