8-port vs 5-port 2.5G switch for a closet lab

Count the real endpoints — router LAN, NAS, desktop, AP backhaul, mini PC — and add two. That number picks the box.

Do not reprint the four-SKU closet table. If you already know you want eight copper ports and no SFP+, buy from the 8-port roundup. This page is only the port-count decision. All six boxes below are fanless and have no PoE. Netgear's 8-port lists 0 fans and 7.98 W max. TEG-S380 V2 max is 7.26 W.

Skip

Skip 5-port leftovers with one 2.5G uplink and four 1G ports. Skip SODOLA / HASIVO toys. Skip buying five ports "to start" if the AP and the mini PC are already in the cart. Two unused 2.5G ports cost less than a second switch later.
