ProGrade Digital Memory Card - CFexpress 4.0 Type B for Cameras | Optimized for Express Transfer of Files & Large Storage | 512GB Gold Series | Read speed up to 3400MB/s and write speed up to 3000MB/s for RAW photo bursts and 8K, 6K, and 4K video recording

I have been using ProGrade SD cards for a while and only buy ProGrade for reliability, so upgrading to their CFexpress 4.0 cards for my RED Komodo X was an easy decision. The speed difference is immediately noticeable. Fastest cards I have ever used, and consistent with it. No dropped frames, no hesitation. Two things worth knowing before you buy. First, you need a compatible CFexpress 4.0 card reader to actually hit the read and write speeds, so factor that into your setup. Second, the price is steep, though SD card prices have risen so much lately that the gap feels smaller than it used to. If you shoot on a RED or any camera that supports CFexpress 4.0, these are the cards to get. ProGrade continues to deliver.

I've been using these 1TB Gold cards in my Canon R5 Mk I and II for video for around a year now. Performance is great - it even copes with recording 8K RAW footage on my R5 II with no issues at all. The cost is reasonable too given the large storage capacity.

Fantastic memory card that's not failed once. Fast enough to keep up with 4k 100fps no issues. Highly recommend.

I bought the card over a week ago and its a really good card 240gb i wish id bought another for the price i paid as its gone up now. Its an Ideal Card for the new Mirrorless cameras out there on the market that need the faster read and write speeds easy to use and installed in seconds to my Nikon Z8

I’m using this card with the Nikon’s Z8 camera. If you are happy to use the camera in the compressed raw HE* mode rather than uncompressed raw then I fully recommend this card. For videographer, all of Nikons video codecs work with this card. In addition, if used with a version 4.0 card reader and thunderbolt equipped computer, you will get the benefits of faster upload transfer rates. When capturing uncompressed raw images in burst mode this card captures about 70 images at 20 fps before the image buffer fills. At that point it continues to record at about 10fps until the card is full. Using the compressed raw HE* mode one can capture an over 200 images before the buffer fills. Once the buffer is filled and shooting stops it is cleared pretty quickly allowing one to shoot at full speed again. This card is a version 4.0 card but there are currently no cameras that support this specification. The card does work in current cameras but at half the specified speed. This card is advertised with a read speed of 3400MB/S and a sustained wite speed of 2400MB/S leading one to believe images can be captured at full speed and without buffering issues. What’s more confusing is that the label on the card indicates a sustained write speed of 850MB/S which is at the bottom end of acceptability. ProGrade’s web site indicates that they have changed their benchmark algorithms and as a result have changed the sustained write speeds. These new figures are misleading and are out of line with the rest of the industry making it difficult for consumers to compare products on a like for like basis.

Excellent, I'm sure my photos have improved using this card. I've used this card in burst mode taking many shots together. The quality throughout is very pleasing.

So far fast enough to enable camera to clear buffer without missing a shot at reasonable price

Excellent product I will definitely buy again

Une carte mémoire exceptionnelle pour photographes et vidéastes exigeants J'utilise cette carte ProGrade Gold CFexpress Type B 512 Go depuis plusieurs mois, et je suis absolument conquis ! Que ce soit avec mon Canon R5 ou mon Fujifilm X-H2S, elle offre des performances remarquables. En photo, les rafales s'enchaînent sans aucune limitation. La vitesse d'écriture est tellement rapide que je n'ai jamais eu le moindre ralentissement, même lors de séances sportives ou animalières intensives. En vidéo, c'est tout aussi impressionnant. Les enregistrements en ProRes, raw 8k, 4K 120, aucun soucis,sans aucune interruption ni perte de données. La carte supporte tous les formats sans sourciller. Son prix est certes élevé, mais pour un professionnel, c'est un investissement qui en vaut vraiment la peine. La fiabilité et les performances sont au rendez-vous. Recommandation : un must have pour les photographes et vidéastes exigeants !

Da fotografo professionista, l’affidabilità e la velocità delle schede di memoria sono fondamentali per il mio lavoro. Gestisco quotidianamente file RAW molto pesanti, video in 4K e ho bisogno di un supporto che mi permetta di lavorare senza interruzioni e senza timori di perdita di dati. La ProGrade Digital 512GB CFexpress Type B Gold ha superato ogni mia aspettativa. Appena inserita nella fotocamera, si percepisce subito la differenza: la velocità di scrittura e lettura è davvero impressionante e consente di trasferire i file sul computer in pochi istanti. È una scheda progettata per chi lavora con ritmi intensi e necessita di performance costanti, anche durante lunghe sessioni di scatto o registrazione video. La capacità da 512 GB è perfetta per coprire intere giornate di lavoro (nel mio caso matrimoni e sessioni di shooting) senza dover cambiare scheda. La costruzione è solida, con materiali di alta qualità che trasmettono sicurezza e durata nel tempo. Durante l’utilizzo non ho mai riscontrato surriscaldamenti o rallentamenti, nemmeno con raffiche prolungate o registrazioni video ad altissima risoluzione. Un altro aspetto che ho apprezzato è la stabilità nelle prestazioni: la scheda mantiene velocità elevate in modo costante, senza cali improvvisi, cosa fondamentale quando si lavora con flussi professionali. Il prezzo è leggermente superiore rispetto a modelli più economici, ma per chi lavora in ambito fotografico o video professionale vale ogni euro. È una di quelle schede che ispirano fiducia e ti permettono di concentrarti solo sul lavoro, senza pensare alla memoria. Per me, la ProGrade Digital CFexpress Type B Gold da 512 GB è una scelta eccellente per chi cerca velocità, affidabilità e qualità costruttiva. Dopo settimane di utilizzo intenso, posso dire che è diventata la mia scheda di riferimento per ogni progetto.

ProGrade Digital CFexpress 4.0 Typ B Ich verwende (täglich) die Karte in der Nikon Z8 seit einem Jahr und habe bislang keine Probleme mit der Karte. Schnell und zuverlässig. Würde ich wieder kaufen.

Good card that runs without overheating in my Nikon Z8 camera.

They don't overheat in my Nikon. ProGrade is 2 levels above Sandisk and Lexar.
