## Long description

SanDisk microSD Express delivers next-level speed and performance for creators and explorers who need fast file transfers and high-quality capture. With a PCIe Gen 3‑NVMe interface and compatibility with microSD UHS‑I and UHS‑II devices, this card supports up to 5.3K video and 10MP RAW image capture while offering transfer speeds up to 880 MB/s when paired with compatible readers.
Advantages
The card provides exponentially faster read speeds—up to 4.4× faster than SanDisk’s fastest microSD UHS‑I cards—enabling rapid offloads and shorter wait times. It supports faster burst and sustained recording speeds comparable to SD UHS‑II cards, and its ThermAdapt enclosure and adaptive thermal controller help prevent device overheating. The card is highly durable and resistant to water, temperature extremes, humidity, drops, shocks, magnets, x‑rays, and wear. A lifetime limited warranty and an optional two‑year RescuePRO Deluxe file recovery service add data protection and recovery options.

How to use
Insert the SanDisk microSD Express card into a compatible device or into a SanDisk PRO‑READER SD Express Dual Card or another compatible reader to achieve maximum transfer speeds. For routine capture, use the card in cameras and devices that support microSD UHS‑I or UHS‑II; when paired with a PCIe‑NVMe‑capable reader you can offload large files quickly. Monitor device temperature during extended recording sessions; ThermAdapt helps manage heat but adequate airflow is recommended for sustained high‑performance use.
Recommendations
Use a compatible SanDisk PRO‑READER SD Express Dual Card (sold separately) or other PCIe‑NVMe reader to maximize transfer speeds. Keep backups of important content and consider activating the two‑year RescuePRO Deluxe service for added file recovery protection. Verify device compatibility before purchasing to ensure full performance benefits.
