Just ran a new test, with Global Draw disabled I get continuous rec. and
- Reported write speed: ~89 MB/s CF, ~60 MB/s SD, total ~148 MB/s
- Actual write speed (calculated from final MLV file size): 90.1 MB/s CF, 60.7 MB/s SD, total 150.8 MB/s
So reported write speed looks pretty reliable to me, at least on my 5D3.
Also, I do not understand if my results are in line with your expectation. When you say "in LiveView" you mean with Global Draw enabled, right? So cannot compare these with your 135 MB/s I guess.
Thanks for your clarifications

Thanks for running the test.
To check write speed accurately with RAW video recording:
-Make sure your recording is continuous, at least record 4 minutes, this way we can ignore buffer impact on write speed or at least minimize it
-Share your FPS, number of recorded frames, MLV and M00 files sizes in bytes
-If you want to use Lossless, make sure your scene is 100% static in a controlled environment
LiveView and Global Draw are two different things. Pretty sure you already know what
LiveView means. When I say in LiveView, Global Draw can be either disabled or enabled, for my test it was disabled.
I will redo my tests again to double check, also I will use 1.1.3 version instead of 1.2.3, because all my tests were using 1.2.3.
