Here's the latest version of BMD's Disk Speed Test for Windows.
I extracted it from BMD Desktop Video v10.11.1 (also in v10.11.2).
Here's a download link (7.76MB).
Please ignore any ads, and just press the blue download button.
Mind you, there seems to be a bug with Intel SSDs in terms of read speeds, as illustrated in this screenshot.
Anyway, just extract and run it, no need to install.
Cheers.
