5 Things to Know About the Synology DS1522+ Storage and Caching Setup
Regarding the Synology: 1. The DS1522+ uses SATA drives for main storage Its five bays accept 3.5-inch and 2.5-inch SATA drives for your primary storage pool.
NVMe slots are for caching only The two M.2 NVMe slots are reserved exclusively for SSD caching, not for storage volumes.
You cannot use NVMe drives as storage in DSM The architecture prevents those NVMe drives from appearing as usable storage volumes in DiskStation Manager.
This separation keeps performance clean By isolating caching from storage, the system avoids mixing workloads and keeps data management straightforward.
Plan your SATA drives for capacity Since NVMe slots don’t add storage, all your data capacity must come from the SATA bays.
