Here are some guidelines to improve Pocket ACE performance.
Solution
Use a device with the following speed ratings and driver-support specifications:
USB 2.0 driver support
USB 2 high-speed certification (USB 1.1 and USB 2.0 "full speed" devices do not meet this criterion.)
Flash-device speed of minimum 60X or 10 megabyte/second
Store user data locally. If your home directory is on a network, performance will be degraded. Testing shows significant performance improvements using the shut down (not suspend) option when powering off a Pocket ACE.
