SanDisk Memory Cards

SD, microSD, CFexpress, and CompactFlash Cards for Every Camera and Device

SanDisk and Western Digital memory cards cover every removable flash storage format: SD, microSD, CFexpress Type B, and CompactFlash, rated for professional photography, 4K and 8K video production, action cameras, drones, and 24/7 surveillance recording. The lineup sits within the broader Western Digital family of hard drives, SSDs, and flash drives, and you can compare across all portable storage in the complete storage category.

SanDisk Memory Cards for Every Use Case

• Professional photography and videography — Extreme PRO SDXC and CFexpress Type B cards in 128GB to 512GB deliver the sustained write speeds needed for high-resolution raw burst shooting and 8K video capture in professional camera bodies
• Action cameras and drones — Extreme microSD cards with V30, UHS-I, and U3 ratings support 4K UHD recording in GoPro, DJI, and Insta360 devices with rugged construction that withstands drops, water, and temperature extremes
• Dash cameras and continuous recording — High Endurance microSD cards rated for up to 20,000 hours and MAX Endurance cards rated for 30,000 hours handle the constant write-and-overwrite cycles that standard memory cards cannot sustain
• IP camera and surveillance edge storage — WD Purple microSD cards from 64GB to 1TB are engineered for 24/7 continuous recording in indoor and outdoor security cameras with temperature extremes and constant write operations
• Everyday devices and smartphones — Ultra microSD and SDXC cards from 16GB to 512GB provide reliable UHS-I storage for Android phones, tablets, and consumer cameras at everyday prices

Choosing the Right SanDisk Memory Card

SanDisk organizes its memory card lineup by speed class, form factor, and endurance rating. Extreme PRO cards deliver the highest speeds for professional cameras. Extreme cards balance speed and ruggedness for action cameras and drones. Ultra cards cover everyday consumer use. High Endurance and MAX Endurance cards are built specifically for continuous-recording devices. WD Purple cards target 24/7 surveillance. Matching the card to your device's requirements prevents dropped frames, corrupted footage, and premature card failure.

Speed Classes and Ratings

Memory card speed ratings determine minimum sustained write performance. UHS-I is the baseline bus interface found in most consumer devices. V30 (Video Speed Class 30) guarantees 30 MB/s minimum sustained writes for 4K video. V60 and V90 push to 60 and 90 MB/s for 6K and 8K recording. CFexpress Type B cards use the PCIe interface for professional camera bodies that demand the highest throughput for raw burst shooting and cinema-grade video.

Endurance for Continuous Recording

Standard memory cards are designed for intermittent read/write cycles and wear out quickly under 24/7 use. The SanDisk High Endurance line is rated for up to 20,000 hours of Full HD recording, and the MAX Endurance pushes to 30,000 hours, using more durable NAND and specialized flash management. WD Purple microSD cards are engineered specifically for IP camera edge storage with endurance ratings that match or exceed the High Endurance line.
