The JetFlash 600 here offers the best performance at an average price. He's not the cheapest stick, but one also gets power. In the Test Stick with me reached top speeds of 27 MB / s !!!, but only in the first few seconds of transmission, that's why I'm here from a Windows miscalculation :-)
The average transfer rate moves with me 15 to 17 MB / s. Absolutely satisfactory.
CONCLUSION:
Not cheap, but fast! Processing, however, is below average!
