List of approved CFast Cards

How about the FreeTail 3700x Cfast cards? They appear to be the least expensive and claim they hit the same speeds as the rest of these companies?

Is there any testing in progress?

Those prices are tempting, though after shooting 4:1 RAW 60fps I don't want a card smaller than 512GB and that company only goes up to 256GB.

512GB CFast 2.0

I'm wary of a company who has a card they claim goes more than 10% faster than the theoretical speed limit of SATA...

With sustained write speeds of only 130 MB/s, I don’t think these new G Series CFast 2 cards from Sony are suitable for the URSA family.

128GB max? 512GB or bust. This 4K60p RAW 4:1 is chunky

Christopher, like your attitude. Remember though for raw, you can record to two cards so the data rate to a given card is then half what you would need if you were recording to a single card. When recording to two cards, the even numbered frames go to one card and the odd numbered frames go to the other card.

Thanks Rick, on that note I'll go dual 512GB cards

Which by the way I ordered the 512GB CFast 2.0 from Egodisk last night and will report back the Blackmagic Speed Test results + any dropped frames with 4K60p CDNG, 3:1 and 4:1. Probably will arrive next Friday.

Happy Holidays all!

You know more about those Egodisk cards than I do. I stay with cards on the approved list but they are considerably more expensive.

Just because one card from a manufacturer is on the list, doesn't mean that different similar models and different capacities from the same manufacturer will pass. Even if it lists that it is higher speed.

Not all card media are created equal.

We only list cards that we have tested extensively and certified for recording footage continuously on our cameras.

As Tim mentioned - we were not able to send the 256GB 3700x card as were out on stock at that time. All our 3700X cards have been successfully been tested on the cameras. You can check some reviews on Amazon USa and Amazon UK

We had a firmware update in Q1 2017 that fixed all old bugs. All cards in global market is with the latest firmware.

Please feel free to send through the 3700x cards when they become available, as requested, but we can not add them to the list until we have run them through our full certification process.

Did some tests with the EgoDisk 512GB Elite Pro:

No dropped frames with RAW 4K60p 4:1 and 3:1.
But frames start dropping after a few seconds of RAW Lossless 4K60p

Rest of the findings are at my Blog Post

I dont think any single card can do that.. that is 1.025MB/s (without the known compression for lossless), on an interface with a teoretical speed of 600MB/s..

Test with lower frameratea one by one, and work your way through what can be done, and what cannot be done.

And remember do the test with actually footage - not black lens cap shots. The data is compressed remember.. so test something that is very variable to flex tve muscles of the card to maximum!

Thanks for the feedback, Christopher. As Dennis mentioned, that’s normal for 60 fps at 4K which requires dual card recording in raw. ProRes can do it on a single card, but not lossless raw.

Yes the faster cards on the recommended list for 4K or 4.6K Lossless RAW can generally sustain up to 40 frames per second to a single card without dropping frames. Above that you are into burst speeds where a single card can sustain that data rate for five, ten or fifteen seconds before it maxes out.

Compressed 3:1 or 4:1 RAW at 60p to a single card is less of an issue for most cards, which is why we introduced those two options.

Thank you for chiming in Tim. I tested 4K60p RAW (4:1,3:1) again with footage that has constant motion with 'stop rec if card drops frame' enabled. No frames dropped until the card ran out with a single 512GB EgoDisk.

Thank you for your help.
Best Regards,
David

The following CFast 2.0 cards were added to the URSA supported list:

Transcend 128GB CFX650
Transcend 256GB CFX650

The Egodisk Elite Pro 256 GB CFAST Card 2.0, it's good for the Ursa Mini 4.6?

[Tim Schumann]

This card is not on the recommended list so no, we wouldn't recommend it.

and the Komputerbay Professional 3700 x 256 GB?

[Tony Rivera]

Here is the list of CFast cards that have cleared our approval for the URSA Cameras.

This link at the top of this thread will provide information on the cards that are approved.

Is there a supported CFast card list for the Pocket 4K yet?
I can't see it.

Why so slow - lack of response?

[Tony Rivera]

Other than the information provided in the Pocket Cinema Camera 4K manual currently, there is no list of media because the camera has not shipped at this time. Expect an update to the support page regarding media when it does start to ship.

Thanks.
I just saw some 'open box' Cfast on offer and would rather buy something discounted than a full price CFast on the day my Pocket ships.

Wondering how the approved cards perform with BRAW. Gearing up for a feature and trying to decide on media. It seems that the approved card list indicates that there are no CFast cards that support 4.6k RAW. Is that correct for the old DNG RAW and BRAW? Or should I just resign myself to the SSD adapter? I want to avoid that so I don't add more weight to the camera for Movi shots.

Hi Tony, wondered if a Blackmagic Design list has been made up as yet.

Thanks…

We are in the process of certifying cards for Blackmagic RAW at the moment.

If you select any of the cards that are on the list for URSA Mini at 4K Lossless RAW 30p then these will cope with any of the Blackmagic RAW variants easily.

Hi everyone, I'm about to get an URSA mini pro 4.6k and I wonder if these Cfast Cards can hold the use on it.
ProGrade Digital 256GB CFast 2.0 Memory Card. the have a very fair price and the info they have seems to match the others Cfast cards you recommend. any idea?? thanks

This $129 256gb Cfast card on Amazon (prime even) claims to be certified by Blackmagic. Yet it's not on the approved list. Is it true? or too good to be true? https://www.amazon.com/dp/B079WMSV8Q/?c ... merReviews

Yes the ProGrade Digital cards are on the certified lists for the Mini Pro.

Card list updated for CFast and SD cards for Blackmagic RAW today -

Hi Tim,

Do you happen to know if the new 1 TB Angelbird Cfast cards are compatible with the UMP?

I noticed the 256 GB and 512 GB are listed as compatible. Hoping the 1 TB wouldn't have any issues. This is the data from their website which seems to be copied/pasted in the specs for all their capacities:

SEQUENTIAL READ SPEED: 550 MB/s
SUSTAINED READ SPEED: 530 MB/s
SEQUENTIAL WRITE SPEED: 450 MB/s
SUSTAINED WRITE SPEED: 430 MB/s

And just to confirm, the 256/512 shouldn't have any issue recording any flavor of Blackmagic RAW? Really hoping the same is true for the 1TB as the price is right and there is a decent discount going around on these cards for a few weeks.

Thanks for any insight.

Take care,

Mark

I don't believe we've had a chance to test the 1TB Angelbird cards yet so they are not on the list.

If the ones you mention are listed on the 4.6K Blackmagic RAW 3:1 up to 60p list then they should work with anything. The Constant Quality 4.6K Blackmagic RAW Q0 option may still see some dropped frames on frame rates of 50p and above on these cards but only for very, very, very complex and difficult to compress scenes with lots of fine moving detail but this is unlikely to happen in real world shooting scenarios.

Thanks Tim. Just to confirm: the Angelbird cards are not listed to work with Blackmagic RAW. However, they were listed as compatible for "recording 2160p Lossless RAW up to 30 fps". I thought I read earlier in this thread that if anything is listed as handling 4096x2160 Lossless RAW then it should be able to handle any flavor of BRAW at the full 4.6K resolution. Is that correct? Thanks again, Mark

Is this list accurate for the Pocket 4K too?
Has the Delkin Device 256GB card DDCFST560256 been tested by BMD?

I'm waiting for my Ursa Mini Pro to arrive later this week, meanwhile I ordered two Sony CFast 2.0 G Series CAT-G32 (32gb) that were on sale, and although they aren't on the recommended cards list their bigger brothers are, namely the CAT-G64 (64gb) and CAT-G128 (128gb) versions.

They all have the same write and record speeds, namely 510 MB/s and 530 MB/s, so I guessed these would work.

Has someone shot with these specific 32gb cards? I haven't opened them yet, I would like to be sure first so I can return them in case they aren't as reliable as the bigger cards.

I have a pair of CFast 2.0 Transcend CFX650/128 GB that my Ursa Mini Pro Can't recognize at any resolution. Thoughts?
