If you have Vista system, just plug a flash drive that is ReadyBoost compatible into USB port and Vista will ask if you want to use this drive as ReadyBoost. Accept what is suggested by Vista and you are ready to go. It is realy speeding up your computer.
By using ReadyBoost
ReadyBoost
To use ReadyBoost a person obtains a flash drive and places the flash drive in the USB port on the computer. ReadyBoost allows your computer to store memory on it to speed up the computer.
No, Depending on what processor you have and how much ram you have can depend how fast your computer is. also a hard drive RPM speed as well.Edit: Windows 7 has a feature called ReadyBoost that can increase your RAM by using a USB Flash drive. It only works if your computer would benefit from its use (e.g. you are using a lot of virtual memory, and your hard drive is slower than the USB port). When ReadyBoost is operational, it will increase the speed of your computer by reducing hard drive virtual memory swapping. So the answer is actually "maybe."
4GB, minimum size is 256mb.
It all depends on how much RAM (Random Access Memory) you have. Windows 7 runs smooth with at least 2GB (Giga Bytes) of RAM. I personally have a small laptop with Windows 7 which only has 1GB of RAM and it still runs fine. But if you want your computer to have more RAM on Windows 7, simply insert an external flash drive into your computer that at least has 1GB available. After you insert it, a message on your computer will pop up asking you what you would like to do with the flash drive. One option says "Speed Up My System Using ReadyBoost". Click on that and another box should pop up. Click on the button that says "Dedicate this device to ReadyBoost" and click "Apply". As long as you have the flash drive in, you should have more RAM. I personally have an 8GB flash drive which I use with ReadyBoost and my laptop runs really fast!
False
If you've got Windows 7 or Vista, open the properties of the drive, go to the Readyboost tab and change the settings. If you've got XP and some git has done it to your drive and then given it back to you, you're stuck. If you can't get access to a Win 7 or Vista machine to fix it, try a Linux live CD
Neither technology is available for XP, however ReadyBoost-like functionality can be achieved by moving your paging file to a flash drive.
Not possible sd card is just a disk to store files on, it is not assigned to the operating system. Windows ReadyBoost With Windows ReadyBoost, you can use a flash memory device, like a universal serial bus (USB) flash drive or secure digital (SD) memory card, to improve your computer's system performance without having to add additional memory. The flash memory device serves as an additional memory cache-memory that the computer can access much more quickly than it can access data on the hard disk drive.
