Review on 💾 USB C Thunderbolt 3.0 SD Card Reader: 1TB Capacity, OTG Adapter for MacBook Pro/Air M1, iPad Pro 2021, Android Galaxy S20/S21 - White by Tim Paolucci

This seller is advertising a reader with speeds of up to 5Gbps which is completely false. I'm using a v90 SD card (280MB/s read) with an SD card reader connected to a USB 3.2 Gen 1 Type-C port (5Gb/s read) and cut/paste it into it Samsung 980 Pro Gen 4 PCIe 1TB a . NVME SSD with 11th gen Intel 11900k processor (5100MB/s write) and I'm getting a speed of 80-85MB/s. As shown in the screenshot, I have the card set to Best Performance. So if I'm not missing anything, the seller is lying about this item. I think if this seems too good to be true, it really is.
