5 out of 5 eggsWorks well with updated drivers/fw

Pros: Full USB3 speeds. Short profile means it is flush with the end of my expresscard slot

Cons: Did not automatically pick up the correct drivers.

Other Thoughts: I bought this for a Lenovo X220 running Windows 8.1. I plugged in the card and installed drivers, but my laptop acted quite funny. The mouse wouldn't track smoothly and video on the screen was choppy. Also, USB drives I plugged in wouldn't be detected. Things would work properly after a reboot, but after letting the laptop go to standby, the issues returned. I checked in Device Manager and saw that Windows was using the built-in Microsoft drivers instead of the Renesas ones I installed. Right-clicking and saying "update drivers automatically" told me the best drivers were already installed. So I went back in and manually selected the Renesas drivers. Lo and behold, everything works much better now :).

Also, if you go to StarTech's website, there is an updated driver to use. Inside the folder, there is also a firmware update. I applied it.

4 out of 5 eggsWorks well enough to get another one!

Pros: - Works as described

- Comes with the power adapter cable for external drives without their own power source.

- Data transfer is reliable and fast for my uses

- I can hot-plug / hot-eject while the computer is on (as long as I pay attention and make sure all processes using the drive have been terminated)

Cons: - when plugging in an external drive without power, sometimes I get the "this drive is faster if you plug it into a high speed port" even though the external power adapter is plugged into the wall

Other Thoughts: One more for the "Cons", but this is not a fault of the manufacturer, just a fault of the ExpressCard design in general:

It's nice to be able to use a little pressure when plugging devices in to make sure the plug is fully/properly seated, but if you do that on this device, it may eject the card so you always have to be careful when plugging in, especially while the computer is on.

4 out of 5 eggsDoes the job

Pros: Works as advertised in my 4 year old Lenovo T400. Gives full USB 3.0 speeds to the USB 3.0 thunb drives I've attached to it.

Cons: USB 3.0 sockets a little tight getting in, a tendency to pull the card out of the laptop when pulling the USB drive off the card.

1 out of 5 eggsHave to reboot thelaptop to get drives to mount

Pros: Nice, flush design.

Cons: It won't recognize connected USB3 hard drives unless I reboot the laptop. I updated the firmware and the driver to the latest available from StarTech website. I tried older drivers too to no avail. I disabled USB3 power management, same results. So it's pretty useless to me. I don't want to reboot the laptop every time I connect a USB3 drive. I'll be returning it. I give it 2 stars for neat, flush design, but unfortunately it doesn't mean a lot since the card doesn't work well. This seems to be a common issue with Renesas USB3 controller judging by the number of forum posts on Dell, Lenovo, HP, etc. websites.

5 out of 5 eggsWorks as advertised, fixes major oversight by dell

Pros: Gives me USB 3.0 speeds for accessing a 2 TB 2.5" external. The PCI-E lane on my Dell XPS 1645 powers the HDD too. Observed sustained 60MBps data transfer to and from the HDD, which should be around the max for this little drive. Fits flush with the slot and fills the whole slot, so it looks good, too.

Cons: None to speak of, may need external power for some 2.5" drives in some systems, or 2 2.5" drives

Other Thoughts: Managed to fix a major oversight by Dell (USB 3.0 was new in 2009, but hey, it was a top of the line laptop).

1 out of 5 eggsGarbage

Pros: None

Cons: This thing is a piece of garbage, the tech support is useless and just wants you to install driver after driver until hopefully something magic happens and they work. I still can't use it as it doesn't want recognize the controller. It worked once... but after that I couldn't read or write to the drive it just saved the index... great

3 out of 5 eggsConfirmed Power Issue

Pros: Definitely delivers on the USB 3.0 speeds and compatibility. I was able to get this working with both a LaCie Rugged 500GB and a HGST Touro Pro 1TB in both Windows 7 and Windows 8. However, the reviews are correct about the drivers being a pain in the a**.

Cons: The drivers are there, and that's nice but getting them to work was more trial and error than plug and play.

BIG Con is the power draw. I'm not sure what 2 USB 3.0 devices you could run at the same time, but I know that I tried both the LaCie and HGST mentioned above plugged at the same time and -- like other reviews have stated -- both drives drop out. And no, adding the power adapter (at least the USB to DC adapter supplied in the box) does NOTHING to avoid this issue.

The moral of the story -- don't try to run 2 drives at a time on this thing. It won't work.

Other Thoughts: You get what you pay for. I wish I knew where the gold standard is for an ExpressCard USB 3.0 adapter is, because I'd pay whatever I needed to so that I could have it. I suppose with these ports coming standard on most laptops today it's a moot point, but I still have a few years left on my XPS Studio 17 and Latitude E6500 series laptops.

1 out of 5 eggsWorked sometimes, then died

Pros: Installs flush which is great for my application. It was very fast when it worked.

Cons: Driver support/instructions were terrible. I had to read reviews on here and other sites to figure out which files on the CD to use. Then I updated to newer drivers and firmware also described in online reviews. It would work fine for a while, then disappear requiring either a reboot or ejecting and pushing the card back in. It finally quit working all together, and isn't recognized by several different computers. Outside of 30 days so I'm out $40. I just ordered 2 different cards from another site for $10 shipped each. Hopefully one will work.

Other Thoughts: If this worked all the time as it did sometimes, I could have overlooked the short comings with the drivers/instructions. Even if it still worked, it only intermittently worked for me in Win 7 anyways. Now that it's dead, it's good only for keeping dust out of the slot.

4 out of 5 eggsSEEMS FINE NOW

Pros: FLUSH MOUNTING and also comes with power cable to boost power from another usp port if your machine lacks enough power from its native port. pleased to have 3.0 on this notebook.

Cons: DRIVER HASSLE... supplied cd is worthless. 2nd download from site and it installed normally. MAY unplug if not held in when removing flash drive... not a big deal.

did get a copy failure when it said the filename was too long. never had that problem on 2.0. it just truncated instead of continuing to copy and leaving message about file not transfered. maybe its an xp problem.

Other Thoughts: Tech support responded to email in reasonable time, with a detailed note. overall pleased at this writing.
