Our CFast 2.0 cards far exceed the minimum performance that other manufacturers strive for.

Our testing processes are far more time-consuming and rigorous than the sample testing done by other card manufacturers. When you choose ProGrade Digital you will have the highest level of assurance that your memory card will perform flawlessly.


With years of experience working closely with professional DSLR and video camera manufacturers, we’ve perfected our memory card compatibility and qualification tests. In our compatibility testing labs, we verify that the memory cards operate with thousands of different camera models and that they exceed the quality compliance minimums that manufacturers set.


We’ve always strongly believed that our customers come first, so, if at any time during your ownership of our memory cards you have issues, we will be right there to resolve them. Simply contact us and explain what you’re experiencing and our customer support team will quickly and efficiently assist you.


Our Refresh Pro Software provides memory card owners with the tools they need to maintain continuous high-performance of their memory cards. For uninterrupted high-speed photography and video capture, Refresh Pro performs both health monitoring and sanitizing. The health function measures the overall health of the memory card and provides feedback on the remaining life of the flash memory. The sanitize operation performs a deep clean, restoring the memory card to its original factory performance. Sanitize has been a function of CFast(TM) cards since they were introduced and ProGrade Digital now brings this functionality to SDXC(TM), microSD(TM) and CFexpress (TM) cards.

Find answers to your CFast 2.0 questions:

What is a CFast Card?

CFast 2.0 memory cards are based on SATA-3 and support bus speeds up to 600MB/s. The CompactFlash Association (CFA) is the organization responsible for the CFast specification along with other industry standards like CompactFlash(TM), XQD(TM) and CFexpress(TM). ProGrade Digital launched CFast 2.0 memory cards in Feb of 2018.

Which Cameras Use CFast Cards?

CFast cards have been used in video cameras from Canon, Black Magic, and ARRI. See the memory card compatibility sheets here for more detail on specific models.

Is CFast the Same as Compact Flash?

CFast and Compact Flash memory cards are often confused with each other because of their similar names and dimensions. However, the connectors for each card are completely different so they can not fit into the same devices. The Compact Flash standard was introduced in 1994 and has not been introduced in any new cameras for over a decade due to its speed and capacity limitations.

Does this work with the Ursa Mini Pro 4.6k?

Yes, the CFast 2.0 cards work with the Blackmagic Ursa Mini Pro 4.6K.

Is this compatible with BMPCC4K ?

Yes, the ProGrade Digital CFast cards are compatible with the Black Magic Pocket Cinema 4K. We have tested the camera in our lab and Black Magic has tested it as well. Also, ProGrade Digital cards are listed on the Black Magic site in the list of recommended cards.

Will these work on a Canon 1DX Mark II?

Yes, ProGrade Digital CFast 2.0 cards will work great with your Canon 1DX Mark II.

The fastest most reliable memory card I have ever bought
This has to be my favorite customer service experience I have ever had. I went on the website and found the product I wanted was sold out. I called the phone number on the website and Ed, the VP and Co-founder answered the phone. He was able to find out a new shipment was coming in the same day and had his warehouse set everything up for me to have it next day shipped. A very professional and kind person.

On top of this the quality of the memory cards are amazing, I have a GH5 and I needed the reliable read and write speed. These cards delivered perfectly for my trip to Bali. I will be buying more products from Prograde.

Thank you again Ed!


Different. Genuinely different.
This isn't just a private label. Somehow, they got a factory to tool up with an improved polymer, improved PCB, lower resistance, higher power handling...
I was wondering if these things were worth it, or even good at all. They are.
All the real specifications are right there in your face. No nonsense. You know precisely what it's going to do, and it's built to last and endure all those high data rate cycles.
People don't think about that. This stuff does wear, and heat is how it happens. This card can take a beating, and is worth every penny. I know where I'm getting my cards from now on.


Fast, Reliable Cards, Won't be Buying Any Other Brands
I've been a professional full-time photographer for more than ten years and I know that the most important thing from every shoot, the reason the clients are paying me, is for the photos and videos that I create from that shoot. Ever since the release of the Canon 5D Mk III, I've been duplicating data for my still images during every shoot, writing each image to two cards which made me feel confident that I'd never lose an image (and I never have), but this last year I started shooting video for clients and purchased the Canon EOS R, which only has one card slot. Since the content I produce is the most important thing and I could no longer duplicate it on the spot, I knew that I had to get the most reliable SD Cards I could. In the past I've used Lexar cards for my entire career, but from online reviews, it appears that their quality has gone down in the last few years (the company was also sold during this time), and I cannot afford the risk of losing any content. I had heard of Prograde from a friend, so I started researching them and through my research was convinced that they make superior cards to other manufacturers an I ended up purchasing one of their v90 cards. The card is so incredibly fast and I'm very confident in the safety of my data on this card. I have a Lexar card that's rated fast enough for me to shoot 4K video on it, but in reality it won't buffer fast enough and can't keep up with the camera, so I was forced to shoot in 1080p with that card. I've never been able to out shoot my prograde card, or seen it bog down or slow down in anyway. I'll be buying only prograde cards from now on.
