This review is from: D-Link GO-SW-8GE Smart 10/100/1000Mbps 8-Port Gigabit Metal Desktop Switch
This is a great switch. It is solidly built, and has a bit of weight to it so the cords don't pull it around, yet it really is tiny. It even has mounting slots on the bottom so you can secure it to a wall or table if you choose to.
Testing a large (4gb) compressed file transfer between 2 high end UNIX servers yielded an average transfer rate of 106MB/s. Unfortunately, I didn't have 8 of these servers available to test all ports simultaneously, so I had to move my testing over to 8 core i3 Windows boxes running Windows 7 Pro. These didn't perform quite as well, but still produced outstanding results using direct memory copies across the switch. Regardless of whether I tested 1, 2, 3, or 4 simultaneous transfers, each yielded an average throughput of about 91.5MB/s, or a combined switching capacity of 732MB/s. I am sure these numbers would be higher if I had used more powerful Windows computers.
I left all 8 ports connected and shuffling data around for over a week without a single dropped connection or error reported.
It was also very handy that the wall-wart power supply supports 100-240V.
Keeping in mind that the theoretical maximum throughput of a 1 Gbps connection (without using jumbo packets) is 124.5MB/s, this little gem is a great performer, and at $40, I don't see how you can go wrong.
Just for laughs, I repeated the same test with the same 2 UNIX servers in my first test on a single gig blade in a Cisco 6509 enterprise switch, and got throughput numbers in the 85MB/s range. Remember this switch ran at 106MB/s for this test...
