Blackmagic Disk Speed Test App Reviews

When will test for 4K. on MacBook pro?

Says compatible with 10.6.6 or later. Tried running on my 10.6.8 and na-da.... So much for that.

Updated previous version which worked. This one doesnt.

As soon as i click the icon, it crashes! Cant even see any graphic or window, it just doesnt work. I have a 64bit processor and osx 10.6.8 as required...

I’m on MacOS 10.12; This program doesn’t even start.

Works on 10.10. If you are having problems, make sure you have chosen a writeable directory on your target drive.

This version freezes on start and is causing other problems after being launced with other apps too forcing a restart.

I’m on macOS Sierra. It’s working perfectly and I can’t believe this app is free !

Crashes on opening every time. I would have given it zero stars but you cant so i gave it a one.

最新バージョン3.0はOSの互換性について10.6.6以降と書いてありますが、10.7.5 Lionでは使用できませんでした。また、他の方もレビューしていますが、10.6.6 SnowLeopardでも使用できないみたいです。この点について海外のApp Storeサイトでも、「デベロッパーによるOS互換性の検証がされていない（Such as , not even test their own app after their updated it .）」ようで、少々残念。 BMDにはDaVinci Resolve のような優秀なアプリもありますから、デベロッパーのアプリリリースに於ける姿勢が他のソフトウェアの信頼性に影響を及ぼす可能性があるのではないかと疑念が芽生えてしまいます。

It is not working on Mac OS X Maveric, crashing just after start.

Crashes after trying to select the drive.

poor gui design, nobody knows what is measured at the moment. I will go to find something more usefull

Works perfectly on MBP z El Capitan. In my opinion it should only stop automaticaly after performing any test. Otherwise it can run and run endlessly if you start and go away from the computer for a coffee break or so...

Thank you! Helped to find out that one of my HDDs is too slow, need to replace

Need SSD to smile =))))

When try select another drive, application crash!

You were wondering how can read/write speeds differ based on whether you are using PAL or NTSC in your digital files? Well, install this joke of an app and it will tell you that your disk performs better in NTSC! The whole idea of basing all the results around video formats is crazy: disk performance has nothing to do with formats, but with file sizes, disk fragmentation, etc. Also this app does not take into account the possible presence of “fusion” drives, with ssd caches boosting the conventional drive performance. There is no setting to test for random/continous file access, no setting for smaller file sizes. Conclusion: it is a toy, a joke, and not a serious benchmark.
