There are several benchmark tools on Google Play Store to benchmark SD card performance. After tried out some of them, I found out that SD Tools and A1 SD Bench provide accurate and consistent data. SD Tools is good but it can’t be used on certain Android devices like Samsung Galaxy S3 and Galaxy Note 2. But it is working fine on Galaxy S4. A1 SD Bench works on every of my Android devices. Besides, it provides the ability to test internal memory, SD card and system RAM too. However, it includes cached data sometime. Therefore, you need to benchmark several times to get the correct result.

A1 SD Bench is one of my favourite SD card benchmark tools for Android. And it is updated to version 2.0 which 4 benchmark modes support – Quick, Longer, Accurate and Random I/O. It is a free and without advertisement application that can run on all my devices. Besides, it can used to benchmark RAM and memory (USB flash drives and USB HDD too). You can also see others’ results online.
