I'm after an un-managed 5-port 2.5GbE switch to hang off my main multi-Gb switch over at most 20m of CAT5. I've tested that the cable will support 2.5Gb by using a Pluggable USB3 NIC on my laptop. So far I've found suitable switches from QNAP, TrendNet, TP-Link and Zyxel. The TrendNet & Zyxel (and the QNAP to a lesser extent) appear to be badged versions of the same item. Has anyone had any experience with any of these or seen any comparative reviews?
