Tool to test a micro-SD card? Something free & simple

[RaiderJ]

Is there some simple software out there that I can use to test my micro-SD card? Looking to get an approximate idea of the read/write performance to see if I really did get a Class 6 card.

Many disk benchmarking programs can do the same with flash drives. HDTune and CrystalDiskMark come to mind. Though the speed is also dependent on the quality of the reader.

CrystalDiskMark works great - thanks!
