There is lot to know about Windows 7 ReadyBoost feature. There are many types of USB flash drives available in the market, but not all can be used for ReadyBoost. In this post I am giving some tips on how to check whether your device can be used for ReadyBoost or not and how you can use it.
Windows 7 ReadyBoost tips
ReadyBoost in Windows 7 has undergone a lot of change. It can speed up your computer by using storage space on most USB flash drives and flash memory cards. When you plug a ReadyBoost-compatible storage device into your computer, the AutoPlay dialog box offers you the option to speed up your computer using ReadyBoost.
If you select this option, you can choose how much memory on the device to use for this purpose. When you set up a device to work with ReadyBoost, Windows shows you how much space it recommends you allow it to use for optimal performance.
For ReadyBoost to effectively speed up your computer, the flash drive or memory card should have at least 1GB of available space. If your device doesn’t have enough available space for ReadyBoost, you’ll see a message telling you to free some space on the device if you want to use it to speed up your system.
If you want to use an USB device specifically for this feature, you can turn on or turn off ReadyBoost - it eliminates the requirement of setting up your device for ReadyBoost every time you plugged it in.
Here are some tips on what to look for when selecting a USB flash drive or flash memory card to use with ReadyBoost:
- The ReadyBoost tab lets you decide how much storage space on a removable device to use for boosting your system speed.
- The minimum amount of available space recommended for ReadyBoost to effectively speed up your computer is 1 GB.
- 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 might 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 a warning message if you attempt to use one of these cards.
What types of memory devices may not work with it:
- If your computer has a hard disk that uses solid-state drive (SSD) technology, you might not see an option to speed up your computer with ReadyBoost when you plug in a USB flash drive or flash memory card. You may instead receive the message, “Readyboost is not enabled on this computer because the system disk is fast enough that ReadyBoost is unlikely to provide any additional benefit.” This is because some SSD drives are so fast they’re unlikely to benefit from ReadyBoost.
- In some situations, you might not be able to use all of the memory on your device to speed up your computer. For example, some flash memory devices contain both slow and fast flash memory, but ReadyBoost can only use fast flash memory to speed up your computer.
If you want to monitor Readyboost, you may do so with ReadyBoost Monitor, whose link is given at the end of this post.
