Review on 💻 Enhanced Sony MRW-S1 High-Speed UHS-II USB 3.0 Memory Card Reader/Writer for Efficient SD Card Access by Olivia Herrier

I'm getting mixed results with this card reader. In one of the onboard slots on my motherboard (Asus Zenith ROG Extreme), it reads no faster than 30MB/s. In other slots, it reads 120MB/s from the same Sandisk 100x UHS-11 card. My Lexar XQD reader uses about 250 MB/s in each of these slots. This is copying raw files from a Nikon D500 to a half empty Samsung EVO 970. I've tried playing around with the drivers but this is the only device that doesn't work. don't behave as expected. In the right hole, it reads about as I expected. It's fairly cheap, but at one point it was billed as Sony's "fastest" reader, so that was a little disappointing.
