ADATA Premier Pro 32GB UHS-1 microSDHC Review

CrystalDiskMark

CrystalDiskMark is a small HDD benchmark utility for your hard drive that enables you to rapidly measure sequential and random read/write speeds.

Here are some key features of “CrystalDiskMark”:

• Sequential reads/writes
• Random 4KB/512KB reads/writes
• Text copy
• Change dialog design
• internationalization (i18n)

Moving over to CrystalDiskMark we find that whilst the baseline performance is lower than expected, the real world performance is not affected any further. With speeds topping out at just under 38MB/s on the read side and just under 35MB/s on the write, the Premier Pro is still well over the 10MB/s minimum speed required for UHS-I classification.
