Fast SD/microSD card reader

I have several microSD cards that are supposed to be in the fast 100+ MB/sec read speed class, different brands from different sources, but none of them come close to that when I test them in any of my card readers, laptops, or phones. I'm guessing that the readers may be the bottleneck, just not designed to support faster cards. So I'd like to get a new USB 3.0 card reader that is fast enough to use these fast memory cards, but I'm not sure which one I could rely on. I'm looking on Amazon since I can add it to an upcoming order, but all the cheap card readers I see there are unknown brands and the reviews on all of them are split between "fantastic speed" and "doesn't deliver on speed", with no way to distinguish who's right. The only spec they quote is USB 3.0 max theoretical speed of 5 GB/sec, which is of course totally irrelevant.

So does anyone have a USB 3.0 card reader that they have personally tested to deliver card read and write speeds > 100 MB/sec? Any recommendations appreciated.

I use Transcend's RDF5, which I got from Maple Leaf Photo

When I test my memory cards with it, I get close to the memory cards advertised speeds.

I have the Kingston one mentioned above. It's very fast. But since it's out of stock and likely discontinued, you have to find a different one.

Just get one that is not a no-name brand and that says it reads UHS-II and you will be good.
