I'm looking to buy some usb sticks which will mainly be used in tech support for the purposes of removing viruses and booting up various OS's. Therefore, I am looking for the following features:
Write protected switch (so that they may be safely plugged in to potentially infected machines)
As fast as possible (so that loading, for example, a windows recovery, doesn't take forever)
At least 4GB in size
Any other features that might be useful for the above purpose
Price is no object but, of course, the cheaper the better.
