Transcend TS256GCFE820 CFexpress 820 Type B Memory Card for 4K Video Capture Ultra-Fast Transfer Speed of 1700 MB/s

I've used it for my camera Panasonic Lumix Gh6 and after formatting in the camera it's working fine. Plenty of space for this price. Write/Read with the camera is very fast, and when transferring photos to Laptop using card reader is bullet fast. Highly recommended!

I faced problem with reading and writing of card from pc it was very slow.

excelente producto en relación calidad-precio

Update: 2023-October-16I've had a chance to use the card and test its performance. The screenshot shows the transfer rates I got when using a CFE card reader (Amazon SKU B0BJVKBFYM) with a ASM236X chipset. Based on the speeds, I suspect this is the ASM2362 chipset, which only supports 10Gbps speeds. So it's possible that this is the limiting factor in the noted read/write speeds shown in my picture. My testing system has USB 4.0, so that was not the limitation.That being said, the card get VERY hot! And after about 45 minutes of 4K/60 video recording, the EOS R3 automatically shutdown due to thermal temps getting too high. The same heat was generated when running the benchmark in the external card reader. I don't know if this heat is indicative to this particular card or to CFE cards in general. Based on what I know about memory cards, the heat is probably typical of all highspeed CFE cards.I don't have much reason to doubt that the card gets near its claimed read/write speeds. As noted, the only issue I had was heat related. Capturing sustained video streams of 4K 60fps posed no problems.Original Review:The price was very competitive and I've been very happy with Transcend products in the past. I've had no issues with it in my Canon R3. I cannot report on the actual transfer speeds outside the camera because I don't have an external CFexpress card reader. I can only say that the camera hasn't given any issues or warnings regarding performance.

Photographe professionnel, je fais confiance à Transcend depuis près de 10 ans. Je n'ai jamais été déçu et n'ai encore jamais eu de carte défaillante avec cette marque (je touche du bois). J'ai donc suivi Transcend pour le passage de mes Nikon Z6II en CFexpress. Rapide, solide, de grande capacité, et enfin à prix abordable : pour mon usage, tout est parfait. Il y a maintenant un peu plus rapide, mais beaucoup plus cher. Cette carte est un excellent compromis.

Guess these will come down in price in time but at the time of purchase (2023/12) seem to be a good compromise between the two. They are also from a known brand I have used before.Also purchased another top brand and can't really tell any difference in performance. Maybe if shooting video at 8k, but at 4k is more than enough for me!Would I buy again - probably

Got this for my z8. I have the equivalent 356gb prograde and this is just as fast for 30 frame bursts at full raw or 8k video. Good value for this level of performance.
