Long answer: Synology re-brands an OEM card, and you can search for those OEM drivers. The reason this card exists is so Synology can mark-up the price, as they only support their own brand in their NAS products. Some people are obsessed with protecting warranty compliance, particularly in the business world. So you would be better served finding another card. Good luck **Q: Any alternative 10gb cards for ds1621+/ds1821+? because honestly those synology are priced way too high.** A: If you want both 10G network and M.2 slots, this E10M20-T from Synology with NOT work in the DS1817+ I am positive, and I suspect it would not work in the DS1621+ either....but if you go to synology website, it lists the compatible systems that it works in right there in the specs for the card. Unfortunately, I did not read that before hand...so I bought this for my DS1817+, but the m.2 slots don't work (the 10g port does though). If you want just 10g network ports...the X540-T2 works perfectly in my ds1817+ and ds1821+; you don't need the Intel version either. I have the 10Gtek version I bought here on Amazon and it works perfectly. No need to buy the Synology brand. https://www.amazon.com/dp/B01HMGWOU8?ref=ppx_yo2ov_dt_b_product_details&th=1 **Q: Will this card work in a DS1621+?** A: yes **Q: Does this work with my Synology DS418j?** A: It is not listed in the optional accessories section of DS418j in the product specs page. So I bet it will not work or it is not possible to attach one. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It works as advertised. 10Gbe connection for Synology supported NAS *by S***T on 12 January 2024* Confirmed 10Gbe on both ports ### ⭐⭐⭐⭐⭐ Highly recommended upgrade! *by E***P on 8 April 2026* Super easy to install. Highly recommended upgrade for compatible Synology NAS.

Was very easy to install and just worked. No drivers to install or tinkering. Installed the card and plugged in the cat 6 cable and done! Confirmed 10gb speeds to my pcs. Haven't had any drop outs or speed issues so far. That said I have only had it for a month so I will update review if issues do arise. Otherwise its a great add on for your Synology Nas if you could use 10gb speeds! ## Frequently Bought Together - Synology 10Gb Ethernet Adapter 1 RJ45 Port (E10G18-T1) - TP-Link TL-SX105 | 5 Port 10G/Multi-Gig Unmanaged Ethernet Switch | Desktop/Wall-Mount | Plug & Play | Fanless | Sturdy Metal Casing | Speed Auto-Negotiation - TP-Link 10GB PCIe Network Card (TX401)-PCIe to 10 Gigabit Ethernet Adapter,Supports Windows 11/10/8.1/8/7, Servers 2019/2016/2012 R2, and Linux, Including a CAT6A Cable --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/257379865-10gb-ethernet-adapter-1-rj45-port-e10g18-t1](https://www.desertcart.co.za/products/257379865-10gb-ethernet-adapter-1-rj45-port-e10g18-t1) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-21*
