UHS-I / SD cards investigation

[ZEEK]

Testing the 512GB SanDisk Extreme PRO again @240Hz Patch, best card I've used to date. Tested in 1080 Mode 16:9, 10 Bit on the EOS M.

Photo Mode SD Benchmark:
Read: 105.9 MB/s
Write: 88.5 MB/s

Thanks for info, its at the price of the camera itself so ill pass on it for now but its interesting, it could maybe record in 3K 10 bit ?
Ill try to find cheaper alternative with similar specs

If you're a deciated ML user who travels a lot and shoots high resolution Video, it will definitely come in handy. I was hesitant at first, but now no regrets with this purchase.

Unfortunately 3K Raw on the M is max 18/20fps. 2.8K is the best Resolution so far.

With the 192Mhz patch I get about 5-12 Seconds, with the 240MHz patch, 1 Minute & above. Not sure about the consequences of using the highest patch and how taxing it can be on the card in long term use. Don't think it should be too bad.

Beautiful numbers Zeek.
Could we have a 5D3 tester with this card? Let me know if so.

A user reached to me last month with Sandisk Extreme PRO 64 GB 280 MB/s (The following photo sent by him):



-Unfortunately benchmarking this card at 240 MHz on 700D the speed would drop to 21 MB/s.

At 192 MHz it's fine:

One must avoid comparing different cards but this is what the 32 GB variety does:
https://www.cameramemoryspeed.com/reviews/sd-cards/sandisk-extreme-pro-280-mbs-uhs-ii-32gb-sdhc-memory-card/
One of the early UHS-II cards with serious speed limit in UHS-I compatibility mode. Not able to beat 50 MByte/s in UHS-I write mode.

If you are able to use a decent UHS-I reader you may be able to verify/falsify.

Hi Danne, I have the 512Gb x170 Sandisk SD and a 5d3 running 1.2.6, and am happy to test.

Just point me to the right build and tell me what to do, and I’ll post the results up here.

[Danne]

Great.
I need to prepare a build later tonight. However. You need firmware 1.1.3 or 1.2.3 to even be able and install magic lantern. Ever installed before?

[theBilalFakhouri]

Adding active cooling to the card might also work but doesn't seem very practical.  Might be interesting to see if overclocking is more reliable inside a fridge!  We might learn if heat is a real factor here.  Drill holes into the battery / card compartment in advance for best testing

Tested today Sandisk Extreme PRO 32 GB 95 MB/s with Canon 700D inside the fridge:

This card benchmarks 99 MB/s write speed in PLAY Mode compared to Sandisk Extreme PRO 170 MB/s card which benchmarks 90 MB/s write speed.

The speed never dropped to 21 MB/s , but at longer recording times the speed would drop and the recording would stop automagically, of course this is temporary drop, it didn't switch to safe mode (48 MHz mode) which gives 21 MB/s , starting another recording you will have full speed again until at some point it will stop automagically.

So yeah I think the card struggle with high frequency such as 240Mhz even if the temperature wouldn't be that high.

[Danne]

Tests with a 512gb card should be performed on 240Mb/s also on other cams then eos m.

[smasry]

Sorry, Danne, forgot my firmware version... it is 1.2.3.

And yes, I’ve been using ML for years now, am presently on your Nightly.2020Jul05.5D3123, as reported by the Magic Lantern launch menu.

[Danne]

Ok. Work only with sd card in your camera.

You are gonna need this build:
https://bitbucket.org/Dannephoto/magic-lantern_dannephoto_git/downloads/crop_rec_4k_mlv_snd_isogain_1x3_presets_2020Sep14.5D3123.zip

Replace the sd_uhs.mo to the one below:
https://bitbucket.org/Dannephoto/raw2mlv/downloads/sd_uhs.mo

Enable bench.mo. The rest of the modules will be enabled automatically.

1 - Enable the sd uhs patch called 240Mb/s and restart camera.
2 - Enter photo mode and run the 1 minute benchmark test. Are you getting high readings? Should be bitmap file on your sd card recorded.
3 - Now take a photo, then rerun benchmark test. Are you still having high numbers? If not your card will not respond well with 240Mb/s. If results still are high move on to step 4
4 - Enter movie movie mode. Start recording in anamorphic mode. Do about three to 5 takes. Everything orking as expected? If so, this card should be working with the patch.

Ok, Danne, done 1, results of step 2 are:

- Following step 2 from scratch: https://imgur.com/LoVts4q

3.
- Tried to take a photo, got a warning about card 2 being unavailable, followed by an Err 2 crash. Upon restart, deleted the photo (which *did* save), and reran step 2 with higher benchmark results: https://imgur.com/slAHOrB
- Just in case, I restarted the camera, deleted the new images, ran the benchmark, took two more photos, and reran the test with equally high results: https://imgur.com/bYnbncT

4.
- Entered movie mode, tried to record in anamorphic mode, got 'CARD FULL' error, over and over again. Tried restarting the camera, trying to record video failed again with the same message: https://imgur.com/8M5XF2T
- Trying to start a video after the card full failure message results in: https://imgur.com/BQJB1GO

- Eventually, after a few restarts, I was able to shoot a video for around 10 seconds, which then auto-stopped. Trying to take another video after resulted in the same 'CARD FULL' message.

[Danne]

Thanks. Confirmed not working. No further tests needed.

Wow, great to hear that recording with 240MHz is possible. Shame it requires such an expensive card. I watch your videos Zeek, I see that you have multiple EOSMs. Does this card work at 240MHz on multiple cameras?

With the 192Mhz patch I get about 5-12 Seconds, with the 240MHz patch, 1 Minute & above. Not sure about the consequences of using the highest patch and how taxing it can be on the card in long term use. Don't think it should be too bad.

These cards do have a lifetime warranty, don't be shy about frying your card for science

Yes indeed! I'm no rich guy, but after being an EOS M user for a few yeas now, I knew it was finally worth the jump Yes, it works on all my EOS M Cams.

These cards do have a lifetime warranty, don't be shy about frying your card for science

Haha, better not lose the receipt

Just bought a 700d for an extremely good price so I instantly set out to try and get raw video out of it. And I also just made my own account on this wonderful forum... I did so because I am having a pretty hard time getting the "sd_uhs" module to work on my t5i/700d. I tried everything, from installing other firmwares, to just plain formatting and starting fresh. I've been trying for about 6 hours just today just scouring various forums and different youtube videos, so I finally decided to cut the snake off at the head and just make an account.

If someone could give me the latest firmware for the 700d known to work with "sd_uhs.md" with download links, then that would be greatly appreciated!!

Best regards,
-Eli

An EOS M user tested Sandisk Extreme PRO 512 GB 170 MB/s with 240 MHz overclock, the 240 MHz overclock didn't work on that Card, benchmarks showed 20 MB/s

Some cards are lucky, like as ZEEK's Sandisk Extreme PRO 512 GB 170 MB/s card, unfortunately buying an Sandisk Extreme PRO 170 MB/s with 512 GB capacity isn't a guarantee to make 240MHz preset work on EOS M.

[Danne]

Yes, and after some more testing ZEEK also had some not so stable recordings with his 512gb card. He did some tests in a pm I sent.
I noticed also I am getting a few frames occasionally with 16:9 preset with full real time preview anamorphic. It only needs a little reducing of height to get fixed so I´ll test some more when I get the chance.

[Audionut]

I'm not entirely sure of what the status of this project is at currently. I don't have time to read 27 pages sorry.

I've moved this thread into the new section. I would appreciate if someone wants to take a leadership role with the creation of fancy OP, with updated build links, a short summary, that sort of thing.

Hehe, let the hazard begin  .  Great stuff.

[dinobike]

I've been a little out of touch with new advancements in ML, so i tried the latest uhs.mo improvements and was surprised with my "old" Sandisk extreme Pro 300mbs uhs-II that hits 80mb/s write speed @192mhz. With the previous version of uhs.mo the card was almost useless for raw video recording, but now im just so happy and still trying to figure out the new crop and binning records.
For now i'll be stuck with "normal" resolutions 1736x976, that looks incredible and gave new life to my 700D.

The benchmark was in photo mode.

New to the forum, here to post some findings. Just got my first Eos M and I have some sd/micro sd cards laying around, before I buy a new one I thought I would test them out first.

Samsung EVO select microsd 128GB,   160Mhz gives best results @ 54.5MB/s, which is enough for 1080p at 14bit, which is the only mode I need, this card runs about $20 on amazon.
Samsung EVO select microsd 256GB,   192Mhz gives best results @ 56MB/s, which is enough for 1080p at 14bit, this card currently sells at $35 on amazon, I got it when it was on sale at $25.
sandisk extreme Pro 95MB/s 32Gb,      192Mhz gives best results @ 44MB/s, just about barely enough for 1080p at 14bit.
SanDisk Ultra 64GB MicroSDXC, this card is a no no, it barely goes above 20MB/s, so not enough for magic lantern.
Patriot LX Series 64GB, slightly better than Sandisk Ultra, goes to about 28MB/s, still not enough for magic lantern.

So shooting at 1080p 16:9 at 14bit, you are gonna need at least 41 MB/S writing speed. A 64GB card is gonna give you around 20minutes of footage, 128GB 40min, 256GB 80min and so on so forth. Based on my personal experience, a 8-10 hours shooting day(story based short film), I usually get about 60-75 mins of actual footage on camera. So for me, 256GB is the minimum.

So if you are like me looking for a cheaper alternatives to the much praised but more expensive SanDisk Extreme PRO, samsung evo select is a pretty good contender, they are not as fast as Sandisk extreme pro, but  good enough for what I need.


Currently I'm waiting for a 256GB Samsung pro plus full size SD card to be delivered,  I got it when the price is marked down to $30 for 256GB size, not sure it's temporary or permanent. It's supposedly designed for 'professional' use so I expect it to be more durable and writes fast than the consumer grade EVO select. I will report back when I receive it.
