Synology E10G18-T1 - Network adapter - PCIe 3.0 x4 low profile - 10Gb Ethernet x 1 - for Disk Station DS1618, RackStation RS1219, RS2418, RS2818, RS3618, RS818,RJ-45; 1 port

Installed in DS1621+. Working like expected. No issues.

Expensive, but I went for a branded Synology adapter because I wanted to be sure it was going to work. On an 1819+ undo 6 screws holding the case on, undo the screw and slide up the clamp that secures the card at the top, slot the card in, slide down the clamp, do up the screw. That took less than 5 minutes. What took longer was getting the case refitted due to an arrangement where there's a couple of pins that slide into slots and it took quite a few tries to get it all lined up perfectly, at which point the case slid into position and I was able to do up the 6 screws again. Plug in a network cable and check in DSM and there's a shiny new 10GB interface.

Does exactly what it says on the tin with easy install into my NAS with just a few screws to remove.It's a little on the pricy side but I guess you're paying for convenience and an all in one unit.

Thank You

Put in my Synology and now I get much better transfer speeds, who would have thought it...

works fine as expected, able to achieve super high speeds

It works perfectly in a Synology DS3617xs. I really wish I'd read more detail though, as no WoL is a major omission and, for that reason specifically, I've knocked off 2 stars.
