Review on πΈ SanDisk Extreme 64GB microSD - SDSQXA2-064G-GN6MA: Enhance 4K UHD Performance with A1/A2 Capabilities by Nelson Calafell
Faulty or worse.
Product label differs from box label. The microSD card is labeled "Extreme" and the blister pack is labeled "Extreme PRO". I've tested on multiple readers, including the included full-size SD card adapter. I compared this to an old 32GB SanDisk Ultra MicroSD that I used. Ultra meets specifications. This Extreme recorded a repeatable write speed of 8.9-9.4 MB/s. The read speed was stable at 16.3-16.6 MB/s. It uses Satechi and Cable Matters USB-C USB Type 3 and 3.1 readers. The default is 90/100 MB/s, write/read. Also, my 2016 MacBook Pro took up to 20 seconds to mount the volume, while every other card I tried mounted almost immediately. Something is obviously wrong with this card. I have requested a refund. This is the only SanDisk SD or MicroSD card (out of 15 cards I have, ranging from 2GB to 128GB).
