ADATA Premier Pro UHS-I U1 Class 10 32GB SDHC Memory Card Review

Rating: 9.0.

With the widespread emergence of the latest Secure Digital specification and the UHS speed class, ADATA has released some of the fastest SD memory cards on the market in the Premier Pro UHS-I U1 line-up. Can the theoretical performance prove its use in real world scenarios?

Based on the latest SDA 3.0 specification, the UHS-I, or Ultra-High Speed Phase 1, interface used on ADATA's Premier Pro memory cards gives them sequential speeds of up to 95 MB/s read and 45 MB/s write.

Available in capacities of 16 and 32GB, with a 64GB SDXC variant existing, ADATA is targeting professional photographers and enthusiasts that crave ultra-fast storage for their SD-compatible devices.

With sequential speeds comparable to those of many 2.5″ hard drives, can the ADATA Premier Pro UHS-I U1 32GB SDHC memory card translate numbers on a specification sheet into real world performance?
