3 Things to Know About the Synology DS923+ PCIe Expansion
Regarding the Synology: 1. The DS923+ includes a PCIe Gen3 x2 slot for network upgrades This slot can accept a 10GbE or 25GbE network card, giving you far faster transfer speeds than the built-in Gigabit ports.
The x2 lane width limits maximum throughput Unlike the x8 slots on the DS1621+ and DS1821+, the x2 slot has a lower bandwidth ceiling, so you won’t get full performance from a 25GbE card.
Even a 10GbE card through x2 is a major upgrade It will still massively outpace the two built-in 1GbE RJ-45 ports for large file transfers.
