Question about SanDisk Professional PRO-READER CFexpress

The multislot readers are usually very old and have slow USB 2.0 or even 1.1 connections. Let's be honest. What else do you need? SDXC maybe, and I'm sure you already have that. By the way, you can also insert SDXC cards into the same slot in the Sony Reader for CF Express A cards. It doesn't need a second slot for that.
