Warranty5 years limited

Best for

  • SSD cache to accelerate HDD volumes in Synology NAS without using a 3.5" drive bay
  • Multi-user file servers, database storage and virtualisation workloads
  • Adding NVMe cache to supported Synology systems via an M2D20, M2D18 or E10M20-T1 card

Key features

1600 GB capacity in an M.2 2280 form factor with an NVMe PCIe 3.0 x4 interface.

Up to 3,000 MB/s sustained sequential read and 1,000 MB/s sequential write (128 KB, QD32) in Synology's testing.

Up to 660,000 / 120,000 sustained 4K random read/write IOPS in Synology's testing.

Rated for over 2,900 TB written (JESD219A enterprise workload) with an MTBF of 3 million hours.

Power loss protection: dedicated capacitors flush data in flight to NAND flash during a power failure, and the firmware enables a correct restart on the next power-up.

Lifetime analytics in DSM estimate remaining life from the drive's actual workload and send timely notifications.

Firmware updates install through Synology DSM, with firmware and component changes strictly managed by Synology.

Validated for Synology systems with I/O stress, power cycling and temperature testing after every engineering change.

Fits Synology internal M.2 slots and the E10M20-T1, M2D20 and M2D18 adapter cards.

The Synology SNV5420-1600G in depth

Built for NAS caching

The SNV5420-1600G uses the NVMe PCIe 3.0 x4 interface in a compact M.2 2280 module, so it adds SSD cache without taking a 3.5" drive bay. Synology rates it for up to 660,000/120,000 sustained 4K random read/write IOPS, which helps cut latency for frequently accessed data in 24/7 multi-user systems.

Endurance and data integrity

The drive carries a >2,900 TB TBW rating calculated on a JESD219A enterprise workload and an MTBF of 3 million hours. End-to-end data protection guards data across the transfer path, and power loss protection capacitors write cached data to NAND flash if power fails.

Managed from DSM

Synology DSM provides lifetime analytics based on actual workload, timely health notifications and firmware updates, so drives stay current without separate maintenance sessions. Synology covers the drive with a 5-year limited warranty.
