Many of today’s digital cameras offer dual card slots, increasingly a 2-slot combination of CFExpress Type B or A + SDXC. Some are still dual SDXC, but the same ideas apply.
I’m a professional photographer by trade. In the video below, I discuss how to effectively use dual card slots in digital cameras, particularly for minimizing the risk of image loss from accident/theft/etc, and why I do what I do when traveling for weeks at a time.
- Dual slots offer redundancy in case one card has an issue.
- High capacity cards mean no fumbling to swap out a full card, and thus, no risk of losing that card down a crack in the rocks or creek.
- A large-capacity secondary card allows for weeks-long shooting on extended trips.
- Theft of computer and/or backups from vehicle are backstopped by using high-capacity cards and not erasing until home and all is backed-up.
Professionals should be using pro-grade cards
Over the years, I’ve had too many well-known brand-name cards fail (corrupt images) or literally come apart at the seams. I now use OWC Atlas camera cards exclusively with impeccable reliability and speed, as well as a de facto factory-fresh reset via OWC Innergize.
My choice of cards for my work are the OWC Atlas Ultra and OWC Atlas Pro line, using the hyper-fast Atlas Ultra as the main/primary store (CFExpress Type B preferred), and a higher-capacity Atlas Pro SDXC as the backup card.
