Ottima scheda cf fast 2.0. L'ho comprata per la 1dx mark ii ed è veloce e il buffering quasi non si vede. I Video in 4k che riescono con 128 gb sono quasi mezz'ora. Ottima memori

Expensive, but less expensive than others. You will get ca. 60mins of recording time when shooting 4K at 300 Mb/s. Need to buy more of these. Recommended.

Quality is superb

So far so good:the card holds up and frees my gimbal from any external SSD.Great value !

I was a bit skeptical about this product to be honest. I kept hearing that they were unreliable and that I'd be taking a risk. So I went ahead and tried it for myself and its been going strong. No issues, quite reliable and fast when it comes to transferring files compared to an SD card. I feel that I made the right decision choosing this card.

Great for use in Blackmagic cameras!

Really great for the higher compression options on the BMPCC 6k. Personally, though I have a large fast USB-C drive for the BMPCC, I love the ease of putting a Cfast card in cam. Less rigging, less wires coming off the camera. This card fits the bill almost perfectly, I’ve had great results at Blackmagic raw 8:1 and 12:1 with no issues even at 60fps (using 5.7k). However at the 3:1 compression ratio I have had the camera stop recording within 20 seconds, and I haven’t extensively tested the 5:1 compression ratio. My conclusion is this card is a great, relatively fast daily driver for the higher compression ratios, but if you need max quality you’ll need to pay for a higher priced card or go USB-C

It's not the fastest CFAST card in the market, but it's fast enough for the Canon 1DX Mark 2 for both videos (4k 60 fps) and photos (haven't hit the buffer at all yet). It's reliable, priced right, and it just works. Just bought another one! Highly recommended!

This card is a great deal. I do a lot of videos on my two Canon xc15 cameras. Never any errors on any of the settings. I mostly record at 4K 305mb and videos are typically an hour or longer and they are recording continuously. My other cards I use are 128GB and they won’t make it to the 1hour mark and costed about the same .

Great card, works well in my BMPCC4K!! Shooting in 1080p prores, and 4k BM-raw 8x works fine. Love this card and amazing for the price 139.UPDATE: have had the card for a little while now and still running strong, no errors, dropped frames, no issues what-so-ever. As soon as the price drops to 139 or less, I'll get another one.Update 12/2021Still using this card and running like a champ. No issues. Have bought more of them and only had an issue with one, it is slower than the others and drops a frame here and there. I marked it as a back up. Also I now use a blackmagic 4.6k and the cards still work fine in that camera, at medium compression ratios. Great card for the $$.

I shoot weddings on the 1dx mark ii and I prefer to shoot in 4k 60p which eats through data like no other. Having multiple cards is a must. This card at its price point has allowed me to have 4 cards on stand by which is a game changer.So far they have been very reliable. No issues. Bye bye Sandisk's 400$ ridiculous price tag.

PROS:Price is great.Formats in the camera with no problems.No files showed dropped frames or anything when shooting UHD BRAW 12:1 with a lot of zooming and panning in the project. It held up just fine for 2 days of shooting that tv show.CONS:The write speed limits the ability to record lossless RAW codecs above 2k resolution. Details below.About the photos. The screen shows the red record circle changing to a gray circle with an exclamation point after 14 seconds of recording Lossless Cinema DNG at 4.6k. The other photo is simply an image of the card in the camera.My experience and further details below.Bought this for a shoot in which I was using a 4.6k Ursa Mini Pro. The fine print and what matters most on this card is the Read/Write Speeds. I was shooting the BRaw Codec at UHD using a constant bitrate and 12:1 quality. That's as low as you can go but it is a much better image than ProRes LT or Proxy. This is a brand new codec and shooting RAW I was able to record 140 minutes on this 256 GB card. It worked out great! We could use 1 card for the entire day of shooting scenes of a corporate video that was stylized as a version of "The Office" so lots of pans and snap zooms and longish takes of a minute or 2 minutes at times. The card worked flawlessly. So if you are shooting on a camera that has access to a high resolution low bitrate recording mode then this card will be fine.HOWEVER. I just did some quick and informal tests to make this a more valuable review. It will not record 4.6k lossless in something like ProRes or Cinema DNG for extended takes. When recording at those flavors in 60fps or 30fps the card failed after 14 seconds or 40 seconds depending on the codec.When recording Cinema DNG at 4:1 ratio and 4.6K resolution it recorded for 1 minute without fail. It also records Pro Res 4444 up to 4.6k for for up to 1 minute. This is not an extensive test but I figure if it will record for more than 1 minute without card failure then the card is usable for that codec/compression ratio/resolution. The only codec that could record lossless / RAW 4.6k / 60fps on this card was Blackmagic Raw.Conclusion:If you get this card do your research and find out how many MB/s you need for your camera to record while making the project work the way you want in post. If you're doing anything that requires above 2k high resolution with high speed lossless recording then this is not the card for you. However if you have the ability to record lower bitrates at above 2K like BRaw or ProRes Proxy/LT and that works for your project then this card should be able to save you some money and get the job done.For this price I'd say it is a great value and useful card for those who have the right projects or cameras to maximize the cards capabilities. It's not a 5 star review because you can't go crazy shooting lossless in any flavor with this card so you are limited by it's write speed.

CFast 2.0 cards are super expensive and some of the less expensive options are not very reliable. I put the Silicon Power CFast 2.0 card into my 1Dx2 and it formatted just fine. I set it up to record 4K60 Video and let it fill up the card then formatted and did that 3 times. It ran great without a hitch. At the price of $199 for 256GB CFast 2.0 is a steal! I will report back with further usage. The Black Magic Disk Speed test was checked through an external card reader to a USB 3 port.
