Just finished the 5h+ test (until full charged battery died). I used Hoodman Steel 1000x 64gb card. Writing speed 95% of the time was over 100mb/s. It dropped under 100mb/s only when the screen went to sleep, but when I got it back, speed returned back to over 100mb/s. Not sure why it happened.

Here are the file/results:

Please do let me know if that helps or if you need any other tests. I would love to help as much as I can.

Wow, it overlaps perfectly with the other Lexar from Jason Montalvo.

Glad to hear that :) I will be getting 4 more 64gb Hoodman cards pretty soon. I can test those to see if there is any significant difference in writing speed between same cards. I know for sure that hoodman quality control/check is top notch, so I expect them to have relatively same speed with not much difference.

The only issue I see is that I still can't record continues 1920x1280 even though card tops out up to 116mb/s writing speed, and 1920x1280 requires only 98mb/s. I think it's comes more to firmware tweaking and getting max out of it or as much as possible. Basically, optimization.

I've only used the log files created outside LiveView, so the results should be comparable.

nice to see the information out on the chart
im noticing that my two transcend benchmarks have a difference of about 10MB/s but by doing the partition alignment

Ill go ahead and rerun the benchmarks with different alignments to see how the results vary

So I'm finding that the 5D Mark 2 and 5D Mark 3 with the built in formatting will format CF cards to FAT32 with an offset of 31K and I believe an allocation of 16K

31K of course making the CF card not aligned..aligning the partition with an offset of 32K with an allocation of 16K appears to be giving me a ~10MB/s read speed increase but a ~10MB/s write decrease

FAT32 seems to be easier for me to troubleshoot myself seeing as there are way less options
I'll keep messing with it

with these tests I was reading a forum that was saying a 1024 offset was a good start point and a 64K allocation would give performance increases, curious as to how these benchmarks compare to my last benchmark

I wonder if the person submitting 64gb komputerbay had it in lv-mode or just playback.

cause LV Photo maxes out at around 98mb/s
playback mode 121mb/s

A1ex what mode are we suppose to try in? so people are clear on that.

You can check from logs. I've selected only the tests that were ran outside LiveView.

Just got the Toshiba 1066x 64Gb card.  Here's the real world sustained test results with the 18/5 build. I got bored shooting my foot after 9Gb.

1928x1180 24p @ 90MB/s
1440x672 48p @ 77MB/s
1120x640 60p @70MB/s dropped frame @ 2300 frames.

I'll run the new benchmark test this arvo.

Wanted to see how differently cards performed on different cameras
The cards were setup to have default formatting
by default I mean I took the card, formatted it in the camera, loaded magic lantern onto the card, and then ran the benchmark..no tricks

For some reason it seemed like the 5D Mark 3 was having slower speeds with the SD vs the 550D

I have tested the Toshiba 1066x 32 GB card with the build 19th.may on the Mark III. This is the log of the buffer size benchmark:

Toshiba 1066x 64Gb ex-fat

Why is yours so fast? Because you're in playback mode?
Mine only makes between 82-95

Yes i do. Mine came in FAT32 and i tryed to format it exFAT on MAC and PC. It didn't made it faster anyway...
http://www.magiclantern.fm/forum/index.php?topic=5513.0

There is one thing i still don't understand about the write buffer thing...is it possible to define the write buffersize somewhere in Magic Lantern? How and where?

AndreasK

How are you running the benchmark?

In photomode i get ~15mb/sec more then in videomode (that opens in liveview)...
