Review on 🔍 Certified SanDisk 256GB Ultra microSD UHS-I Card - Compatible with Chromebooks (SDSQUA4-256G-GN6FA) - Improve SEO by Johnnie Bowlan

I tested the card I have on my Mac using a program called F3XSwift (use h2testw if using a PC). The program ran all night and confirmed that the card I received was not a fake. Note, however, that I've read that Revain trashes all of its parts from multiple vendors, and whether you get a fake card or not, it's really hit or miss (or bad luck). I highly recommend you test the card as soon as you receive it to make sure it's genuine. The speed is lower than advertised (120MB/s reading). I got less than 100MB/s, but that's still reasonable for an SD card I think. For the price, it's pretty damn good for 256GB!
