Top customer reviews
-Fits in the ExpressCard slot well, no loose wiggly feeling.
-Backwards compatible with ExpressCard Gen 1 slot, meaning it works in some older laptops at half speed (but still tons faster that USB2)
-It really does sit flush. I don't even notice the card in my laptop
-You won't get max USB 3.0 speeds, just not gonna happen, but it will be tons faster than USB2. My tests say about 50% max "theoretical speed"
-Does NOT provide ample power to higher power devices. It does have a little DC port for extra power and comes with a USB to DC power cable for a power boost, but it just doesn't cut it. I'm sure you can get an AC adapter that fits, but then you become tethered to a wall plug and no guarantee it will work.
I bought this for my older HP Pavilion DV7-3162NR laptop from 2009. The laptop is a 17.3" widescreen, upgraded to 240GB SSD, upgraded to 8GB RAM, with AMD 2.6Ghz Dual Core CPU, Radeon HD 4200 graphics adapter, an oversized extended life battery, and case mods to open up the CPU fan intake and exhaust. By no means is this a gaming or high-end laptop, but with upgraded specs and a big screen it's definitely still perfectly adequate for moderate usage. One thing that's missing, however, is any USB3 ports. That's where this StarTech USB3.0 ExpressCard comes into play. I have two USB 3.0 thumb drives and one USB 3.0 Monitor (ASUS MB168B+) that I'd love to run at full spec. The ExpressCard is finicky and sometimes has to be removed and reinserted for the USB sticks to read properly, but they do run ok at about 150MB/s, which is good enough. Now the USB Monitor works on the USB 2.0 slots, but NOT this USB 3.0 card. The monitor uses DisplayLink, which means it uses CPU and pumps the result over USB, so anything high-motion is too much for USB 2.0 and requires USB 3.0. This card simply cannot provide enough power to make the monitor even come on. I honestly attribute the speed and finicky-ness of the card to my laptop with aging components, but the monitor thing is most definitely a limitation of the card.
I have not tried any powered or portable hard drives, so I cannot attest to those working or not, but any device that requires HIGH POWER from USB will unfortunately not work with this card. The card is still a good device and a worthwhile purchase, but since part of the reason that I purchased this card was for that monitor, I am somewhat disappointed.
Now for the positives: This card works GREAT on my old Dell Latitude D830 laptop. I thought it was Windows 10 acting weird on dated hardware, (which it does) but it turns out you have to go into the BIOS and disable "PC Card and 1394" to allow the ExpressCard slot to function. Because I got a Code 12 error when looking in Device Manager. So if you have a laptop like mine, you probably will have to do the same thing if you need to conserve system resources. But other than that this thing has blazing speed! I copied a 1.4GB video file from my USB 3.0 flash drive to my computer at a peak rate of 100(ish) MegaBYTEs/second. That is amazing for a 2007 laptop to be able to write at such a speed. Didn't really need the USB-to-DC power cable for flash drives, but if you are going to plug in two portable USB 3.0 hard drives at the same time, you probably should use the cable.
Tight fit in the PCI slot.
Installation instructions were not accurate, at least for my system. I had to run a different exe than the one indicated in the instructions.
It works okay for fixed devices (non-flash drives) because they take advantage of write-through by default but even then I only get ~70MB/s throughput. Regular flash drives can only manage USB 2.0 levels of throughput. Even the flash drives that claim to be USB3.
