Choose the SA3410 if you want a newer, much more scalable platform: it has a newer CPU, far more RAM headroom, 12 bays with expansion support, built-in 10GbE, and M.2 slots for cache. The RS3411XS is an older 4-bay x86 unit with lower CPU/RAM limits and no M.2, so it’s the better pick only if you specifically want the older rack form factor and don’t need much growth.
