Blackmagic Disk Speed Test App Reviews

Fake

This is just a program that tells you false information about your MacBook because it is trying to make you think "Oh wow my macbook is so slow. I better buy the new one!" The numbers are bull and I know my MacBook is faster than what it says it is. IT IS A SCAM!

Handy dandy

I saw the app in action at screencastsonline. The timing is good on my part as I am waiting for delivery of a Drobo. Contiplating which bus to hang it on. This is the perfect tool for making the decision. I just want a simple answer and the app delivers!

Does what it says, but...

Since SSDs have a limited amount of writes in its lifetime, is it really the best idea to run continuous 5GB at a time write tests? Especially when it doesnt tell you when the test is over. I have a 13" Macbook Pro and the application window doesnt even fit vertically on the screen. Not a big deal, but not impressive either. I dont buy into the whole video benchmarking aspect of this app. Seriously, if your SSD isnt fast enough to buffer video frames to memory during playback, nothing will really help now, will it? I would hate to use a video player app that streams directly/inefficiently from storage anyways. I can see if a video is a couple of hours long and uncompressed, surely its not smart to load the entire thing in memory, but a good video subsystem should buffer enough frames so that storage doesnt have to struggle or that the engine doesnt have to drop so many frames to keep up - or one would sure hope so. Well other than that the application does what it says. It reports that my speeds are about 100MB slower than my third-party SSD manufacturer has advertised on the box, but I am not surprised that they probably used their best case scenario. At least this benchmark is fairly consistent with the various reviewers of my SSD model, whom have used numerous other synthetic benchmarking applications. 3 stars for confirming that my 3rd party SSD was an excellent purchase.

A+

Reliable and very accurate for testing any and all HD/SSD combination both internal and external. A++ Keep up the good work. :)

doesnt read, read speeds properly

i installed a 64gb crucial m4 in my 2.3ghz 2011 mac mini. and tried to run this. it ran normaly for the write speeds, but when it came to read, it gave me an automatic 15! and skipped back to write. tried deleting, redownliding, restarting nothing helps. PLZ FIX!

Nice

A good app to know the read and write speeds of your hard disk especially good for comparisons if you are thinking to install an SSD on your mac and remove the already installed HDD.

It’s OK.

Works fine with internal SSD but can not show correct speed for my Lacie moblie hard drive (2.5 inch). As other mentioned, it will alwasy show 15 for my external hard drive. Also the UI is too big for rMBP 13 although you can drag it and the data can’t see dont matter too much.

Crashes on OSX 10.9.1 when selecting drive

Works well with the default drive, but as soon as we try selecting a drive it crashes.

confusing

I don’t get it , Will it stop on its own or what. I am testing USB Thumb drive and this thing keeps running and running like 10 min now. No explanation when it will sotp or anything.

nice!

This is good to check your drives before useing them to record to. This is not meant to check regular drives or thumb drives. This is to make sure a SSD Drive is fast enought to recored video to with the black magic shuttle recorders. each format needs different requirements, this lets you know if it will record the format you desire before starting a shoot and having the SSD drive fail due to slow wright speeds. Not to check how fast you macbook hard drive speed. As far as the repeating the tests, they tell you that in the description, it is to indue that it will keep that speed or slow down and fail after a short time, again just so you know before starting a video shoot.

Crashes when selecting target drive

I’m running OSX version 10.9.5 and the app crashes every time I click “Select Target Drive”. I appreciate that it’s free but it’s currently unusable.

Works Like a Charm!

First time I used it, I couldn’t change drives to test. After clicking the Start button again, it also acts as a Stop button, then the tiny gear appears above it so you can choose another drive. Tested all my drives, everything worked flawlessly. Sure the speed gauges are big but if they were too small people would complain about that too. I had to adjust the the number of gigs for the drive to be tested in the pull down menu to get the readings for each drive. My SSD drive is off the charts fast while USB is slower than pouring molasses in Siberia. Great app, even better price! Thanks Black Magic

Max out by latest Jetdrive.

Recently I upgraded my macbook air from 128GB Samsung SSD to jetdrive 500. Read speed are max out(+500MB/s). This good app definitely needs an upgrade.

4K Video + External Drives

Needs to add support for determining ability to read/write 4K video. Improve performance for examining external drives.

2.2.2 still crashing

Version 2.2 had worked worked on my system (Mac Pro tower OS X 10.9.5) until recently, but recently the app crashes any time I try to select another target drive. Works fine on startup disk. So, installed 2.2.2. Works fine on startup disk, but immediately crashes when attempting to select another target disk.

Easy to use

I think this is the simplest app for measuring hard drive performance on the Mac.

Seriously?

The UI doesnt fit in my 720p macbook and there is no way to scroll down. Seriously fellas?

Crashing

Just installed this onto my macbook 3,1 with SNow leopard. It crashes, refuses to even open.

Does not work as told on 10.6.8 :-(

Why?

Wow… great… thanks!

I had a few older external hard drives that I wanted to connect to my brand new iMac 27” Retina 5k running OS X El Capitan. I didn’t want to slow down my system by connecting some older technology but didn’t know how to go about testing the drives. So I googled my question, and found this little puppy. After downloading version 2.2.2 and running the read/write tests, I realized my older Seagate external drive was still pretty fast while my Iomega was dreadfully slow… so, dumpster for that one. Thanks BlackMagic! (This is not an infomercial nor am I in any way associated with the company that distributes this product… I’m just just a happy customer.) By the way, it took only seconds to download and launch. And it’s free... How good is that!
