SD Tools

Completely wrong results. Also, the info displayed is mostly from external card, but doesn't differentiate from internal card.

Got 2885 read speed and a 9626 write speed. I hold the record now :) used a Kingston class 10 16gb micro SD card as well....

Set the correct path to my SD card's name and it would show "Error writing buffer". No idea what's going on, would love to know why is it happening.

Error writing to ext sd card.. known kit Kat issue. But would be nice if someone could solve Google Crapo

There is some problem that the app is not letting me send the test data!!! By the way the test hase been done and i also can save it.

crashed! Uninstalled until developer responds to my email. gauges are very small on my screen. device tested ok. ext card test made app crash. error writing. last app update dec 2013.

This is due to problems with permissions. It should be fixed with 6.0, however, there are still ways for apps to access the SD card, but the dev doesn't appear to implement a fix on this. The app doesn't appear to know how to create its own directory

this does not check the ext card, i used it on a 16 Gb card it only detected 4 Gb, my internal available memory. take fake apps like these out of the google store

First, it was difficult to select my SD card rather than internal storage. Second, it had an error and could not perform a test. Third, before I could close down the app the whole thing crashed. It also doesn't seem to attempt to verify size, which is what I'm looking for in an SD card tool.

Does exactly nothing apart from a speed test. Don't bother with it not worth the time it took to read this comment

I can't check my sd cars coz error writing buffer pls fix it. Thanks

The speed test shows sd card speeds 3 to 5 times faster than what the manufacturer advertises, come on

Massively inaccurate on my Zenfone 2 ze551ml . Reported read speed of 780 MB/s, which is about 10-20X what is physically possible. Reported write speed of 74.1 MB/s, which is probably 2-4x what is physically possible.

Results are totally fake geting read speed of 114mbs then 54mbs write speed of 90mbs I have class4 man this app is waste

i found no other app like this. probably best on android. pls add an option to test the speed of internal storage also.

Have a note 10.1 2014 and tested with this app a micro sd 64 gb coz it unmounts all the time it shows nothing is wrong unfortunately it unmounts I put in 32 gb and never unmounted so I know it's the sd cards fault it's a sandisc I've tried other apps 1 has responded giving them full stars for responding even when they couldn't solve it if u do solve it ide pay full version so I know every sd card I put in I won't have troubles so then if u want stars I'll give u 1 month to respond thank you

gives me write speed of my SD card will do read testing on my ROM. So apparently it's made by 3 - 4 years old standard + 4 32 gig SD card the fastest in the world with read speed off 230 Mbps....... you wouldn't expect anything more false or misleading. This is after I corrected the path and pointed to my memory card.

Confusing. Shows info on phone's emulated SD but I could not figure out how to change to real SD. GUI partially corrupted. Will remove very soon

On Samsung Core Prime and 32 GB card, it shows around 300 MB/s write and 750 MB/s read which cannot be correct, cannot send results either

Results are totally fake geting read speed of 114mbs then 54mbs write speed of 90mbs I have class4 man this app is waste

1. Not user friendly(GUI can be improved) 2. Not able to run (Immediate write buffer error) 3. Crash when closing. Not recommended.

Used this to benchmark my OnePlus One, and I got over 170MB/s read and 112MB/s write.

Xperia Z2 Lollipop.

“Error Writing Buffer" is the message at each failed attempt to speed test my brand new (and tested/proven working) 64gb Samsung EVO card in my bone-stock Sony Xperia Z3 running OTA Android 4.4.4! Please fix it and I will adjust my rating of this app accordingly.

Said my phone write at 200mb and reads at 600mb. I don't think so.

Can't work on htc one m8 with sandisk micro sd extreme plus 32gb

Doesn't work on my S5 or Note pro 12.2

App not working fails to write data

I the ads make it ugly but the devs need some revenue !

Great app. Gives you the hidden speed you need to play those larger games. Nice job!

Using note 3 with stock firmware, unrooted. Tried /mnt/extSdCard, failed to write, crashed. Tried /storage/extSdCard, failed to write, crashed. The ads display fine though, that earns you one star!

On GS5 it won't allow checking of external SD card which is what we want to test. Anyone can test and benchmark internal memory which is all this app does.

Does not let you select external sd

Doesn't work on my S5 or Note pro 12.2

My sd card is broken and needs to be formatted and the speed is 100mb this is bullshit
