(Note that this review was originally posted in 2005, so it's been a LIFETIME for an electronic device and the DUB-H7's you buy today are likely quite dissimilar insofar as their physical construction goes compared to the ones from 2005.)
I've had one for about six months now, and it's worked without problems. One of the things I particularly like with it is that it comes with one of the newer "slimline" power supplies that doesn't block other plugs, works anywhere in the world (100-240V), and is more efficient than the old "wall wart" power supplies.
Let me address some of the other comments here:
1) For the guy with the Lexar data card... it is a blight on D-Link's reputation that their technical support was clearly incompetent (this is sadly true of many companies today -- being pushed there in part by the relentless "drive to the bottom" by consumers who often care more about price than quality and support), but I doubt that even a really good company could have helped much. Although the hub may have somehow been at fault, it's also possible the Lexar card had problems -- even if it worked fine in other hubs. For the record, I've used a handful of USB drives with this hub without problems... although not a Lexar brand.
2) Regaridng plugging in a USB 1.0/1.Read more ›
Finally, if you buy the hub, I suggest going to Windows Update and downloading the optional USB 2.0 fix for WinXP SP 1.
It's a smallish hub, but not one so tiny that the ports are so crammed together so as to be nearly useless. At 4 inches wide and less than an inch tall, the hub should easily fit on any desk, and the rubber feet help hold it in place. The ports are widely enough spaced that you shouldn't have a problem attaching cords, thumb drives, or other USB devices.
Since I planned to use it only at my desk anyway, the caveat that an A/C adapter is required didn't bother me--but I've found that the hub works fine without any A/C power at all, and despite the instructions claiming it doesn't draw power from the USB bus, the power LED lights up, and all devices work fine. Without the A/C adapter in use, the hub also runs quite cool and doesn't suffer from the lock-up problems others have mentioned.
If you plan on using mostly powered USB devices--like printers, external hard drives or CD/DVD drives--you should be fine using the hub "unpowered." Using it for a keyboard, mouse, barcode reader, and thumb drive may require the use of the A/C power for reliable operation. And if you're worried about putting too much of a power strain on your laptop's USB bus, connect it via a docking station (as I do) or use the A/C adapter. Still, with that said, many people should be able to use it just fine without having to add another bulky "leech" to their power strips.Read more ›
Using a RAID0 (Striped) source drive (10,000 RPM WD Raptors) with a consistent throughput of 160MB/Second I copied 5.0 GB to the following drives:
- Standard 5400 RPM SATA (SATA 3GB/Second interface) - Transfer Speed 55MB/Second
- Standard 7200 RPM SATA (SATA 3GB/Second interface) - Transfer Speed 77MB/Second
- USB 2.0 5400 RPM external drives - Transfer speed 34MB/Second
- USB 3.0 5400 RPM external drives - Transfer speed 72MB/Second
Using a USB 3.0 External Hard Drive 5400 RPM as the source copying to another identical drive on the same USB 3.0 HUB I copied 5 GB of data with a transfer speed of 80MB/Second. It makes no difference whether the drives are on separate controllers, plugged into a USB 3.0 port by itself, or whether the drives are both plugged into the hub. If you are like me and move tons of data around you will find USB 3.0 MUCH faster the earlier technologies including even the latest Firewire iterations.
USB 3.0 speed of 4.8Gb/Second is a huge boost. At ten (10) times the speed of USB 2.0, the external hard drive bottleneck has moved from the connection speed to the speed limits of the hard drive itself.
- Fast, even with 4 drives attached.Read more ›

I bought this USB hub to use with my Raspberry Pi 2. First of all, I love the size and design of this hub. Read morePublished 1 month ago by Nathan Kiewel
Caution, if you are using this with hard drives, it is not the most reliable. It loses power and ejects the hard rives unsafely. Would recommend researching a more reliable hub,Published 1 month ago by keith.1
