Storage always fills up faster than expected. Games grow larger, video files push higher resolutions, and phones or handhelds run out of room just when you need them most. A regular microSD card keeps working in those situations, yet the time spent waiting for transfers and loads starts to add up. SanDisk’s 256GB microSD Express card, priced at $58.99 (was $74), changes that equation with speeds that feel closer to a basic portable SSD than a traditional memory card.
That means it can read at up to 880MB/s and write at 650MB/s, which is impressive given that its sustained write performance never drops below 210MB/s. These values outperform most UHS-I cards, which have a maximum read speed of roughly 100MB/s. When connected with the appropriate reader, SanDisk estimates the speed increase is approximately 4.4 times faster than that of their fastest previous UHS-I microSD cards. With that much power, the SanDisk PRO-READER can transfer a 2-hour HD movie to your device in less than 3.5 seconds, and 60 minutes of 4K video shot at 30 frames per second is handled significantly faster than prior cards.
- NEXT GEN GAMING: Works with Nintendo Switch 2.
- READY FOR TOMORROW. Ready for future products with a PCIe-NVMe interface; performs at UHS-I speeds with microSD UHS-I and UHS-II devices.
- EXPONENTIALLY FASTER PERFORMANCE. Up to 4.4 times faster transfer speeds than our fastest microSD UHS-I cards [9]. Transfer a 2-hour HD movie in less...
All of this speed translates into faster game installs, level loads, and fewer missed frames during high-bitrate video recording. Even burst mode RAW shooting benefits from faster transfer times since it allows your device to keep up in real time. The capacity and speed also make file management much easier, since you’ll spend less time waiting for transfers to complete and more time doing what actually matters.
This card really shines in terms of compatibility, as it operates at full speed in microSD Express slots as well as older UHS-I and UHS-II devices (albeit it only runs at typical UHS-I speeds). So, even if you’re using an older phone, action camera, or handheld, you’ll be able to complete the task, but not as quickly. Games consoles like the Nintendo Switch 2 rely on microSD Express cards for game storage, so this model is ideal. To protect things from becoming too hot, SanDisk has integrated its ThermAdapt technology, which manages heat during persistent transfers.
When it comes to durability, SanDisk has thought of almost everything: the card is waterproof, can withstand extreme temperatures, and is resistant to dampness and magnets. In addition, it includes a lifetime limited warranty. SanDisk also provides RescuePRO Deluxe recovery software for two years, in case you need to recover any data.
