2 out of 5 eggsWorks occasionally for USB 2, or slow device charger.

Pros: Good idea, I bought this originally for my Lenovo T510 to add USB 3 since I have several USB 3 flash drives. When it works the speed is excellent and fairly close to the built-in ports on my desktop (100mbps seq read). Sits flush with side of laptop. Has port to supply extra power.

Cons: When inserting a usb connector it pushes the card in and then makes it want to pop out. When removing a flash drive it will rip the card out of the expresscard slot. 90% I can't even get a flash drive to be detected by this card even though the card is displaying in device manager with no problems and latest firmware and driver. I think this is a physical issue though.

The port is really tight and the outside is basically just like the edges of some sheet metal. It is nearly impossible to get most of my devices to plug in, though my phone cable slides in easier.

Also, though this is not terribly accurate, I tried using included cable to provide more power. My phone did not show that it was getting anymore power when I had the USB A connector of the auxiliary power cable plugged into my computers USB port. It showed about 100mA. Then I tried plugging it into a USB phone charger-no change.

Other Thoughts: I basically have never used this card since I had never really been able to get it to work. I purchased it so it would be flush with the side of my laptop and I could leave it in. Now I wish I would have bought a 2 port card. Despite adding the extra bulk, I think it would actually work due to having the extra plastic to keep the card from popping out when inserting a device and it would allow you to hold onto something when removing. Oh, I have also tried using it in my T430 to add a third USB 3 port with the same results. Get the two port and plug it in when you need it--at least it will work.

5 out of 5 eggsBest Thing i ever Bought for an Older Laptop

Pros: Great Transfer Speeds
Instals on Windows 7 without Driver (for me At least)

Cons: Does not sit 100% flush in the laptop, not Star Tech's Fault, it probably HP's, it sticks out maybe 1/8th of an Inch.
Every Time you pull out a USB Drive from it, it Slides out with it, then you got to push it back into the spring (Still 5 Eggs)

Other Thoughts: Works with an HP Elitebook 2540p for those who want to know

5 out of 5 eggsLove the card

Pros: I just ordered the card for my 2 laptops. I filled my 2T drive with 1T of data using the slow USB2(25/mbs). This card took it up to 125/mbs. I did not need the extra power cord. So it gave me an extra USB port.

Cons: none

Other Thoughts: I have a Dell M6400 and a Lenovo Thinkpad W520.

5 out of 5 eggsWorks fine with Linux Mint

Pros: Windows 7 found the card, and a quick test showed that a file transfer from an external hard drive took less than half the time as with USB 2.0 Then in a quick test with Linux Mint 17.1, the same file transfer took less than a third of the time as with USB 2.0. Tried a couple other Linux distros, but they didn't find the card. Go Mint!
Card does what it promises, a nice inexpensive upgrade to a laptop that lacks USB 3.0.

Cons: None.

3 out of 5 eggsDoes the job with inconveniences

Pros: USB 3.0 speed port that supports high power draw devices.
Easy setup.

Cons: 1) USB port is way too thin and tight.
2) Pops out of the slot because of 1)
3) Requires an external power source to run.
4) No USB Super Speed.

Other Thoughts: I bought this to make use of the USB 3.0 speed for my new External HDD,

The drivers installed fine. I didn't get recognition of my External HDD at first, then I plugged in the external power USB, and then it functioned at a maximum transfer speed of 60MB/s or 400mbps for 1.4TB of data transfer. Thus, if you're looking for SuperSpeed, you're not going to get it. My guess is because ExpressCard itse'f won't go beyond 66MB/s on its bus transfer, so you're going to be restricted to this level of data transfer as well.

The main gripe is actually the USB port itself is narrow enough to grip and clamp on to your cable. Good thing for a robusts connection where you aren't fiddling with it to see if the pins are contacting. Bad thing is that you'll yank the ExpressCard itself when you want to pull the cable out.

The other is that it will only function with an external USB power source. Unless you got lower power devices like USB sticks (Haven't tested these), you're always going to need another USB port dedicated to the port. So essentially you are not expanding your number ports, but converting 1 to USB 3.0. Liveable, but not optimal for an "expansion card." If you are using an external USB charger (mobile phone chargers), then you'll have +1 port, while requiring 2 AC plugs, and an extension USB cable. I'd better suggest using the 2 port USB 3.0 by Startech that sticks out of the ExpressCard if you want to expand even +1 (+2 if you use 2 AC plugs).

Overall, it does the job, but I'll still be looking for a good USB 3.0 ExpressCard.

Manufacturer Response:

Hello John,

Thank you for taking the time to leave a review for our ECUSB3S11, and we are sorry to hear it did not quite meet your expectations. We would like to offer some assistance.

Regarding the port tightness concern, this is not something that we have typically seen with this card. It’s possible that the USB chassis is faulty. We would be more than happy to send you a replacement card that should not have this defect.

You are correct regarding the amount of power that is supplied via ExpressCard. This port does not supply much bus power, meaning auxiliary power provided via the USB port, using the cable we provide, is required for higher powered devices. This is almost always the case for external hard drives. Devices such as USB flash drives should be fine without it, as you have noted.

It’s also conceivable that your computer has an older generation of ExpressCard (Gen 1.0). Gen 1.0 ExpressCard enabled computers support a maximum throughput of 2.5 Gbps, while Gen 2.0 ExpressCards support up to 5 Gbps. The ECUSB3S11 should support speeds of up to 5gbps, but will only perform as fast as the slowest variable.

If you would like to have your card replaced due to the USB port, or if you have any further questions, please do not hesitate to contact us. Make sure to reference case # 303-187718 when doing so.

5 out of 5 eggsworks like a charm

Pros: usb 3.0. I get speeds upwards of 80mb/s second. works without driver update. plug and play.

Cons: none

Other Thoughts: the individual complaining of not enough power must understand the power output of an express card is lower as the card itself uses more power and has less to spare for the usb port. for those of you concerned about that the card comes with a USB cable that can plug into another USB port and can then be connected through the little circle plug on the card. this increases the power output for larger USB 3.0 devices.

3 out of 5 eggsok

Pros: Adds a USB 3 port to my computer.

Cons: Doesn't have enough power to run a slim USB optical drive to read a disk, certainly won't have enough to burn a disk. Being used in a Dell Latitude E4200 with CentOS 7 and 5gb of RAM.
