SSD Synology SNV5420-800G

The SNV5420‑800G is designed for demanding workloads in Synology NAS systems. This M.2 2280 NVMe SSD uses a PCIe 3.0 x4 interface and achieves sustained read speeds up to 3000 MB/s and write speeds up to 1000 MB/s. Random I/O performance reaches up to 400,000 IOPS for reads and 70,000 IOPS for writes.

With a rated endurance of 1400 TBW and an MTBF of approximately 3 million hours, it's built for longevity. It includes power-loss protection to safeguard cached data in case of sudden shutdowns. Typical power consumption is 5 W during reads, 5.5 W during writes, and 2.5 W at idle. Certified to operate between 0 °C and 85 °C.

The SSD integrates seamlessly with Synology DSM, offering smart wear analytics, health monitoring, and automatic firmware updates for consistent performance and reliability.
