Add a USB 3.0 port connection that inserts flush into a laptop ExpressCard slot. The ECUSB3S11 Flush Mount 1-Port USB 3.0 ExpressCard lets you add a single USB 3.0 port connection to your laptop through an ExpressCard slot.

The USB 3.0 adapter uses a unique form factor design that allows it to sit fully in a standard 34mm ExpressCard slot without sticking out. The port sits virtually flush with the sides of the laptop, enabling you to leave the card installed even while on the move, without fear of damage to the card or slot.

Enhanced with UASP support (USB Attached SCSI Protocol), this USB 3.0 controller performs up to 70% faster than conventional USB 3.0 when paired with a UASP supported enclosure (Note: UASP requires a compatible operating system). Using a more efficient protocol than the traditional USB BOT (Bulk-Only Transport), UASP technology optimizes transfers by allowing multiple commands to be processed simultaneously, significantly increasing transfer speeds for less wait time on data transfers. See our UASP test results below for further details.

The USB 3.0 ExpressCard adapter supports data transfer rates up to 5Gbps, and is still backward compatible with USB 2.0 at up to 480Mbps, or USB 1.1/1.0 at up to 12/1.5 Mbps respectively.

Backed by a 2-year warranty and free lifetime technical support.

Improved Performance with UASP

UASP is supported in Windows® 8, Server 2012 and Linux kernel 2.6.3 or later. In testing UASP performed with up to a 70% faster read / 40% faster write speed over traditional USB 3.0 at peak performance.

At the same peak in testing, UASP also showed up to an 80% reduction in required processor resources.

Test results were obtained using an Intel® Ivy Bridge system, add-on USB 3.0 cards, a UASP-enabled enclosure, and a SATA III solid state drive.

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.
