    Is it possible to use a storage disk (such as a USB drive) as RAM?

    Sometimes, due to issues with my laptop's RAM, the computer is very slow. As such, is there an option to use a pendrive as RAM on Windows 7?

    If you're using Windows (Vista or Seven, I think), you must insert your pendrive in a USB version 2.0 or higher port and windows will show the AutoPlay dialog. One of the options, usually the last, is "Speed up my System". Select it and you will be taken to the properties window of the pen, in the ReadyBoost tab. From there you can make your settings.

    Windows will refuse to ReadyBoost your pendrive if it doesn't meet the performance requirements!
    My guess is that it also requires the NTFS file system!

    There's no way to use it as physical RAM, but you can page to it, on Vista/7 this can be done with ReadyBoost, on XP you can just set it to do so in My Computer > Properties > Performance > Advanced > Virtual Memory. It should be mentioned that this is no replacement for physical RAM, though.

    You can set up Windows to use the USB flash disk as Virtual Memory.

    1. Connect your pen drive to your PC [pen drive should be at least 1 GB or if you having 4 GB then its better]

    2. Allow PC what he is supposed to do,let system to detect pen drive.

    3. Right click on the My Computer and select the properties

    4. Go to advanced and then performance setting then advanced

    5. Select pen drive and click on custom size " Check the value of space available "

    6. Enter the same in the Initial and the Max columns

    7. Now restart your pc and enjoy your fast and super system

    Creating Bootable Vista / Windows 7 USB Flash Drive

    This will walk through the steps to create a bootable USB flash drive for the purpose of installing a Vista or Windows 7 OS. These instructions assume that you have a computer with Windows Vista installed on it.


    • USB Flash Drive (4GB+)
    • Microsoft OS Disk (Vista / Windows 7)
    • A computer running Vista / Windows 7

    Format the Drive

    The steps here are to use the command line to format the disk properly using the diskpart utility. (Be warned: this will erase everything on your drive. Be careful.)

    • Plug in your USB Flash Drive
    • Open a command prompt as administrator (Right click on Start > All Programs > Accessories > Command Prompt and select “Run as administrator”
    • Find the drive number of your USB Drive by typing the following into the Command Prompt window:
      • diskpart
      • list disk
    • The number of your USB drive will listed. You’ll need this for the next step. I’ll assume that the USB flash drive is disk 1.
    • Format the drive by typing the next instructions into the same window. Replace the number “1” with the number of your disk below.
      • select disk 1
      • clean
      • create partition primary
      • select partition 1
      • active
      • format fs=NTFS
      • assign
      • exit
    • When that is done you’ll have a formatted USB flash drive ready to be made bootable.

    Make the Drive Bootable

    Next we’ll use the bootsect utility that comes on the Vista or Windows 7 disk to make the flash drive bootable. In the same command window that you were using in Step 1:

    • Insert your Windows Vista / 7 DVD into your drive.
    • Change directory to the DVD’s boot directory where bootsect lives:
      • d:
      • cd d:\boot
    • Use bootsect to set the USB as a bootable NTFS drive prepared for a Vista/7 image. I’m assuming that your USB flash drive has been labeled disk G:\ by the computer: bootsect /nt60 g:
    • You can now close the command prompt window, we’re done here.

    Copy the installation DVD to the USB drive

    The easiest way is to use Windows explorer to copy all of the files on your DVD on to the formatted flash drive. After you’ve copied all of the files the disk you are ready to go.

    Set your BIOS to boot from USB

    This is where you’re on your own since every computer is different. Most BIOS’s allow you to hit a key at boot and select a boot option.
