Access Time Results
Access time is typically not a very interesting metric. However, Kingston’s new 128 GB USB 2.0 Data Traveler 200 takes the longest average time to physically access data (as we'd expect in a comparison of this sort). The three eSATA-powered thumb drives are quicker, and deliver their best access times in eSATA mode.
Write access takes much more time and reveals the weakness of multi-level cell (MLC) flash memory, which is used by all of these devices.
