Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

Is there a utility, for Windows 7 64-bit preferably, that can tell me the type of SD card or microSD card that has been inserted Class 4, class 6, etc.

Freeware is preferred, but I am willing to hear about other options.

You can use this utility (H2testw) to determine the class of your SD card. If the test result is "n MB/secs", then its class is "n".

Normally, SD cards are Class 2 unless it is specified on it.
