Its one of the best apps to check ram speeds and copy speeds of sdcard and internal memory. I recommend that people should use this

I think the results are accurate. My device was Realme 6i. Storage read speed 430MBps RAM(lpddr4x) speed was 22GBps My class 10 Samsung sd card was having 74MBps read speed. Where they mention 95MBps read speed.
★★☆☆☆
Write speed always benchmarks at 0 for SD card.
★★☆☆☆
Didn't detect my card over USB. Most phones don't have SD card slots any more so not detecting USB devices makes the app sadly useless.
★★☆☆☆
Results inconsistent. Tested on Amazon HD 10 (2021) tablet. Internal storage Test Read 197MBs Write 32MBs Internal storage (same test couple days later) Read 66MBs Write 124MBs
★★☆☆☆
• SanDisk users BEWARE • While it did give me readings for 3 different cards on a ZTE Blade MAX, S8, and an S9+. It also ended up corrupting my cards shortly after taking the first few reboot tests. All were SanDisk 64gb Ultra Plus cards from Best Buy, so legitimacy wasn't an issue. I've also tested PNY Elite and Lexar Pro series 64gb cards without any issues. Just a word of advice, use this app at your own discretion and expect data corruption or SD failure at some point
★★☆☆☆
Corrupted my SD card after failing to continue random test following the reboot.
