wierd interface
The graphical interface is some wierd custom job, so it has a huge transparent border surrounding it that isn’t so transparent in the latest OS X. It’s distracting, and wreaks of a non-native app. For such a huge interface, it doesn’t tell you a lot of useful information. You don’t even know when the test will end, or how far it has progressed.
To top it off, the interface is super wonky, and you have to sort of figure it out. That being said, it appears to work, and is an accurate measurement of drive speed. But if you can’t trust the interface, and the wonkiness, can you be sure the app itself isn’t leaving junk data all over the place as part of its testing? NO evidence of this, but it makes you worry. No app should make you worry.
