There are lot of free tools available to speedup your computer and some of them we covered earlier in TechSmartlife. They all work by fine tuning your windows settings or cleaning junk files etc., I observed another interesting feature when playing around with my USB device on Windows 7 today. Low memory can make your computer sluggish because Windows, which needs a place to stash data, turns to the hard drive. Hard drive access is much slower than flash drives. The feature, called ReadyBoost in Windows 7 provides a simple way to speed up your PC, it is designed to use your flash device which is a speedier alternative to hard disk, when your PC’s RAM is running low.
Whenever you plug in a USB flash drive or card, an AutoPlay options dialog would be shown to you and mostly the last option would be the ReadyBoost. You can also invoke the ReadyBoost options window by right clicking on the removable media drive from the Window Explorer and selecting the Properties context menu.
ReadyBoost works with most flash storage devices. In Windows 7, it can handle more flash memory and even multiple devices—up to eight, for a maximum 256 gigabytes (GB) of additional memory. Microsoft recommends atleast 1GB free space in a flash device for ReadyBoost to effectively speed up your computer. Windows shows a message to cleanup your flash device whenever it finds not enough space. For best results, use a flash drive or flash memory card with at least double the amount of available space as the amount of memory (RAM) in your computer.
