2 Port USB 3.0 to Express Card ExpressCard 34mm Adapter Hidden for Laptop

A bit of a tight fit, but nothing worrying. Works great.

I'm updating this again and for the last time. The ports are now loose and rarely make good contact. Even worse, I had been using it to move a lot of data back and forth on a portable hard drive and on the occasions it does work, it will likely break connection during a transfer. I am now forced to use the 2.0 ports on my computer that run much slower simply to be sure the data gets where it needs to go. Previous review update: This first paragraph is an update to my original review. I have two issues with the card. First, I occasionally have trouble reading my external drive unless I reboot my computer. Second, usb connectors don't seat as tightly as they should and I have to be careful to not move around or I'll lose the connection and have to reboot. However, it is still a good, economical solution for my usb 3 issues. My old Lenovo T430 laptop is an excellent performer that fills all of my needs. Of the scores of computers I have owned over the last 40 years, it is my favorite and I want to keep using it until it completely fails. I recently started having problems reading an external hard drive through the computer's two USB 3.0 ports; however, it works fine (but slowly) on the USB 2.0 ports. One thing I noticed is that a microphone and thumb drives work on the 3.0's. I can also hear the hard drive run when plugged in, but it's pilot light is dimmer than when plugged into the USB 2.0. This leads me to believe that there is a power problem with the faster ports that is beyond my ability to troubleshoot and repair. I'm also not willing to potentially spend several hundred dollars to have it repaired. Fortunately, the computer has a 34mm ExpressCard slot which led me to a search for a USB 3.0 adapter that will fit it. A quick search lead me to this and other USB 3.0 adapter cards. The highest rated one contains a single port, which is a problem since I occasionally need to plug in two external drives so that I can transfer very large files. Since I do not want to use the substantially slower 2.0 port, I took a chance on this adapter with its two ports. It arrived on the promised date, packed with a miniature cdrom containing a needed driver. Here is my only complaint with the adapter card. When inserting it in the slot, it required enough effort to make me concerned that it was not fitting in correctly. Before committing myself, I double checked that it was properly positioned, then pushed it all of the way in. This is a typical card slot that should allow a card to be removed by pushing it so that it clicks and partially ejects. However, this fits too tightly to allow that action. I feel lucky that the card works properly since I will definitely have a problem if I ever need to remove it. That problem aside, I tried to read a drive without installing the driver and as expected, it didn't work. With driver installed, the computer recognized the hard drive and I was able to fully access it. I also read and wrote a large file through the card and it appears to give speeds typical of 3.0. There is one other issue that wasn't a problem for me, but may be for others. The driver was supplied on the cdrom and I did not see any reference for how to download it if the computer does not have a cd or dvd drive. So, barring a future problem removing it, I am very pleased to say the adapter card resolved my USB 3.0 problem for only $24!

It didn't "disappear" in my laptop! I have to remove it every time I pack it into its case or it won't fit easily or it would get smashed. Otherwise it's definitely faster than the UBS 2, it slides right into place so installation is easy, but it's not so easy to get back out. It's a good value for the price and if you don't have USB3 it's nice to have 2 USB 3 ports. It comes with a driver disc, but my laptop recognized it right away and loaded the drivers automagically.

I'll make this succinct. It's definitely a good product and works well. See below 1. For windows 7 and lower the drivers (included on a disc in the package) need to be installed. Also plug the device in first then install the drivers 2nd. 2. The Expresscard will get warm if anything is plugged into it for a long time (into the USBs) so just keep an eye out for the and don't keep things plugged in for a long time. Product works well

This did work, eventually. It was flimsy as hell and didn't want to fit into my laptop's ExpressCard slot in either orientation, nor does it work with the slot's push-to-eject function. After much fiddling and a few choice words, I eventually did get it installed, but it's jammed into the ExpressCard slot too tightly to be removed, making it a permanent addition to my laptop.

works as intended

Poorly made. Would not work.

My Lenovo W530 still works great, it just needed more USB ports. This solved the problem right away.

Plug and play under Linux Mint. 10x the transmission speed of the laptop USB ports.

It arrived this morning so after unpacking it (huge amount of packing for such a tiny item) I pulled out my Panasonic Toughbook CF-19 and plugged it in. After booting into Linux Mint 32 bit, I connected an external SSD drive and it just worked - copy tests showed good speeds so I am very happy with the 2 Port USB 3.0 to Express Card ExpressCard 34mnm
