C200: CFast compatability - Cards that support VPG-130

ashayafilms said:
Hey guys, just wanted to give you heads up. I got 2 of the New EgoDisk 512 Cfast cards and sometimes when booting up my C200 the cards fail to initialize. So basically I have to reboot the camera, and then they work fine. I've asked EgoDisk about this issue and their exact quote to me was: "Sorry to hear that , but we would like to inform you that it's C200 issue with any 512GB CFast 2.0 Cards". Not sure what to do now... They record fine but I wonder if it's really a Canon problem or if it's still them.

Thats interesting, their explanation sounds plausible, seems like the 512 cards are just coming out. The Ego Disk 256 cards I have been using have not given me any issues.
 
Just pulled the trigger on two 256's, but now looking for a reader. Other than G-tech EV series reader, which Lexar Cfast reader are you guys using? I noticed a CR1 and CR2.

Egodisk themselves strongly recommend NOT using a Lexar reader, there have been quite a few documented cases of the Lexar readers corrupting the files in ingest (I actually spoke with one of their engineers about it). I bought the Lexar CR2, it worked fine, but that same week, two or three other DVXUsers reported corrupted files using the Lexar readers. So I returned it and replaced it with the Sandisk reader, it's not Thunderbolt, it's USB 3.0, it's a little slower but so far, did a big two camera shoot in Atlanta a few weeks ago and we ended up downloading dozens of cards over a week with nary a glitch, hiccup or problem so I am more than happy with the Sandisk.

Ahhh...Thanks for the heads up. Once glitch is too many for me, especially if it's for client work. I'll give the sandisk or g-tech a go.
 
So, ~ $1.10/GB while Lexar is at still at ~ $2.65/GB. And it's Lexar that's going out of business.
 
Fortunately, it looks as if CFast 2.0 cards are becoming commoditized, thank goodness. Maybe we'll see 512 GB cards for $400.00 soon?

Honestly as great as it would be to have less expensive 512 cards, I'd be more excited to see $150 256GB cards. For me, 34 min is about the max I'd want to cram on to one card, because if it gets corrupted...

I hear you. I would like to have both, perhaps a couple of 512s for interviews and then half a dozen 256s? I just find 34 minutes sometimes interrupts the flow on a good interview. Choice is good.

Yeah for interviews I don't wan't to stop rolling, and if would probably record to an external as backup if budget allowed. For narrative (what I'm doing most of the time), 68 minutes could be a whole day of work... or at least the better part of a day (assuming 3 minute takes and only doing 3 takes per scene).

Just the thought of losing that much makes me queasy...

Which is why Micron got out of it. Proprietary formats such as X-point have much higher margins.

As to price trends, it's hard to predict CFast 2.0 specifically because CFExpress is on the horizon and card manufacturers may have to retool their fabs before commencing new production. Price trends are, naturally, negative in the electronics in general but these zigzags can result in temporary price hikes.

I believe, currently, only Delkin has a CFExpress card out. 8 GB/s is allegedly the target performance.

I still haven't seen these tons of reports of the Lexar CFast readers corrupting files anywhere but when talking about Egodisk cards on this thread (and the one posted by Fahnon about his files getting corrupted). I've had both the CR1 and CR2 for quite a while and have never had a corrupted file... but I don't use Egodisk cards.

I get that Egodisk recommends not using Lexar readers. That's fine... though I'm a little skeptical of an upstart CFast card that is that strongly against an extremely well-established brand's card reader that seems to work for everyone else's CFast cards just fine. I'd want more explanation about what exactly is out of spec (is it the card or the reader) that causes the corruption issues with Egodisk cards and Lexar CR-series readers before I ever trusted an Egodisk card with my data. I'd be interested in hearing what the Egodisk engineer told PD when he talked to him.

Other than this thread and the other one I mentioned above, a Google search for "lexar cr2 corruption" returns zilch or nearly zilch except people talking about how to recover CR2 files (Canon Raw stills) from corrupted memory cards.

I own two Lexar and two Sandisk CFast readers, and Lexar CFast cards. Haven't had issues with the readers. I just bought a couple Arri 256 GB CFast cards; $880 each. Ouch. Probably need to buy a few more too.

On Canon's webpage for the C300's approved media, it lists to use the "Lexar Sanitzation Tool" periodically on the Lexar cards which will help prevent buffer issues. I've found that I have to use the Lexar CFast reader to use that tool, as it is not recognized while using the Sandisk CFast readers. Other than that, the Sandisk readers work fine with the Lexar cards. The Sandisk reader is smaller, so it's got that advantage over the Lexar.

I'm experiencing problems with CR1 reader and windows 10 (no corrupted files yet) reader just keeps disconnecting, on my old laptop it works ok.
 
To be fair, the 30 days I had the Lexar CR2 reader, I didn't experience any corrupted files. I thought the same thing, who is EgoDisk and why would they so vehemently recommend not using a Lexar reader? But I did read the Amazon reviews and did see at least two of the posters here saying they had corrupted files. The engineer at EgoDisk I spoke with didn't give me the technical reasons why the Lexar readers are thought to corrupt the files but I did experence something like this when I was shooting P2 cards years ago. Using the recommended Panasonic P2 reader, for some reason, the Apple OS was writing weird, corrupting data header strings back to a P2 card that had mere been inserted into the reader. Different issue than this but it made me very cautious about any kind of card reading issues as I was screwed over once with the corrupted P2 data issue. So far, no issues with the Sandisk reader and the EgoDisk cards. I am shooting the 2K proxies so as far as clients, a CFast data loss would be bad but not hopeless as the 2K proxies look decent, but it could be a problem if our client were delivering a 4K master.

For me, I felt better safe than sorry and returned the Lexar CR2 reader to Amazon and picked up the Sandisk reader. I really didn't have the time to do exhaustives test sequences over and over comparing the Lexar reader to the Sandisk as my 30 days for return was up. As far as EgoDisk cards, so far, they have behaved well. Fingers crossed and I am going to continue testing with them and shooting with them. I cannot afford $4k worth of Sandisk CFast 2.0 cards for my camera, but I can afford to buy a 256 GB EgoDisk card each month or so until I have 4 hours of Cinema RAW Light capability, which is my goal for the C200.
 
Angelbird's CFast 2.0 are available at Adorama for about $1.5/GB. I s'ppose if one's maxing out CFast 2.0 bit rate on URSA, ARRI or alike, then one could go for the higher end, yet still reasonably priced, cards. For Raw Light, EgoDisk seems to be fine for the time being.
