The Netgear ProSafe GS105 V4 is a 5 port gigabit switch that consumes at most only 3.5 watts! Although we generally focus on fairly high-end components, sometimes you just need to aggregate a few ports. With wireless networks being ubiquitous at this point, and more devices being optimized for mobile, sometimes one simply needs to add a small switch. One great example of this is if one has a pfsense appliance or a typical SOHO router/ switch and WiFi access point, but only a few switch ports. Something like the Netgear ProSafe GS105 v4 works wonders. Let’s take a look at what this $30 five port gigabit switch has to offer.
The front of the Netgear ProSafe GS105 V4 is very simple. There are five RJ-45 ports dominating the front of the switch. These three ports can run in 10mbps, 100mbps and gigabit (1,000mbps) modes. One LED for 10M, one LED for 100m and both for gigabit. There is also a power LED on the front of the chassis so one knows that the unit is powered on.

Looking to the rear of the Netgear ProSafe GS105 gigabit switch one can see a simple Kensington locking point and a power supply input. It should be noted that the average Kensington lock is going to cost more than this switch, but sometimes the time and effort to replace makes a lock important. For those wondering, the effective dimensions of the unit are a bit larger then the dimensions listed in the quick specs once cables and the power input are taken into account. It would be great if Netgear could find a way to put the power cable on the same side as the Ethernet ports in a V5.
One will also notice that the sides are ventilated. The Netgear ProSafe GS105 does not have a fan which helps a lot in two areas. First, it is completely inaudible. Second, adding a fan would likely ad 50% to 100% more power consumption. Heat was never an issue with the Netgear GS105.
In terms of performance, the Netgear ProSafe GS105 does not offer management capabilities and is therefore a very simple gigabit Ethernet switch. Performance wise, nothing to get excited about and in our testing all five ports ran fine. Streaming HD video was not an issue and performance between nodes was in the 100-125MB/s range for data transfers.
Overall the Netgear ProSafe GS105 does well for what is made for, to be a small, quiet, power efficient switch. At about $30 after rebates, the Netgear GS105 is very inexpensive. If one does need management capabilities, Netgear has a version of the GS105 called the Netgear GS105e which has some management functionality built-in for around $45. The nice thing about these low-end Netgear switches is that they run cool and are very reliable. I have one 8-port ProSafe GS108 switch that now has 15 months of consecutive uptime. There is surely something to be said for inexpensive and reliable switches.
