Factors to Consider
Frequently Asked Questions
Can I use the same card for photo and video on a wedding day?
Yes, if the card is rated V90 and you're not switching between high-bitrate video and rapid burst photography every 30 seconds. The real constraint is buffer clearing—swap cards every 20–30 minutes of mixed shooting to avoid buffer hangups during critical moments. I prefer dedicated cards: one fast V90 for video B-roll, one for stills. It's a small safety margin that costs nothing.
Do I really need CFexpress Type B, or is UHS-II SD enough?
UHS-II SD cards max out around 250 MB/s write; CFexpress Type B handles 1400+ MB/s and handles thermal load better. If your camera has CFexpress slots (Sony a1, Canon R5, Nikon Z9), use them—you'll see fewer buffer stalls and heat throttling in sustained shooting. If you're on a DSLR or a body with only SD slots, high-end UHS-II V90 cards (SanDisk Extreme PRO, Lexar Professional) are perfectly adequate for weddings.
What's the difference between MLC, TLC, and QLC NAND, and does it matter for wedding work?
MLC stores 2 bits per cell (older, expensive, very durable), TLC stores 3 bits per cell (standard now, balanced durability/cost), QLC stores 4 bits per cell (cheap, lower lifespan, slower under stress). For wedding photography, TLC cards from reputable brands are the sweet spot—they handle thousands of write cycles and maintain speed under heat. Avoid QLC for critical work; you're paying a few dollars less for noticeably worse thermal performance and lower cycle life.
Should I format cards in-camera or on a computer?
Always format in-camera, right before the shoot. In-camera formatting optimizes the card's file system to match your camera's codec and sector alignment, which reduces corruption risk and ensures the camera can write at peak speed. Formatting on a computer leaves the card's old structure intact, which can cause buffer issues or slow writes mid-shooting. I format every card in-camera 15 minutes before doors open—it's a three-second ritual that matters.
How many cards should I actually bring to a wedding?
Minimum: three cards per body (two active, one backup). For a full-day wedding with two bodies, I carry six cards total—two assigned to each camera, plus two spares formatted and ready in my bag. One card fails or gets corrupted, I'm still shooting. If you're bringing one body and conservative capacity (128GB), you'll swap or offload every 3–4 hours; factor backup time into your logistics.
Can I use a memory card reader, or should I shoot directly to external SSD?
A fast USB 3.1 card reader (SanDisk, ProGrade) is your standard workflow—offload to a laptop or portable SSD during breaks or after the ceremony. Direct-to-SSD shooting via USB-C is possible on newer cameras but drains battery fast and adds tether complexity mid-event. Stick with cards + reader during the shoot, offload to redundant storage (two external drives, minimum) the same evening. Cards are your on-set safety net; SSDs are your backup.
Do expensive cards really last longer, or is that marketing?
Expensive pro-grade cards (ProGrade, SanDisk Extreme PRO) use better NAND binning, better firmware, and better thermal design, which translates to longer lifespan and fewer field failures—not marketing fluff. Budget cards fail faster, especially after thermal stress or high cycle counts. I've seen cheap cards drop to half their rated speed after a single hot day; pro cards hold 90%+ speed over years. The premium buys reliability and resale value, not just a brand name.
Conclusion
Summer wedding photography demands cards that don't quit under heat, write fast enough to clear buffers without hesitation, and won't corrupt when you're hours from a backup. CFexpress Type B dominates if your camera supports it; high-end UHS-II V90 cards are the reliable choice for DSLRs and older systems. Buy from established manufacturers (SanDisk, ProGrade, Lexar, Sony), carry redundancy (at least three cards per body), and format in-camera before every shoot.
The card itself is invisible when it works and catastrophic when it fails. Spend the extra $30–50 per card, bring backup, and focus on the light.
