Thanks OP, but class 4? Ouch....that means 4mbps write speed, compared to class 10 which is 10 mbps

Apparently Class 4 through Class 10 all have relatively similar actual throughput rates:,2940-12.html

You don't really see much of a gain until upgrading to UHS.

It's a good price for what I'm using them for, which is Sony PSPs.

it's not all about sequential write speed. When used in Android phones or tablets, IOPs or small block writes are more important. Hafta see CrystalDiskMark benchmarks to know for certain.
