Excellent Durability
These memory cards employ Error-Code Correction (ECC), and are extremely cold-resistant, heat-resistant and impervious to x-rays, making them one of the world's most rugged memory cards.
Increased speed, no increase in cost
Premier microSDHC/SDXC UHS-I Class 10 U1 memory cards have higher capacity, but without a higher price, and provide consumers with the faster read speeds of UHS-I specification at the price of a Class 10 card. Sequential reads are up to 80 MB/second, and write speeds reach the UHS-I speed class 1 specification. They are remarkably suitable for users who enjoy high definition photography and video recording. Running multiple applications simultaneously causes no loss in read/write speed.
