Realtime Hard Disk Monitor
Can anyone recommend a decent hard disk realtime performance monitor for Windows? The built-in Resource Monitor doesn't quite cut it. I'm looking for something that will show me, per drive, my read/write performance. I need to test some software that has bandwidth throttling for network/disk and I need to verify that it's really writing at the speed it says it is. Google has been mostly fruitless with a ton of crapware to show you your SMART values.
To answer my own question, I never did find a small, simple util to show what I need so I ended up just using Performance Monitor. Select the PhysicalDisk - Disk Writes/sec counter and set the mode to Report.
Have you considered using Windows Gadgets?
Take a look at Drive Meter Gadget, I believe it might meet your needs.
I have such a gadget at home (or at least I used to), but for work all my testing is on Windows Server 2012R2 where the Sidebar is deprecated.
Doesn't the new Task Manager do this task already?
Close Task Manager.
Run an Elevated Command Prompt, enter: diskperf -Y
Open Task Manager, there should now be a Disk tab for each Drive under the Performance Tab.
I had looked at that but it didn't occur to me that you could add extra disk counters via a command-line. There sure wasn't a way to do it via its own form.
