Memorex
Honestly, a Flash Drive that can withstand 2 years of High School use with stuff being constantly put on, being thrown around, being ripped out of computers without safely removing first by idiot friends and/or family AND does not run into any issues with transfering data between OS X and Windows is a great brand in my eyes.
Oh and avoid U3 flashdrives like the plague. It was a great idea that had a lot of promise, but in the end it just didn't work out.
