Ratings and Reviews
Not Sure I Can Trust Accuracy
I’m trying to use Diskio to compare external storage access speeds on my 3rd Gen iPad Pro to my new iPhone 15 Pro. I’m also using Blackmagic Disk Speed Test on my Mac Mini to compare Diskio results.
Blackmagic is measuring about 680MB/s both read and write on an 800MB/s Sandisk SSD. Diskio is reporting 7808 MB/s write and 958MB/s read on my iPhone and 3553 MB/s write with 625MB/s read on the iPad Pro. Seems write speed is questionable AND the units probably should be Mb/s!
Ease of use is great. With the new USB C port on iPhones, more of you will be trying to measure speeds. This possibly could be the right tool if it were truly accurate.
Developer Response ,
Hello, thanks for your review!
In 2.0.0, we fully reimplemented the algorithm, so you can now trust the accuracy of the results.
Enjoy!
Needs Dark mode
Other than that, needs dark mode as my phone is on it but the app opens it in light.
Developer Response ,
Hello, thanks for your review!
In 2.0.0 we added light and dark modes support.
Enjoy!
Fantastic disk speed test app
Once you open the app you need to go to the bottom and swipe up to get to the settings.
Choose your location = SSD, disk etc.
Test size choice = 1,2,3,4,5 GB
Chunck size choice =1,2,4,8,,16 MB
Run test and the READ & WRITE scores will show.
*BONUS* You get a message with your score.
If your external drive is very fast, you have to read the sheer awesome message it displays in the end. Bravo Diskio programer(s)
