✍️ Why I Wrote This

On a trip to Rio a couple years back I was shooting 4K video of the beach and street parades on a cheap SD card, and of course it filled up mid-shoot on the one afternoon I actually wanted the footage. Worse, part of what I did manage to save turned out corrupted when I got home, which is its own special kind of gut punch after a trip like that. I compared notes with a videographer friend about professional-grade cards versus the standard ones I'd always grabbed off a shelf, and switching to a proper high-speed card has meant zero corrupted clips on every trip since.

Frequently Asked Questions

Will this work in my camera's SD card slot?

No, this is a CFexpress Type A card, so it only works in cameras with that specific slot — check your camera's manual before buying.

Is it fast enough for 4K video without dropped frames?

Yes, the sustained write speeds are built for demanding 4K and 8K workflows without the frame drops cheaper cards sometimes have.

Does it come with a card reader?

No, a reader isn't included, so factor that into your budget if you don't already have a compatible one.

Is the price worth it over a standard SD card?

For professional or high-bitrate video work it's a noticeable upgrade in reliability, which is the main reason it comes up in r/deals threads about pro camera gear despite the higher price.
