Random Test. Reading or writing 4 KB blocks in a random location. Random IO play an important role in performance of your device. The slower random performance, the more possibility of lag. 3.

В разделе «Setting» по умолчанию стоит параметр «internal», в пункте «target drive». Это означает, что скорость чтения и записи проверяется на телефоне, то есть скорость внутреннего накопителя. Для проверки скорости чтения и записи внешнего устройства выберите параметр «Custom», затем в проводнике выбираем нужный носитель и «выбрать» Затем в меню «Benchmark» нажимаем старт В целом программа очень удобная и понятная

Cheap and utilitarian, the apps of this kind are the few ones here on appstore that actually serve a purpose. Kudos to its developers.

Due to low size file transfered, the speed are rather random for external drives, no way to increase the size.

Good app! Please integrate the name and the capacity of the entire drive/stick. Other apps do that but they have not the proper values.

Just checks your internal ipad or iphone storages and not SSD or whatever you connect to the device. If it was for the internal, we could just google it rather than buying an app which is useless after checking ones.

Проверено iPhone 7 128GB. С 1G Sequential тест получился Read: 538,95 и Write 291, 90 MB/s, что похоже на правду. Спасибо

Единственное, но качественное приложение в эпсторе такого типа. Простенькое, приятное по дизайну и хорошо делает свою работу. Так же приятна хорошая цена. В общем автор молодец и всего тебе самого хорошего;)
