1 out of 5 eggswon't support portable drives

Pros: some usb devices work

Cons: won't handle portable drives (that need power) - I tried two different drives
since it has an external power adapter, I assumed it was able to power external drives

the drives work on the usb ports of several laptops

4 out of 5 eggsNice Hub, But...

Pros: Small, USB 3.0 actually works on all ports

Cons: Wimpy power adapter detracts from a great product. I would have rated it a 5 otherwise.

Other Thoughts: This is a nice little hub that does indeed connect in USB 3.0 mode and supports USB 3.0 speeds on all ports. The more well known brand USB 3.0 hub I currently use that this hub is replacing only works in USB 3.0 on one or two of the four ports (it may be defective). However the StarTech engineers were obviously not thinking when they designed this one or else they got pressured into skimping on the power adapter to cut costs. The USB 3.0 standard specifies that each port is to supply 900 ma of supply current simultaneously as opposed to the USB 2.0 standard of 500 ma per port. But the power adapter provided with this hub is only a 2 amp adapter. Given the problems I had with my previous hub, the first thing I wanted to check when I took it out of the box was to see if it could support USB 3.0 on all ports simultaneously. So after connecting the hub and starting up the laptop it is to be used with, I connected four USB 3.0 portable hard drives in quick succession. All four showed they connect in USB 3.0 mode. As soon as I connected the third drive, the second drive unmounted with the usual "improper eject" warning. Then later it remounted on its own. This was the result of the power adapter not being able to provide sufficient current for all four drives going through their highest current activity (motor spin up from stop) all at one time. A quick speed test with all four connected seemed noticeably slower than USB 3.0 to me (68 GB was going to take 31 minutes to copy so I aborted it). With more typical use, this would be no problem except for devices which draw higher than typical current (motor activity: scanners with frequent motor reversals, disk drives during start, cameras with lens zooming, etc). Still the ports should be able to provide the full current specified by the USB 3.0 standard at all times. The hub itself does support full USB 3.0 speed with only one device connected and even seemed about 25% faster than the drive plugged directly into the laptop (9 GB test file copied in 1.5 to 2 minutes). What I am looking for right now is a substitute power adapter to use with this hub. The power adapter from my previous hub is indeed a 4 amp adapter that provides enough current to provide 900 ma per port so I may end up using the old power adapter with the StarTech hub, but it would have been so much easier if StarTech had provided a 4 amp adapter to begin with. Not quite plug and play. I think this hub is going to be worth it though. It is the best USB 3.0 hub I have seen so far.

5 out of 5 eggsGreat little hub

Pros: this is a nice little hub for a mobile system.

I had no issues with my W7 system. It just worked right away.

My Lenovo X1 carbon only has 2 USB ports and only 1 is USB-3.
The hub looks to be nicely made. It has an external (optional) wall wort supply, so you can charge devices through it and run multiple power hungry devices without worrying.
Plus the wall wort is a very light and small switching power supply.

All and all, a great mobile choice.

Cons: none so far.

5 out of 5 eggsWorks great

Pros: Power supply good for hooking up external drives

Cons: Cable worked for me, but probably could be a little longer

Other Thoughts: Works with Windows 7 right out of the box. Just plug it in and go.

1 out of 5 eggsTrouble with this product

Pros: None, whatsoever

Cons: Incompatible with Windows 7
Lost connected 2TB WD External HDD
Poor documentation, insomuch as no guidance on how to address issue.

Other Thoughts: Unfortunately, this product is the only thing I added to a brand new Windows 7 system and since then, I have had a HDD fail and inconsistent results getting anything to connect to this.

Too many hours spent trying to fix what should be a non issue.

Waiting for manufacturer response now.
