Got my FreeTail 256GB CFast. I let the C200 record it to full a few times and it works as you'd expect. Same with the ProGrades.
My FreeTail is metal top and bottom with plastic sides, just like all my other Compact Flash and CFast. At least I believe so. I’ll look when I get home.


Also, here's a pic of the FreeTail and ProGrade cards. Interestingly, the "branding" label is on the back/bottom of the FreeTail (and the front is blank). Similar to the Transcend CFX600s I used with my C300 Mark II. So, the empty side is "up" in the card reader. Not a big deal.
Construction on the two is the same... I imagine it's similar to the EgoDisk.

Yeah. I’m shooting a passion project in the next few weeks that I could always reshoot if necessary... so I’ll give them a workout and report back. If all goes well, I’ll likely snag at least one more FreeTail. $175 is a steal.

Thanks for the feedback. As far as I know, cheap cards use second choice memory. But it seems this is not always true. ProGrade look very fine to me.
I can only tell you that a computer engineer who shall remain unnamed once told me that all of the non-Sandisk cards probably buy rejected 512GB memory from whomever Sandisk buys the chips from. Theese inexpensive cards possibly use these second rate 512GB chips and map out the faulty sectors which is how we end up with low cost 256GB cards. Makes sense to me. Why else would Sandisk charge and get $1,000.00 for the same card that everyone is selling for $179.00 to $300.00? There is no free ride and from what I am told, like most things in electronics, the raw components all come from just a few manufacturers. A company like Egodisk or Prograde buys the memory chips and they supply/make their own enclosure and RAID controller. If these are like P2 cards, they have two to four memory chips that are hardware raided together inside the enclosure. As we have all been saying, it's all about risk assesment and redundancy is ALWAYS a good idea. Even shooting 2k proxy is a safety measure for me. Not as good as RAW obviously but good enough for a lot things.
They may not even be buying rejected 512GB chips... they may just be happy with a much lower markup than SanDisk is.
SanDisk is a luxury brand... like Apple. They charge $1000 for a 512GB CFast largely because they can... just like Apple charges a hefty premium for the collection of chips and components that go into a MacBook Pro vs. buying those same parts in a no-name brand computer.
I’ve done two shoots on mine now... one to full, the other it was the second card so it only got about 3/4 full. Both shoots made it back to the computer with no drama.
I am not aware of any specific limitations when using cards in the vicinity of 512 GB. I believe the reason you probably don't see them on the list is because, like you mentioned, it was released in a time before cards that size were industry standard.
Please allow me to inform you that your CFast card is supported by your camera [the C200]... This card will work fine with your camera.
While technically our AV PRO CF 512GB cards are compatible with the Canon C200 we did see some strange issues, yes. From time to time the C200 won't detect cards that are already formatted, requiring the user to insert the card multiple times for the camera to successfully establish a link to the card. This will NOT happen if the cards are 'empty' although.
Our engineering lab confirms ProGrade Digital CFast 512GB memory cards perform flawlessly across all benchmark testing on the Canon EOS C200 Cinema Camera.
Regarding your question, actually, we don’t really test it on Canon C200. However, the performance of our CFX310 512GB is R: up to 529 MB/s, W: up to 198 MB/s (based on card reader), also you could refer to the detailed specification of our CFX310 512GB as below to make sure if it meets your request. https://www.silicon-power.com/web/product-CFX310
