Motorola Atrix4G GB 2.3.4 Works on Atrix4G (GB) non-rooted. My main complaint is that it takes up so much memory. Per Android OS information, SDCardTester takes up 25MB. Also, the app should make it apparent that you touch the right-most part of the directory to allow you to navigate to the SD-ext directory - rather I had to read it in one of the reviewer's comments to figure that out. Nonetheless, it works and gave me what I believe are accurate results.
Drois X2 user try again Works good, you have to double tap the path and it will bring up other paths. It's real touchy you have to do it in the right spot usually after the cursor. If they make changing location easier would give it 5 stars. It will switch paths on my Droid x2 just have to work at it.
SD Card Tester after buying a 128GB + 2 more 64GB sandisc micro SD cards from cex, and fully testing it with this superb app! All my cards are fake/false gig cards. 5 green stars! 9/10% also use this PC program called h2testw it works too. much thanks this ones a keeper.
Best tool to measure transfer speeds Very intuitive and reliable, unlike SD tools. Interface is basic. Maybe too simple. Would be much better if there were charts and graphs measuring speed over time and displaying max, min, and average r/w rates. Ability to save and report results would also be nice. One thing to note: This app can also test transfer speeds for internal memory and external USB drives. Just be sure to point to the correct path. Browse the /mnt directory to look for your drives. Common paths: /mnt/sdcard (internal), /mnt/sdcard2 (SD card slot), /mnt/usb0 (external USB drive-may need to select a partition)
Mixed results Worked on my Android 4.0 phone, where I had no SD card issues. Seems to write to free space so that it doesn't overwrite existing files. However, I installed it onto a KitKat phone (A 4.4.4) and when I started it I got the message 'Unfortunately, SDCardTester has stopped' (Report or OK) Unfortunately, it's this new phone that has the SDcard issues!
Superior to 'SD Tools' 'SD Card Tester' is an easy, effective method for testing both internal memory and external SD memory. This app is superior to the more popular 'SD Tools' because SD Card Tester is compatible with all cell phones. SD Tools will not work on Motorola phones, which I discovered the hard way. MANY COMPLIMENTS to the Developer for producing this excellent, reliable app. (Motorola Atrix HD with Jellybean v4.1.1)
