This stick has no annoying software installed on it and one of the reviewers even put one through the washing machine and it still worked! Even cheaper if you buy more than 1.
This 8GB module has enough room to hold around: 2000 MP3's at 128 kbps, 5000 Jpeg's at 3 MegaPixels and 24 hours of Mpeg4 video!
Both the read and write speeds are very fast for a budget USB stick (most write at around 4-5MB/sec).
Read: 26MB/sec (173X)
Write: 7MB/sec (46X)
