Know before you buy
The SNV3400 is specifically engineered as a cache drive for Synology NAS systems. By storing frequently accessed data on this high-speed NVMe drive, it significantly reduces latency and boosts overall system performance in multi-user environments.
No, this drive is designed for specific Synology NAS models that feature built-in M.2 NVMe slots. You should check the official Synology compatibility list for your specific NAS model before purchasing to ensure it is supported.
While it is technically a storage drive, it is optimized for the high-intensity, constant read/write cycles of caching. Using it for general storage is possible, but its 400GB capacity is relatively small compared to traditional hard drives, making it best suited for performance acceleration.
The SNV3400 is built for enterprise-grade reliability with a 500 TBW (Terabytes Written) endurance rating and a 1.8 million hour MTBF. It is specifically rated for 24/7 operation, meaning it is designed to handle the constant data shuffling required in a busy NAS environment.
You can expect sequential read speeds of up to 3100 MB/s and sequential write speeds of 550 MB/s. These speeds are optimized to handle the random I/O demands typical of NAS caching tasks.
Yes, the Synology SNV3400 includes a limited 5-year warranty. This provides long-term peace of mind for a component that will be running continuously in your storage system.
