Software-defined
SSD Extra Over-provisioning
Unleash the full advantages of SSD – better performance and higher endurance
Did you know…
SSD Write Amplification is an undesired phenomenon that reduces SSD constant write performance and endurance.
SSD Over-provisioning space helps handle the upcoming IO and conduct Garbage Collection.
The pre-defined over-provisioning amount or specified utilities given from disk vendors still lack the flexibility and manageability for IT staff to directly measure and deploy such solutions.
WHAT WE OFFER
Software-defined SSD awareness: Performance driven to cater your needs
With SSD prices continuing to fall, they are becoming an increasingly cost-effective solution for boosting NAS performance. But to make the most of their amazing potential, you not only need the right SSDs - but also the right NAS! QTS 4.3.5 transforms QNAP NAS into SSD-aware storage with cutting-edge "software-defined SSD extra over-provisioning" technology alongside advanced SSD caching. Given the favorable flexibility to adjust SSD over-provisioning, you can enjoy better SSD performance and endurance - allowing you to potentially attain enterprise-grade SSD performance levels from affordable consumer SSDs!
HOW IT WORKS
Improve write performance with SSD extra over-provisioning
While almost all SSDs have shown consistent write performance degradation, QNAP's software-defined SSD extra over-provisioning helps sustain optimized SSD performance. It supports major SSD RAID configurations to improve random write speeds, with a constant performance boost of more than 100% for IOPS-demanding applications.
YOU WILL ENJOY
Extend SSD lifespan with higher endurance
Write amplification is an undesirable effect of SSDs, bringing challenges to flash memory performance and endurance. QNAP's SSD extra over-provisioning helps you combat write amplification by increasing the reserved space to SSDs. The lower the write amplification is, the better the SSD endurance performs for higher reliability and lifetime.
CATER YOUR NEEDS
Add up to 60% over-provisioning
Besides vendor-defined over-provisioning (internal over-provisioning), QTS 4.3.5 provides greater flexibility to decide additional over-provisioning space to prevent significant performance degradation. You can set an over-provisioning ratio for SSD caches, Qtier pools, and static volumes (between1% and 60%) in addition to the vendor-defined value.
Note: Over-provisioning can only be configured when a storage space is created. It cannot be set for existing SSD caches or volumes.
YOU MUST TRY!
Identify the optimum over-provisioning ratio with the SSD Profiling Tool
The SSD Profiling Tool is a unique QTS app that allows you to test SSD random write performance with extra over-provisioning ratio from 0 - 60%. Given the over-provisioning evaluation result, you can determine your target write performance (IOPS) to acquire the recommended over-provisioning ratio.
