Choose from top-rated microSD™ cards to boost the storage on your devices with UHS-I/U1 and Class 10 ratings. When looking for a new card, consider factors such as gigabyte storage, compatibility among devices and transfer speeds. Other important aspects include video recording capability and durability.

Ample Storage Space Handles More Content

Amp up your storage space on phones, tablets and other devices with SD cards that expand your memory. The top-rated memory cards have storage capabilities extending from a 32GB memory to one that has 512GB of storage space. That gives you the ability to store hours of video and thousands of songs or photos on a single card without worrying about running low on space.

Multi-Device Compatibility Provides Extensive Use

Micro flash cards are a flexible storage option that work with a range of devices, including digital cameras, drones, phones and gaming systems to free up internal storage on those devices. Some microSD cards have a specific purpose, such as working solely with dash cams or video game systems. A memory card with adapter enables you to boost your storage for equipment that needs full-size SD cards, such as DSLRs.

Top-Rated Cards Are Durable to Withstand Harsh Conditions

Durability and protection are key components in many top-rated micro flash cards. The cards protect against shocks, static electricity, water damage and X-ray technology, so data remains intact after trauma. These cards are also resistant to extreme temperatures as low as -25 degrees Celsius and as high as 85 degrees Celsius.

Top-Rated Cards Help Apps Run Faster for Efficiency

The top-rated microSD cards have A1 and A2 app classifications to boost performance on smartphones and tablets. These cards help you run current apps faster and install new ones without download delays. They can also help free up internal storage space to improve the cache and functionality of other systems on your devices. The quick write speeds of top-rated cards enable you to capture photos and videos at up to 90MBps. Use card readers to quickly transfer data onto your computer at high speeds. Read speeds can reach up to 100MBps to improve the rate of transfer for your content.

Micro SD Cards Are Useful for Different Projects

Many USB flash drives and memory cards provide additional storage for a variety of content, including photos and videos. Use microSD cards to play video games and enjoy extra storage to expand your game library and save your data. Use a memory card to keep your dash cam’s footage rolling at all times, or get aerial footage with a drone.

V10 and V30 Classifications Record HD Videos

Have the space you need to shoot videos with external storage on SD cards. Use a memory card with adapter to utilize more video equipment that usually requires regular SD cards, such as a camcorder. Many top-rated cards offer video speeds from V10 to V30, so you can record at least 10MB of captivating full HD video footage every second.

"Used with a full frame Canon DSLR at 24 Megapixels in RAW format with a JPEG thumbnail. No problems with writing, but I'm not doing any burst shots or 4K recording. Never had a SanDisk card fail on me. Have a few R-Data cards that have held up over the years also, but SanDisk is my go to."
