SanDisk Memory Card Types & Formats

SanDisk memory cards deliver the speed and reliability your camera setup demands. Whether you're capturing fast-paced action, shooting cinema-quality 4K video, or archiving thousands of photos, SanDisk offers storage solutions built for every format and use case. At Samy's Camera, we stock a complete range of SanDisk cards across CFexpress Type B, SDXC, microSDXC, and CFast 2.0 formats to match your specific workflow.

SanDisk manufactures memory cards across multiple standards to support the widest range of devices and workflows. Understanding which format your equipment uses is the first step toward choosing the right card. Each format excels in specific applications, from professional cinema work to compact travel systems.

CFexpress Type B Cards

CFexpress Type B represents the fastest standard for modern professional cameras and cinema equipment. These cards feature read speeds that reach 1700 MB/s and write speeds up to 1200 MB/s, enabling sustained 4K and 6K video capture with zero frame drops. The format uses a smaller physical footprint than older XQD cards while delivering significantly faster performance, making them ideal for fast-action photography and high-bitrate video work. Available in capacities from 64GB to 512GB, these cards support high-bitrate 4K 60fps and 8K workflows with professional-grade durability for demanding environments.

SDXC Memory Cards (UHS-II)

SDXC cards represent the universal standard for digital cameras worldwide. SanDisk's Extreme PRO UHS-II SDXC cards deliver read speeds up to 260 MB/s and write speeds up to 240 MB/s, providing rock-solid performance for burst photography and 4K capture on DSLRs and mirrorless systems. UHS-II cards work in any camera with an SD card slot, making them exceptionally versatile. Available from 32GB to 1TB capacity, they support V60 and V90 ratings for professional video work while maintaining backward compatibility with UHS-I and older SD devices.

microSDXC Cards

When size matters, SanDisk microSDXC cards pack full-size performance into a footprint smaller than a postage stamp. These cards excel in action cameras, drones, smartphones, and portable recording devices. Despite their compact size, they deliver read speeds of up to 190 MB/s, suitable for 4K capture on compatible devices. Each card includes an SD adapter for use in standard SD card slots. Sizes range from 32GB to 256GB, making them ideal for GoPro, DJI drones, and action cameras with extreme durability ratings and drop-proof construction.

CFast 2.0 Cards

CFast 2.0 represents the professional standard for cinema-grade workflows, using a compact form factor with enterprise-class performance reaching write speeds of 150 MB/s. CFast 2.0 excels in high-speed cinema work where sustained, uninterrupted write performance is non-negotiable. With VPG 130 ratings that guarantee minimum write speed, these cards ensure reliable 4K and cinema capture without bottlenecks. Available up to 512GB capacity, they deliver the sustained write performance necessary for high-bitrate capture across any cinema camera platform.

Specifications & Performance

Speed ratings matter enormously when you're capturing critical moments. SanDisk publishes transparent specifications: read speeds range from 160 MB/s (SDXC standard) to 1700 MB/s (CFexpress Type B), while write speeds span from 90 MB/s to 1200 MB/s. Video speed classes V30, V60, and V90 guarantee minimum write speeds for different video applications. Storage capacities range from 32GB to 1TB depending on format, with operating temperatures typically 0-60 degrees Celsius and storage temperatures from minus 40 to 85 degrees Celsius.

Who Uses SanDisk Memory Cards

Professional Photographers

Professional photographers trust SDXC cards for critical assignments. Whether shooting weddings, editorial work, or commercial campaigns, rapid burst rates and consistent write speeds mean every frame gets captured. The extensive capacity range lets photographers work extended sessions without swapping cards, reducing downtime between jobs.

Video & Cinema Professionals

Cinema and broadcast workflows demand cards that never drop frames. SanDisk CFexpress Type B and CFast 2.0 options handle sustained 4K and 6K capture with zero compromise. Filmmakers working with digital cinema cameras rely on these cards' proven track record for delivering complete, uninterrupted material to post-production teams.

Action Sports & Travel Photographers

Compact, durable solutions define travel and adventure photography. SanDisk microSDXC cards paired with GoPro accessories and drones capture extreme conditions without flinching. Drop-proof, temperature-resistant construction handles everything from arctic expeditions to desert heat with the compact format providing backup capacity without bulk.

Mirrorless & DSLSR Shooters

Canon, Nikon, Sony, and Fujifilm users benefit from SanDisk's card lineup optimized for digital mirrorless cameras. Fast burst support accommodates continuous shooting at 10+ frames per second, while large capacities maximize shot count before downloading. Reliable performance means more focus on composition and less concern about technical failures.

Choosing the Right Card for Your Workflow

For fast-action photography, CFexpress Type B delivers the fastest write speeds for 10+ frames per second without buffering. For 4K video work, either CFexpress Type B or SDXC UHS-II cards work depending on your camera system, though both support sustained 4K recording without frame drops. For travel and backup, microSDXC cards maximize capacity in minimal space, storing thousands of photos on cards no larger than a fingernail. For professional cinema, CFast 2.0 cards with VPG 130 rating ensure workflows never compromise.

Frequently Asked Questions

What's the difference between CFexpress and SDXC?

CFexpress Type B is the newest standard with the fastest speeds (up to 1700 MB/s read). SDXC is the universal SD standard that works with any camera featuring an SD card slot. CFexpress suits professional cinema and high-speed action work. SDXC suits photographers using standard cameras and hybrid workflows. Both support 4K, but CFexpress provides headroom for multi-camera cinema setups.

Do I need a V90 rated card for 4K video?

Not always. Many 4K cameras require a minimum V60 rated card (90 MB/s sustained write). Higher bitrate work like cinema or 6K capture benefits from V90 cards (300 MB/s sustained write). Check your camera's manual for the exact requirement to avoid frame drops.

Can I use a microSDXC card in my camera's SD slot?

Yes, when using the included SD adapter. The microSDXC card slides into the adapter, which then inserts into your SD slot. Performance remains the same. The adapter simply enables use in standard SD readers. Remove the card carefully when finished to avoid damaging it.

What's the difference between writing and reading speeds?

Write speed determines how fast the card saves images as you shoot. Read speed determines how quickly the camera retrieves images from the card for playback or transfer to your computer. Write speed matters most for active photography. Both matter when transferring files to edit.

How do I know if my card is compatible with my camera?

Check your camera's manual for the card format it accepts. It will specify SD, CFexpress, CFast, or microSD. Buy the matching format. If your camera accepts UHS-II SDXC cards, any SanDisk Extreme PRO SDXC works. The format determines compatibility, not the brand.

Are SanDisk cards fast enough for 8K video?

SanDisk CFexpress Type B cards support 8K workflows on compatible cinema cameras, with speeds exceeding 1200 MB/s write. This handles the sustained data demands of 8K capture. Standard SDXC cards may struggle with 8K on some cameras. Always verify your equipment's specs before purchasing.
