Consistently fast caching for 24/7 environments
Built for system cache, the Synology SNV3510 SSD pushes up random I/O performance and reduces latency in demanding 24/7 environments.
It offers durable caching with over 225,000/45,000 4K random read/write IOPS and a 491 TBW endurance rating, suitable for multimedia post-production and database applications.
Data integrity safeguards
SSD cache boosts your system’s read/write performance by storing transient data in solid-state drives to increase retrieval efficiency and cut down recurring requests to the primary storage. Data integrity is important, as cached data is continuously relocated.
The Synology SNV3510 integrates end-to-end data protection to safeguard data integrity over the entire transfer path. The SNV3510 comes with power loss protection circuit design, further preventing data corruption during an abnormal shutdown.
Dedicated capacitors provide power to flush data-in-flight into NAND flash in a power loss event, and firmware is designed to enable a correct restart on the next power-up.
Lifetime analytics based on actual workload
Full integration with Synology’s DiskStation Manager (DSM) enables lifetime analytics for each SNV3510 based on actual workloads:
- Timely Notifications
Plan further ahead for uninterrupted system performance and longevity with timely notifications.
- Optimal Use
Easy monitoring allows you to make optimal use of each SSD.
Purpose-built for Synology NAS
Firmware versions and component changes can over time cause SSD compatibility issues. The Synology SNV3510 is thoroughly tested for compatibility with Synology’s systems following each engineering change, while firmware and component changes are strictly managed.
Intensive I/O stress, power cycling, and temperature trials ensure that this SSD meets Synology’s strictest standards for quality and reliability (please see accessories tab for compatible NAS units).
