Download Readyboost Windows 7 64 Bit

Unlike Windows Vista, Windows 7 recognizes that ReadyBoost will not provide a performance gain when the primary disk is an SSD. Windows 7 disables ReadyBoost when reading from an SSD drive. External storage must meet the following requirements: Capacity of at least 256 MB, with at least 64 kilobytes (KB) of free space.

Cards with a capacity of one or two GB are indeed quite enough for ReadyBoost. Note: The following instructions and tips relate to Windows 7, but can also be used in a similar way for Windows Vista.

I have a NetBook or an older PC with relatively low memory or little disk space capacity. How can I use USB stick or an SD-card to improve the working speed?


Like its predecessor Windows Vista, Windows 7 provides the Windows ReadyBoost function to provide Netbooks or older PC systems with more memory. You can use non-volatile flash memory such as current USB memory stick or SD memory cards to improve the performance of your system. This additional memory is provided as cache memory, to speed up, for example, the loading or editing of large files.
Important: You need a USB flash drive or a memory card with a free storage capacity of at least 500 MB and a high data transfer rate. Since you can permanently 'park' SD cards in the designated PC slot, the small disks for ReadyBoost are particularly well suited. Cards with a capacity of one or two GB are indeed quite enough for ReadyBoost.
Note: The following instructions and tips relate to Windows 7, but can also be used in a similar way for Windows Vista.
Using ReadyBoost
1. Plug the USB stick or SD card into a free slot. The storage medium is detected immediately. In the dialog box Automatic playback click on the option Speed up my system.
2. If the dialog box Automatic playback does not automatically appear, open Windows Explorer by pressing [Windows button] + [E]. Then with the right mouse button click on the new drive in the left directory tree, and select the command Open AutoPlay.
3. Windows immediately determines, whether the storage medium is suitable for ReadyBoost. If this is not the case, you will receive a corresponding note. If your storage device is ready for ReadyBoost, click on the tab ReadyBoost on the option Use this device.
4. Windows proposes to use the free space for the memory optimization. If you follow this, you can then save no further data on the media.
For a PC-RAM of 2 GB it is sufficient if you reserve 2 GB memory for ReadyBoost. In this case, move the slider under Space to reserve for system speed to the right place – in this example: 2000 MB. You can also set this value by using the arrow next to the selection box.
5. Click on OK. The changes are immediately reflected on the external media.
6. In the drive view for the storage medium you see the reserved space now as file entry called: ReadyBoost.sfcache.
Deactivating ReadyBoost
1. Open the File Explorer by pressing [Windows button] + [E]. Then, you click on the ReadyBoost drive in the left side tree, so that in the right pane the file entry ReadyBoost.sfcache displays.
2. Click the file ReadyBoost.sfcache with the right mouse button and select the command Properties in the shortcut menu.
3. In the dialog box Properties click on the tab ReadyBoost.
4. Select the option Do not use this device.
5. Click on OK. The reserved space is immediately freed.

From a PowerPoint presented at the Windows 7 SIG on September 11, 2010.

What is ReadyBoost?

  • ReadyBoost can speed up your computer by using storage space on most USB Flash Drives and Flash Memory Cards.
  • The PC can get to data in RAM (memory) hundreds of times faster than it can fetch it from the hard disk.
  • That’s why your PC uses a cache, defined as a portion of memory that holds bits of software code you’ve used recently.
  • The more memory your machine has, the more that’s available for the cache, the faster things should feel to you.

Does ReadyBoost Really Work?

In theory, Yes, but not for every setup.

The Technical Part

  • An average 4K read from a flash device is about 10 times faster than reading from a 7200 RPM hard disk.
  • Thumb drives can be read very quickly (USB 3.0 thumb drives will even be faster).
  • Speed is because there is little to no seek time to read a thumb drive.
  • Hard drive seek time depends on how contiguous the data is and the amount of data being read.
  • All flash drives are not made equal.

Flash Drive Requirements

To work with ReadyBoost, the flash drive must be capable of:

  • 2.5 MB/sec throughput for 4K random reads and
  • 1.75 MB/sec for random writes

Will My Flash Drive Work?

  • Plug the flash drive in a 2.0 USB slot.
  • Did Windows offer the use of ReadyBoost in the dialog that pops up when you plugged the drive in? (Do you want to speed up your PC?)
  • If you get the offer, the flash drive or memory card is compatible and you're good to go.

Requirements for Using ReadyBoost

  • A PC
  • free USB 2.0 Port
  • Windows Vista or Windows 7
  • A Flash Drive
    • capable of 2.5MB/sec throughput for 4K random reads and 1.75 MB/sec for random writes
    • Between 250MB and 4GB in size (Vista 32-bit)
    • Between 250MB and 16GB in size (Vista 64-bit)
    • Between 250MB and 4GB in size (Windows 7 32-bit)
    • Between 250MB and 32GB in size and up to eight devices for a total of 256GB (Windows 7 64-bit

Enabling & Configuring ReadyBoost

Insert a USB flash device into a USB 2.0 or higher port.

Download Readyboost Windows 7 64 Bit
  1. The AutoPlay dialog box should be displayed automatically (unless you’ve changed the defaults in Control Panel).
  2. Click “Speed Up My System using ReadyBoost.”
  3. The device’s Properties dialog box opens to the ReadyBoost Tab.

Do one of the following:

  • If you want the device to automatically reserve the maximum amount of space for ReadyBoost, select “Dedicate this device to ReadyBoost”, then click OK.
  • If you want to use less space than the maximum possible, select “Use this Device” and then use the “Space to Reserve For System Speed' Slider or the combo box to set the amount of space to use for ReadyBoost, then click OK.

NOTE 1: If Windows decides that your drive is fast enough without ReadyBoost, it disables ReadyBoost entirely.

NOTE 2: You can use 1 flash drive per PC, and one PC per flash drive.

Security risks using ReadyBoost

  • Pretty small
  • Microsoft uses AES-128 to encrypt all data written to the ReadyBoost cache.

Alternatives to ReadyBoost

  • Use a Solid State Drive (SSD) for your operating system drive. $$$$$
  • Add additional memory (RAM) to your computer. $$

ReadyBoost Tips from Microsoft

  • The minimum amount of available space recommended for ReadyBoost to effectively speed up your computer is 1GB.
  • For best results, use a flash drive or flash memory card with available space of at least double the amount of memory (RAM) in your computer, and preferably four times as much memory.
  • For example, if your computer has 1 GB of RAM and you plug in a 4 GB USB flash drive, set aside at least 2 GB on the flash drive to get the best performance gain from ReadyBoost, and preferably the entire 4 GB. How much memory you need depends on how you use your computer. Keeping a lot of programs open at once uses more memory.
  • Give ReadyBoost 2 GB to 4 GB of space for best results on most computers. You can reserve more than 4 GB of space for ReadyBoost on most flash drives and flash memory cards. (Storage devices formatted with the older FAT32 file system can’t store more than 4 GB.) You can use a maximum of 32 GB of available space on any single removable storage device with ReadyBoost and up to 256 GB total per computer (by inserting up to eight USB flash drives or flash memory cards into the same computer).
  • To work with ReadyBoost, a USB flash drive must support USB 2.0 or higher. Your computer must have at least one free USB 2.0 port where you can plug in the flash drive.
  • ReadyBoost works best if you plug the flash drive into a USB port directly on the computer, rather than into an external USB hub shared with other USB devices.
  • If you want to be sure a USB flash drive works with ReadyBoost, look for a note from the manufacturer that the flash drive is “Enhanced for ReadyBoost.” Not all manufacturers list this on their packaging.
  • If there is no mention of ReadyBoost compatibility, the flash drive still may work with ReadyBoost.
  • There are many different kinds of flash memory cards, such as CompactFlash and Secure Digital (SD) memory cards. Most memory cards work with ReadyBoost. Some SD memory cards don’t work well with ReadyBoost due to issues with the SD card interface. ReadyBoost will display an error message if you attempt to use one of these cards.
