There really is not much not to like about the SIIG USB 3.0 hub as it does exactly what it sets out to do: give you more options. Plus, it comes with a generous 5 year warranty.

It is sad, but the fact still remains that no matter how new your system is, you are going to have at most two USB 3.0 ports. This may sound like a lot right now, but as more USB 3.0 devices come on the market, you soon are going to feel the pinch. To help alleviate this issue, powered hubs are coming back into vogue, such as this one from SIIG. Will you see a performance impact when pairing your portable drives with this USB 3.0 hub? Let’s find out.

First SuperSpeed USB Hub

This 4-port USB 3.0 hub is one itty bitty piece of kit.  While SIIG doesn’t list any official dimensions, it is about 2.5″ x 3.5″ x 0.5″. This is in my book classifies this as one heck of a compact powered hub. To really understand how small this hub is, a photo down below shows the hub compared to a deck of cards. While my photography skills do not do it justice, this hub uses the same rubber-like plastic materials that SIIG USB 3.0 drive dock uses. So while it may be small, it is going to stay where you put it and not slip and slide like some other hubs I have used in the past did.

As you can see, the layout of this 4-port USB 3.0 hub is a little on the odd side. The four ports do not line up one after the other along one side like many hubs layout. Rather you have three along one side and a single one at each end. The one all by its lonesome at first didn’t make any sense to me, but then I realized that SIIG also makes a seven port version of this hub and it all became clear. Both hubs share the same form factor and in case, the four-port version simply omits one side’s worth of ports.

The upside to having a single port all by itself is that even the largest of flash drives will not block any of the other ports. This certainly is something to consider, as not all devices have standard width. Though to be honest, even a Corsair Flash Voyager GTR  will not block access to the other ports even when plugged into the “middle” of the three ports. However, if you have one of those extra beefy 128GB version of the GTR, this end port will indeed be a veritable godsend.

As shown in the picture below, the SIIG hub uses a single VLI VL800 controller chip. To be precise, this is the “VIL” branded VI810 controller chip. In case you are wondering, “VLI” stands for VIA Labs Inc. This is a USB 3.0 hub controller with support for four downstream ports and supports the USB Battery Charging Specification. This means it can output much more amperage than a typical hub can. The specification also states a max draw of 1500mA on a standard USB 2.0 A cable during low bandwidth communications and 900mA when used in conjunction with High Bandwidth connections. While SIIG does not list the actual max power draw per port, a safe assumption is 900mA per port as this conforms to the USB 3.0 specification.

Real World Performance

Personally, I consider these results to be a tie as the difference is so minor as to be negligible. One-tenth or a couple of tenths of a megabyte per second is a slight difference, to say the least.

Power Usage Test

To see exactly how good this hub is at its claims of being able to safely power USB devices, I devised a simple little test for it: plug in a crapload of USB-powered hard drives! To this end I dug out my Seagate GoFlex Portable drive, a Vantec Nexstar 3 (2.5″ only model) with a Western Digital 500GB Blue hard drive in it, a Seagate Momentus 5400.4 250GB drive (and attached a GoFlex USB 2.0 cable to it) and a Corsair Voyager GTR. I then plugged them all in and copied files from one to the other all at the same time for maximum power draw. I can honestly say I was impressed as that is a lot of electricity for the hub to provide, but provide it, it did and without any complaints, I might add.


There isn’t much to dislike about this SIIG USB 3.0 hub. It is small and compact so it will not take up much room. Yet it has a secure grip and feels to it so it is not going to go slipping and sliding all over the place and will stay where you put it. While the form and aesthetics of this hub are very nice, what I really liked was the fact it does exactly what you want a hub to do: add more ports without introducing a performance penalty.

While it does share a single connection, this is a lot of bandwidth and should be more than you will need in the foreseeable future. As long as you don’t plan on populating and using all four ports at the same time with high bandwidth devices, then this is perfectly fine. USB 3.0 offers an extremely fat bus that can easily accommodate a bunch of devices at the same time.

When you add in features like the ability to safely power a whole bunch of equipment, it is my opinion you end up with a very good product. To my way of thinking, there really isn’t a downside to this hub besides its asking price. Even here, $59.99 is not that huge an investment. And if you are like me and hate to go digging around the back of your case looking for free port, the cost is certainly outweighed by the ease of use. The included USB 3.0 cable is easily long enough to allow you to plug it in and place it near the front of the case, on top of the case, or pretty much anywhere else that is more convenient for you.

    Bought the USB 3.0- 2.0 7 port hub and it is being returned tomorrow. Shows up in the device manager only. Under “my computer” does not recognize the device nor all the external drives i have plugged into it are shown. Using windows 8.1 Called their support line and only an answer machine.

  2. Really? Four ports sharing the bandwidth is a negative? Isn’t that the definition of a hub? Requires a power receptacle? Isn’t that the definition of powered?

    I have purchased TWO of the (mistated) SIG 7-port usb 3.0 hubs. Imo, they are AWFUL. They have been ‘proven’ to be the CAUSE of blue-screens in my HP 8740w laptop (16gb RAM; 8-processors). The laptop will NOT boot up (past the HP logo screen) when (either of) the hub(s) are attached (although they can be (re)attached AFTER boot-up). In the first 3-4 months after I got them, (true) usb 3.0 drivers were NOT available — & they (at best) ‘dumbed-down’ to usb 2.0.

    Moreover, they also are a strong suspect in the problems with the stability of my dual external 24″ monitors.

    They are .advertised as usb 3.0 hubs — when, in fact, they have only 3 (of 7) 3.0 ports.
