I bought a bunch of these for many many hours use with hi-res video cameras and every one has been fast and flawless.Plus, if you get more than one like me, you might want a way to keep track of which is which. Notice there is a small blank area in the red to the right of the SanDisk name. You can write a number there with a fine tip marker. Don't try that on one of those solid black chips!
