Key Features
Choose the supported storage role
SNV5420 can serve as SSD cache or an M.2 storage pool where the NAS and DSM version support that role. Drive compatibility alone does not establish storage-pool support.
Capacity-specific performance
Sequential read reaches up to 3,000MB/s across all capacities. Sequential write reaches up to 650MB/s for 400GB and 1,000MB/s for 800GB and 1.6TB. Actual throughput depends on the host and workload.
Protect data in transit
Power loss protection helps preserve data during a power interruption, while health monitoring supports maintenance planning.
Fit the right system
All three SNV5420 capacities are supported in DS1825+, RS1226+ and RS1226RP+. Confirm the supported storage role and installation method before ordering. Contact ACE for help with other NAS models or adapter-card installations.
Summary
Choose SNV5420 capacity and endurance according to your NAS workload. Its M.2 design, power loss protection and integrated monitoring suit supported Synology flash configurations.
Synology SNV5420 Enterprise Series M.2 NVMe SSD
Synology SNV5420 SSDs use an M.2 2280 form factor and NVMe PCIe 3.0 x4 interface. This listing contains three SNV5420 capacities with different write, random-I/O and endurance ratings. The values below describe sustained drive performance under manufacturer test conditions rather than guaranteed NAS throughput. Host compatibility, DSM version and the installation method determine whether SSD caching or an M.2 storage pool is supported. Confirm those requirements before installation.
