Review on 📱 Patriot 512GB EP Series A1 / V30 Support microSD Card SDXC: Ideal for Android Smartphones & Tablets with 4K App Optimization - PEF512GEP31MCX by Jay Swearengin

This review relates to the Patriot 256 GB A1/V30 Micro SD card. There are many fake chips out there, so we recommend anyone who buys them to download and run the test as soon as you get it. The first tests weren't very good - the read speed was 20 MB/s. I was upset as this would be the second chip I would have to return. (Already returned the Silicon Power Chip). I reformatted the drive and ran the test a few more times with better results, 78MB/s read speed. I also ran some H2testw-1.4 tests which were satisfactory. This drive had about 232GB of usable space, which is normal for many of the chips I've used. The chip is used with the Insta360 One R camera and has worked well for the first week of use.
