Transcend CFexpress 820 Type B Memory Card TS512GCFE820

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.

- Hohe Lese- und Schreibgeschwindigkeit- Beim sequenziellen Lesen und Schreiben von großen Datemengen (hier ca. 400GB) wird die Karte recht heiß und die Schreib / Lesegeschwindigkeit fällt:- Beim Schreiben auf ca. 144MB/s- Beim Lesen auf ca. 650MB/sFür Hobby-Fotografen und Videos in 4k60 ist das mehr als reichlich. Die Werte stellen natürlich nur eine untere Grenze der wahren Dauer-R/W-Geschwindigkeit dar, die ggf. auch durch mein Kartenlesegerät begrenzt sein könnte.- Sicherheitshalber habe ich die Karte (Verkauf/Versand Amazon) mit f3 (Fight Flash Fraud) getestet - keine Auffälligkeiten, Karte ist in Ordnung.

Jag fotar huvudsakligen med Canon R5 och filmar ibland kortare klipp i 4k 50 fps - detta funkar kortet jättebra till. Det som inte funkar så bra är video med högre bitrate, t ex så toppar kortet ur vid:100 fps 4k: ca 31 sekunder8k RAW: ca 25 sekunderJag kan tycka det är lite märkligt eftersom 8k RAW bitrate är 2600 Mbps vilket motsvarar 325 MB/s - för 100 fps är det motsvarande 1880 Mbps (235 MB/s) - så kortet borde ju vara tillräckligt snabbt med sina 1000 MB/s i skrivhastighet.Pris vid köp: November 2023 för 1 405,52 kr
