Wonderful app! Does just what it promises, and gives solid results with a minimalistic UI. You clearly invested time on the *internals* of the app vs. a flashy UI that really wouldn't add any value here. It would be helpful to allow selection of a couple devices from the database, and a "compare" button that would present a simple results matrix with a column for each device. As is, it's hard to compare w/o a lot of scrolling around. (I cut/pasted results numbers into Excel, which is painful!)

Ran perfectly, once. Tried a couple of other benchmarks, but they could not see cards and USB drives on my USB-C hub. This one sees everything, and can almost bench everything, except... It only ran perfectly the first time I used it. On that run, and that one only, it got through sequential write, sequential read, random write, and random read, and displayed everything it's supposed to. Every subsequent run gets through sequential write, sequential read, and random write, then crashes (like "poof! gone!") on random read. Restarted the app, uninstalled and reinstalled the app, no joy. But I can still get three numbers (sequential write, sequential read, and random write) if I watch the app and grab them before it crashes. That's more than any competing app has been able to do for me. The rest of the crowd gives just the two sequential numbers with no random read or write and no way to check the USB devices. --- Hi Maxim! It's a Samsung Galaxy S10+ Stock ROM Android 9 8 gigs of RAM --- And the write cache setting did it! I was able to figure out which USB-C hub was the best for my use, and how to use it. Thanks!

Thanks Joseph! I suspect in your case we have a situation when Android kills the app due to high memory usage while cache purging befor READ test. This might happen more often on custom ROMs or on devices with low RAM. KIlling other apps might help. OR enabling mem-cache in options
UPD: Glad it worked for you. Thanks for the review!
Not bad but maybe you should try adding a little description of each options? Like what the "write buffering" and "In memory cache" means and why you should turn it on or off. Also, the file size should be fully customizable since there's only a few options to choose from. If I remember correctly ½, 2, 4, 8 and 16 are all the options. This is just an app to test the read-write speed and there's a bunch of them on the store. So it's these little features that can make all the difference.

There's exaustive description in About section if the app ([?])
