Atech Flash Technology Blackbird CX-2 Dual CFast 2.0 USB 3.0 Reader Writer for 4K Workflow. Supports Cfast & Cfast 2.0 cards. Ideal for Blackmagic URSA, ARRI ALEXA.

UPDATED REVIEW==============These readers are pretty amazing. Yes, the price is much higher than for a simple SD card reader. But there is that whole economy-of-scale matter (far fewer people need/buy these, which contributes to higher per unit costs).I've had my Blackbird CFAST 2.0 reader a bit over 3 years now, and it always works, and is insanely fast -- far faster than USB3.0. I'm adding the 5th star on for this long-term consistent top performance (I originally had given it only 4 stars due to price).ORIGINAL REVIEW==============I've used this only a couple-few times so far, but it has worked just fine each time. It's fast too. Note that the two slots share the same data channel, so speeds may be affected. But still, it's pretty fast. Connects to your mobo by one 20-pin USB3 cable. FWIW, my mobo has only USB3.0 (not 3.1) ports, and this card reader worked fine with that. The front fits cleanly into a 5" bay, so it looks nice in my PC's chassis. Happy with it so far. One star knocked off for being crazy expensive. But maybe that means it will last? (If so, why is this not being sold as of Aug 2018?)

Well, It's working really well. Nice speed. I'm having 610 mbps copying data from Card to My PC SSD.But problem is I don't have 20 pin slot on my motherboard. So I'm stuck with using USB 3.0 cable. And also coz of the same reason I can not fit this thing in my Cabinet. I have to keep it outside.

Work perfect, i use it with separate usb 3.0 cable type A and can used at the same time

transaction excellent, packaging good, installation seamless, worked great out of the box.

Reliable and fast!
