Why prograde digital?


ProGrade Digital understands the performance, quality, and reliability that professionals need to keep their businesses successful. Not only are photographers’ livelihoods and reputations dependent upon how reliable a memory card or workflow reader is, but so is their clients’ trust.


The comprehensive card testing all of our cards undergo prior to leaving the factory is far more time-consuming and rigorous than the testing processes used by other card manufacturers. We strive for the lowest possible field failure rate and achieve it after hours of testing. When you choose ProGrade Digital, you will have the highest-level of assurance that your card will perform flawlessly.


With years of experience working closely with professional DSLR and video camera manufacturers, our cards meet rigorous compatibility and qualification tests. Not only do our cards meet the quality compliance requirements from the manufacturer, but they’re also verified to operate with specific camera models.


We strongly believe that our customers come first, so if at any point in your card ownership you have issues, we will be there to take care of you. Our customer support is second-to-none and we look forward to introducing you to it.

Refresh Pro Enabled

For maximum performance of memory cards with uninterrupted high-speed photography and video capture, choose our Refresh Pro Software. All of our memory cards are Refresh Pro enabled meaning they perform two key functions: 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 SDXC V90 questions:

What is the SDXC Card?

The SDXC memory card allows you to do more with your device. Whether you’re looking for camera, video, or action-cam compatibility, the faster bus speeds enable improvements like professional-level recording. The speed improvements also exponentially increase the number of frames shot per second with SDXC cameras.

What is UHS-I vs UHS-II?

UHS (Ultra High Speed) defines bus-interface speeds up to 624 Megabytes per second with UHS-I (104MB/s), UHS-II (324MB/s), and UHS-III (624MB/s) classification for greater SDHC and SDXC device and memory card performance. As far as physical differences between the cards, UHS-I cards have one row of pins on the back of the card and UHS-II cards have two rows. ProGrade Digital only manufactures UHS-II cards.

What is the difference in SDHC vs SDXC?

The SDHC memory card standard is for capacities from 2GB up to 32GB, SDXC memory cards on the other hand have a capacity from 32GB to 2TB.

What is the difference between SDXC V60 and SDXC V90?

The Video Speed Class for SD cards is designated by a V followed by a number like V60 or V90. This designation replaces the C and U designations previously found on SD cards. Video Speed Class identifies the speed needed for 4K and 8K video capture which was not covered in prior designations. By covering a wide range of capture formats, video speed class is intended to simplify what consumers need to know about the speed of an SD card. A V60 card is tested to have a minimum sustained write speed of at least 60MB/s, while a V90 card has a minimum sustained write speed of at least 90MB/s.

I’ve heard a lot about the speed of memory cards but it’s confusing. What do i need to know about it?

Memory card speeds are important to the overall performance of your camera. Here are three things you should consider: Transfer speed: how quickly data (images or video) can be downloaded from the card. Faster transfer speeds require less time to import photos or ingest video to your computer. Write speed: how well a card performs in a camera. Most camera manufacturers do not disclose an exact specification. Instead, they simply specify the speed class rating that the camera requires. Speed class: professional-level cameras typically require the newer Ultra High Speed (UHS or UHS-II) categories described as U1 (10MB per second) or U3 (30MB per second). It’s best to match the speed of the memory card to the requirements of the camera.

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.
