The SanDisk 32GB microSDHC Memory Card Ultra Class 10 UHS-I with microSD Adapter is a micro-size Secure Digital High Capacity memory card. With 32GB of data storage capacity, the card provides ample space for photos and videos captured with your camera or smartphone. It offers an SD Class 10 rating along with an Ultra High Speed Class 1 rating, for read speeds up to 30MB/s and lower write speeds that should at least be able to exceed the Class 10 minimum of 10MB/s. These speeds make the card ideal for capture and transfer of full HD 1080p video. A built-in write-protect switch found on the SD adapter prevents accidental data loss.
