SD Card Test Pro

★★★★★ App is simple to use and if the graph is shown while testing would be visualized appeal

★★★★★ Really good app people and not very much money for pro version too and it's really easy to use aswell people love the app alot big time like people I was having hassles with my SD card moving apps over to it and ran the read then write tests and the app fixes problems too big time 5 stars and more honestly people

★★★★★ Be careful of the stop button (especially note10+ users). It's right at the bottom edge. If you want to test a large size like 500 gb, you might press on it by accident. Please developer. Put the start and top button in the middle of the screen. Otherwise, it's a very good app for verifying your new micros card.

★★☆☆☆ I bought this to test a 64 GB card to see if it was working correctly in a phone specked for 32 GB. Unfortunately, it fails at 4 GB because it refuses to write more than a single file in Verify mode, and VFAT doesn't support files greater than 4 GB. What, I can't reply to a reply? This is a stupid system, Google. Zoltán, I can't format it exfat because the phone doesn't support it. I know, I tried. The phone spec is for 32 GB but seems to work with a larger card; I was trying to verify that with your utility. It doesn't work for the purpose I bought the utility, so my low rating stays. "The utility works great, except anywhere you need to use it" doesn't help me. Format on PC: Did that before my last edit, phone just wants to reformat it. It's not really about the money, keep it. Make multi-files work in Verify and the utility will be universal.

★★☆☆☆ My Samsung Evo Plus 256 GB Micro SD Class 10 UHS-I U3 V30 A2 that I bought from samsung official store write speed drop from 51mbps to 14mbps after full write and read test
