Before anyone trashes this, if you want a CHEAP 8GB USB stick with CHEAP performance please look elsewhere.
This is an extremely HIGH peerformance USB Pen Drive which is available at a very good price. It offers speeds of +30Mb/s read and +20MB/s write. Random Access times are also very fast. Anyone that has used an ordinary USB stick knows how tiresome it is waiting for large files, or many small files to copy. This really does speed things up nicely. I will attach my own performance graph below.
The device itself is very durable. It is surrounded by rubber and I am sure you can bounce it of walls without damaging it.
This is the fastest performing device in it's price range. I know, I spent days trawling the web for reviews and stats.
