Have fitted USB2 card but throughput speed very slow....seems less than USB1
speed!
XP Devise Manager shows Standard Enhanced PCI to USB host controller and
driver as Microsoft driver and date 01/06/02...is that the latest?
If not where can I download the latest drivers? Thanks. John

Bit further forward...question raised because new flash pen drive showed as
crawling assumed it was the USB card but when comparing with another flash
pen drive now realise its the damned pen that's outputting speeds less than
USB1 !....perhaps my fault for buying it cheap from Hongkong (but made in
China)!
Anyone know if that's it or is it possible to somehow "upgrade" such a flash
pen drive from slow to USB2 speeds?
And also anyone know if flash pens are supposed to function at the same
speed when transfering data TO and FROM the pen?
Thanks J
 
Flash Memory based devices have relatively fast Access times, but
their overall throughput isn't that great.
For example my LG 1-Gigabyte performs at:
Access time of 1.0 mS
Burst Speed of 10.0 mbps
Average speed of 8400 kBytes/s
 
Mine = between 1.0 and 0.5MBps!
