Can I also use one in my computer?

TL;DR: Yes, you may use this card in your computer, but you will need to locate the correct driver. 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

Any alternative 10gb cards for ds1621+/ds1821+? because honestly those synology are priced way too high.

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

Does this work with my Synology DS418j?

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.

Easy install and works.

So far this network adapter has worked well in my DS1819+. 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!
