We ran several tests to determine any potential performance penalties with the RHUB-310 when compared to the USB connection on the Gigabyte 780G. Due to the power requirements for our I-Pod and HP printer, the bus-powered setup is not capable of fully supporting the peripherals in these tests. The unit did work properly with four low power devices (mice, standard keyboard, thumb drives) connected.
In our Load Tests, we connect a variety of peripherals ranging from a Logitech G15 keyboard to a Sony A350 camera in order to populate all seven ports with a variety of devices commonly used to track any performance differences. Our bus-powered configuration will only handle four low power devices so we were unable to complete the full load data transfer tests.
Based on the results, using the Rosewill RHUB-310 Hub did not adversely affect performance in either the bus-powered or powered adapter mode in our single peripheral tests. In our full load tests, we noticed a slight slowdown of about 7% with six other devices connected. This is actually an excellent result considering the hub has to maintain communication between seven devices including game devices that use an interrupt protocol.
Quick Thoughts
With street prices around $24.99, very good ergonomics, excellent compatibility, and almost flawless performance, we cannot help but recommend the Rosewill RHUB-310 7-port USB 2.0 Hub. Of course, we base our recommendation on the user having the right mix of low or high power devices to match the capability of this hub. We put the unit through several days of harsh testing and used numerous peripherals without a problem. Our recommendation is to run the unit with the power adapter to ensure proper power support across most devices. We did not care for the mirrored faceplate design and the cable lengths could have been about six inches longer, but otherwise Rosewill has delivered a solid unit for the money.

google. are YOU lazy?possible query: "usb devices running slow (on) hub" or "why is [device x] slow (on) usb hub"

It was short and sweet and got to the point. It Let us know about a new product that some one might use. Not everyone has a new system. I have been a member since this site started and I come back to it all the time. It was because of this site that I was able to learn and build my first computer(way back when). This site use to have articles for every level. I for one think this site needs to have a few more articles for the newbies so that they can learn and become advanced.bakerzdosen - Tuesday, May 13, 2008 - link
Well, I personally would have liked two things:1) Test it with a bus powered scanner (like a Canon lide). That's the only problem I had when hooking up my mother's USB hub, was that her scanner wouldn't do full scans (previews were fine) via her D-link USB hub I just bought for her - even when powered.
2) A picture/description of the power brick. Smaller is definitely better here, and it seems that they're all out of control in size taking up 2-3 outlets if you use a UPS or surge protector.

Cool review, I just bought another hub with fewer ports and no power source for just as much money. My bad...impulse buy.Most important about the review is getting a little attention to the Rosewill brand. I have bought serveral of their products and have always been amazed at the value. These guys seem to launch one good product after another. I have several external disk enclosures that work, are well built of high quality materials, are beautiful as objects, and were releativly cheap compared to other lesser products. Even the least exspensive of their product range has always impressed me with high perceived value.
You don't see this brand marketed widely, if you do find something they make give them a chance I think you might be pleased.

I purchased one Rosewill external enclosure for personal use, it has been fine. I purchased another for the lab, and two Samsung hard drives have died in it. Suppose the drives could have issues, but seems a big coincidence.RamarC - Tuesday, May 13, 2008 - link
a usb hub? i could understand a wireless usb hub since they're somewhat leading edge, but a run-of-the-mill wired usb hub?there are already plenty of sites that do 'reviews' of mundane components. stick with hardware reviews for the enthusiast and the IT community.

My assumption is that Gary needed a USB hub at the lab, and that since companies send AT hardware all the time, he decided to do a three-page write-up on the hub he selected. I don't object to that, so long as the next great GPU or CPU review isn't delayed.Visual - Tuesday, May 13, 2008 - link
How about test with multiple ports used at once? Like two drives, a drive and something low-bandwidth, or even all 7 ports used at once?Also I'd like to see results not in seconds, but in kbps, just to show how close to the theoretical 480kbps the thing gets. Well yeah, I can recalculate it myself, but... you could too.
