Features
Durable SSDs Built for Demanding Caching Workloads
Synology Enterprise Series M.2 NVMe SSDs are designed to handle demanding caching workloads in 24/7 high-concurrency scenarios. Their strong sustained I/O performance makes them ideal for systems used as highperformance file servers, database storage, and virtualization environments.
High Performance: Up to 660,000/120,000 sustained 4K random read/write IOPS[2]
Enterprise-Grade Endurance: Suitable for intensive caching workloads with up to 2,900 TBW[3]
Robust Data Protection: End-to-end data protection ensures data integrity
Lifetime Analytics: Stay on top of drive health with lifetime wear analytics and notifications[1]
Built for Synology Systems: Proven interoperability through rigorous validation and automatic firmware updates[4] through Synology DSM
Caching for Enterprise Workloads
Enterprise Series M.2 NVMe drives are engineered to deliver reliable, highspeed caching in demanding 24/7 environments, enhancing I/O performance and minimizing latency. With up to 660,000/120,000 4K random read/write IOPS[2] and up to a 2,900 TBW endurance rating[3], these drives offer a robust caching solution ideal for multi-user environments, all without occupying 3.5" drive bays.
Data Integrity Safeguards
SSD caching boosts system read/write performance by storing transient data in solid-state drives to increase retrieval efficiency and by reducing reoccurring requests to the primary storage. Data integrity is important, as cached data are continuously relocated. Synology Enterprise Series M.2 NVMe SSDs drives offer end-to-end data protection to safeguard data integrity over the entire transfer path. SNV5400 Series drives feature a power loss protection circuit design6 with dedicated capacitors. This system prevents data corruption during abnormal shutdowns by ensuring data-in-flight is safely written to NAND flash. Additionally, the firmware enables a proper restart upon the next power-up.
Real-World Workload Analytics
Full integration with Synology DiskStation Manager (DSM) operating system allows Synology systems to provide lifetime analytics[1] based on actual workloads. This enables easy monitoring, allowing users to track SSD usage and make optimal use of each drive. Additionally, the system provides timely notifications of drive health and remaining life, aiding system administrators in planning ahead for replacements to ensure uninterrupted system performance.
Purpose-Built for Synology Systems
Synology M.2 NVMe SSDs are rigorously tested for compatibility with Synology systems following each engineering change, with firmware and component changes strictly managed to ensure optimal performance and reliability. Firmware updates can be easily installed through Synology DiskStation Manager (DSM) with a single click.5 All products undergo intensive I/O stress, power cycling, and temperature trials to meet Synology's strictest standards for quality and reliability, guaranteeing consistent performance and compatibility.
[1]Lifetime analytics are available in DSM 6.2.3-25426 and above
[2]Performance measured using FIO on Linux with Queue Depth 32 (128 KB = 131,072 bytes; 4 KB = 4,096 bytes).
[3]The TBW specifications denote the baseline endurance levels for Synology SSDs and are calculated using the JESD219A enterprise workload.
