All cards occasionally turn up defective. Transcend might have a few more failures than the others, but its not really significant unless you are relying on it for making a living, in which case, you'd probably have a couple dozen cards.
Since its a SD card, do a low level format on it. That should map out any bad memory cells. If it fails again, toss it or ask Transcend to exchange it.
If you are formatting in camera, be sure to check the low level format option. If your camera does not have that option, do a complete (not quick) format in your computer.
