Windows Vista has a very cool feature called Readyboost which allowed you to use your Flash/Pen drives to boost your system performance. It allowed the use of Pen Drives as RAM in order to increase system performance. However, no such feature is available for Windows XP users.

eBoostr is an application that gives you the Readyboost feature in Windows XP. Using this application, you can use your Flash drives or hard drives as another layer of performance boosting cache for XP. You just need to plug in your Flash drives, select the amount of space to be used to speed up system performance. It gives the best results for frequently used applications such as office programs etc. It will be very useful for Laptop owners as RAM upgrade is quite costly for them. Some of its features are

• Smart caches frequently used applications and files for maximum performance speed up
• Supports both USB and non-USB removable media devices, as well as additional hard disks
• Allows up to 4 devices for simultaneous smart caching
• Cache file size of up to 4GB on each device

The free trial version gives you around four hours of functionality each time you boot up and full version is available for around $29.
