ReadyBoost® Basics

• Windows® ReadyBoost® is a feature available if you have a Microsoft® Windows® 7, 8 or Vista Operating System.
• When enabled, the flash memory in products such as memory sticks, flash drives and SD cards is used by the computer as a cache.
• Because most flash memory devices have a higher random read/write speed than hard drives, a performance gain is obtained by using Readyboost®.
• Although Readyboost® improves the speed of random read/write operations, it doesn't get involved in sequential read/write operations, as the computer's own hard drive can do this best. ReadyBoost® therefore uses logic to recognize large sequential read requests and reads from the hard drive for these.

ReadyBoost Requirements

• The memory stick, flash drive or SD card must have a capacity greater than 256mb.
• The memory should have a 2.5MB/sec throughput for 4K random reads and 1.75MB/sec throughput for 512K random writes.
• The memory stick, flash drive or SD card should be 1-3 times the size of the RAM on your computer.
• Note that if you have a flash drive with more capacity than 4GB, this excess will not be used by ReadyBoost® due to limitations of the FAT32 file system

Initiating Windows® ReadyBoost® with a Flash Drive

• Plug in your flash drive into the USB Port on your Windows® 7, 8 or Vista PC.
• The following window should then appear:
  
• Select 'Speed up my system'

Setting a Flash Drive up for ReadyBoost®

• Assuming that you have plugged the flash drive in, and initiated Readyboost as above, go to 'My Computer', right click your flash drive icon and select 'properties'
• The following menu should appear, click on the 'ReadyBoost' tab
  
• 'Use this device' should be selected, and you can scale the amount of memory the computer can use for ReadyBoost®

Examples of when Windows ReadyBoost is Effective

• Readyboost® is especially useful when seeking performance gains from a computer lacking free expansions slots for RAM. Note however that if your computer has free RAM slots and you consistently find a lack of computer performance, there is no substitute for installing more RAM.
• ReadyBoost® is most effective for aiding RAM intensive programs

• Opening and closing of applications such as Adobe® Photoshop® and Microsoft® Word.
• Computer Games
• Heavy Internet Browsing (e.g. streaming content or multi-tabs browsing)
