Which Synology NAS models support SSD cache?

Details

SSD caches can achieve better performance on Synology NAS by leveraging the advantages of SSDs. By storing frequently accessed data on an SSD cache, you can reduce I/O latency and improve system performance of your Synology NAS.

Most Synology NAS models support SSD cache. Installing SSDs according to the following ways allows you to create an SSD cache:

  • 2.5" SSDs installed in drive trays
  • M.2 SSDs installed in built-in M.2 SSD slots
  • M.2 SSDs installed using an optional M.2 SSD adapter card

The following tables list out the Synology NAS models that support SSD cache creation.
