Perfect for 10GbE network
For a 10Gb upgrade on a Synology RS1219+ NAS the E10G18-T2 works very well. It heats up much less than its little brother.
Thanks to these two connectors, it is possible to connect a 1GbE switch and a 10GbE Lan PC at the same time. Maybe one day I will do link aggregation.
Today it essentially allows me with the implementation of an iSCI disk, to use its nas as an application/game host without needing SSD/NVME cache (iSCI mounted on a raid 0 partition). No more lag while watching 4k movies! So I kicked my disks out of my tower, changed my enclosure from a 75L -> 15L.
I'm not sure if it's a good idea to buy a new one, but I'm sure it's a good idea to buy a new one.
