   I've performed a speed test of a Patriot XT 4 GB USB Flash Drive on three different computer systems and I've gotten widely varying results. All systems are running Windows XP Pro SP3. See below:

   System 1:
   Intel 6550 2.33 GHz CPU with 2 GB RAM: Read Speed is 31.0 MB/S, Write Speed is 10.43 MB/S

   System 2
   Intel Pentium 4, 2.8 GHz CPU with 2 GB RAM: Read Speed is 26.3 MB/S, Write Speed is 10.2 MB/S

   System 3:
   Intel Pentium 4, 1.6 GHz CPU with 512 MB RAM: Read Speed is 16.0 MB/S, Write Speed is 8.3 MB/S

   System 1 Note:
   System 1 is my newest machine having a Dual Core CPU and faster bus speeds, but processor speed is lower than that of system 2.

   System 3 Note:
   System 3 is an older computer that has a Rosewill USB 2.0 5-Port PCI Adapter installed to give it USB2 capability.

   I've not found anything on the web about USB 2.0 having minimum system requirements in order to achieve it's maximum performance; yet system performance seems to be a real factor.

   Byteboss, thank you for doing the research! This goes further to help explain why some people are getting such different overall results. Your data also reinforces the need for a simple usb speed tester built into eBoostr ... especially for those "non-technical" users who need a quick way to test different flash drives, and in different ports. And as a way to get maximum speed out of whatever hardware one is using.

   The data rates listed in the eBoostr control panel for each cache device is not enough of a direct measurement ... and I've seen those numbers change somewhat dramatically on the same drives and same cache configurations on the same machine.
