D-Link DGS-2208 8-Port 10/100/1000 Desktop Switch Review

This is an unmanaged switch, which means that you can not configure Virtual Local Area Networks (VLANS) or Quality of Service (QoS) - though QoS is supported through the implementation of 802.1p, but all the attached devices must support 802.1p in order to use it. Since there is no configuration, all you have to do is plug it into power and plug your devices into it. It really is that simple for any unmanaged switch. It will automatically allow all your devices to talk to each other at the physical layer. Of course, your applications must be configured right to talk to each other, but these unmanaged devices make building the infrastructure a snap.
In answer to a previously posted review, I tested this device in the following way:
-Port 1 connected to my desktop computer with a Gigabit network interface card (NIC)
-Port 2 connected to a 10/100 switch which was connected to a gigabit ethernet storage device
-Port 3 connected to a second DGS-2208 switch which was connectedto the exact same model gigabit ethernet storage device
-Port 4 connected to a laptop with a 10/100 NIC
The point of this setup was to use the identical computer communicating with identical devices through a 10/100 connection and through a gigabit (1000) connection. I transferred a 10 GB file to the ethernet storage device through the gigabit connection first and then I transferred the exact same file through the 10/100 connection. The GB connection was about five times faster.
Now, this proves that the switch does not automatically throttle back to the slowest "connected" device. However, it does not indicate whether the gigabit connections will slow to the speed of 10/100 connections if those slower connections are actually active.
To test this, I transferred the same file from the laptop to the slower connected ethernet storage device while also transferring the file from the desktop to the faster connected ethernet stoarage device. The results? The gigabit connected devices still transferred the data at rates faster than possible on a 10/100 connection. This proves that the gigabit speeds are still achieved even when a 10/100 connection is active.
In the end, due to memory and processor limitations, this device cannot even compare to enterprise-class gigabit switches from Cisco and other providers; however, it is the best performing gigabit switch I've ever seen for under $75.

Recently we have installed network storage devices, and started to run backups and multi-media services on our home LAN (local area network). As a result the load on our network increased substantially. We decided to upgrade from fast ethernet to gigabit. Due to the arrangement of devices, we have several 8 port switches connected to a larger 24 bit switch which I guess is the backbone of our LAN.
When shopping for gigabit switches, the Trendnet 8 port gigabit greennet switch came up as not only a low cost, but also a low power switch. We purchased several and have been using them for almost half a year.
These switches are silent (there is no fan), and very low power (on my Killowatt meter they always show 0 watts), and very fast. They have limited support for jumbo packets (I forget the exact number, but its around a jumbo packet size of 7-9K).
This is a good solution as a low power, silent, gigabit switch that runs cool and is low cost. The switch is unmanaged, but does have status indicator lights. You will see if you are getting fast ethernet or gigabit speeds on each port. We have had no trouble with these switches.
