Synology FlashStation (FS Series) NAS Memory

Registered ECC memory for Synology FlashStation — the FS2500, FS3400, FS3410, FS3600 and FS6400 all-flash NAS platforms.

FlashStation is built entirely on SSDs, and that changes where the bottleneck sits. With no seek latency to absorb, throughput is limited by the controller and by how much the array can hold in cache — which means memory determines what the flash can actually deliver. On these units RAM is not a comfort upgrade; it is the difference between an all-flash array performing like one and performing like a fast disk array.

All modules here are DDR4-2666, in registered ECC RDIMM for the FS3400, FS3410, FS3600 and FS6400, and ECC UDIMM for the FS2500 — which shares its D4EU01-16G part with the RackStation RS2423+ and RS2423RP+. 16GB and 32GB densities.

ECC is not optional at this tier. These arrays hold live business data with integrity protections that assume the memory holding it is sound, and Synology specifies ECC accordingly.
