Here’s my H2testw report for the SanDisk Ultra microSDHDC UHS-I 16GB which is a Class 10/UHS-I class micro SD card. The report was run on a Windows 8.1 laptop with a Samsung SSD 840 PRO Series hard disk using the provided micro SD to SD adapter with H2testw 1.4 configured to write and verify the entire contents of the drive.
Here is the H2testw report in plain-text.
