Have an older laptop that seems to be sooo...slow? This little trick can speed it up! Most people have a USB flash drive just lying around, maybe you bought a 2gb or 4gb back in the day and later upgraded to a higher capacity one. Need something to do with those extras rather just toss em in a drawer?
Windows 7 (and Vista) come with a feature called Readyboost. If your PC is running low on RAM, Readyboost will use the flash drive for its cache, rather than your hard drive.
Why do I care?
Your PC uses RAM to store programs and files that you use constantly. When your RAM runs out, it begins using your hard drive to temporarily store files for use, known as caching. The input/output of RAM is considerably faster than your hard drive. This is why when you are out/low on RAM, your computer begins chugging along at an insanely slow speed.
Readyboost, instead of using your hard drive, will use the USB flash drive for caching when you are out of RAM. USB I/O is faster than most hard drives on older PCs. This will increase your system performance, launching applications faster.
How do I use it?
To turn ReadyBoost on or off
Plug a flash drive or flash memory card into your computer.
In the Autoplay dialog box, under General options, click Speed up my system.
In the Properties dialog box, click the ReadyBoost tab, and then do one of the following:
To turn ReadyBoost off, click Do not use this device.
To use the maximum available space on the flash drive or memory card for ReadyBoost , click Dedicate this device to ReadyBoost. Windows will leave any files already stored on the device, but it'll use the rest to boost your system speed.
To use less than the maximum available space on the device for ReadyBoost , click Use this device, and then move the slider to choose the amount of available space on the device you want to use.
Should I use it?
Readyboost is mainly for older PCs with low amounts of RAM.
To know if Readyboost can help you:
Click the Start button.
Right click Computer.
Look under System and how much Installed Memory (RAM) there is in the PC. If the amount is 2.00GB or less, Readyboost will most likely benefit this PC. If you're around 4.00GB of installed RAM, it all depends on how many programs you use at once. If you are noticing slowness, there is no harm in trying.
