Verdict
When someone goes looking for a flash drive like the PNY IronKey 4GB flash drive they are looking for data security rather than pure performance. The PNY IronKey 4GB flash drive certainly lives up to the data security requirements with great ease of use. The data speeds are far from the fastest I have measured, but the drive is certainly livable on a daily basis and you don’t have to worry about data theft.
