This review is from: StarTech.com 2-Port Flush Mount ExpressCard 54mm SuperSpeed USB 3.0 Card Adapter (ECUSB3S254F)It is beautiful and sturdy, it performs, it doesn't stick out. It works out of the box with Ubuntu (x64, 10.04). I needed to install a driver for Windows 7 (x64). The only downside is the price, which is a bit high....
This review is from: StarTech.com 2-Port Flush Mount ExpressCard 54mm SuperSpeed USB 3.0 Card Adapter (ECUSB3S254F)We users of slender laptops are jealous of the 2012 versions that have USB 3.0 support. So we mess with these skinny adapters to convert that nearly useless 54/34 ExpressCard slot into a functional USB 3.0 connection. I've personally tested several of these. So far this Star Tech #ECUSB35254F CARD looks like all the rest, BUT IT IS PACKAGED WELL IN A CARDBOARD CARTON, SO THAT IT DOES NOT GET DAMAGED BY ROUGH SHIPPER HANDLING; and, even more importantly, the BUILD QUALITY of the device itself seems better. The metal is stiffer and the ports stay in better alignment. The differences are very subtle. I did not use the included mini CD for drivers, but the device runs on the same Renasas 3.0 drivers as used by the other similar "AKE" models that seem to suffer a 50% defective rate. If you need two ports and have a 54 type slot, this is a good card to own. In general use you may not need the included extra-power cable; it connects to one of your USB 2.0 ports to add an additional half-amp max power to the Expresscard power, particularly if you use just one of the two ports. Also realize that the current spec of the Expresscard port can't handle the full 5.0 Gbps theoretical transfer rate of USB 3.0. You'll probably get on average about a third of that! Buy this model of the 54 size card. Save the headaches of testing and returning those cheap cards. Thanks to Amazon for making these great values possible. Fantastic shipping speed too!...
