About the Synology E10M20-T1 10GbE and M.2 NVMe SSD Combo Adapter Card
The Synology E10M20-T1 combines two upgrades on one PCIe 3.0 x8 card: a 10GbE RJ-45 port and two M.2 NVMe SSD slots. It suits Synology NAS owners who want faster network transfers and SSD caching but have only one free PCIe slot. The copper port works over standard Ethernet cabling and also negotiates 5, 2.5 and 1 Gbps, while the M.2 slots take 22110 or 2280 NVMe drives. Jumbo frames and checksum offloading are supported. Compatible systems include the DS1819+, DS2419+, RS2423+ and many SA and xs models, and the card carries a 5 year Synology warranty.
