HD Tach showed that the IronKey had a burst speed of 31MB/sec., an average read rate of 29.6MB/sec. and a 6-millisecond random access rate. In other words, the IronKey is almost twice as fast as the F200. (The IronKey's CPU utilization rate was also, at 22%, vastly higher than any other drive we tested.)

When it comes to pricing, Imation's Defender F200 seems high, but you have to remember that you're paying for an extremely secure device.

The drive comes in capacities ranging from 1GB for a suggested retail price of $99 to 32GB for $349. As of this writing, it was only available to resellers, but it should be on the general market soon.
