REFRESH PRO ENABLED

To ensure your CFexpress Gold Memory Card performs at a maximum level for uninterrupted high-speed photography and video capture, your card needs to be Refresh Pro enabled.

WHAT OTHERS SAY ABOUT US
ETHAN R.

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.
