How to Enable and Use ReadyBoost in Windows 7 and Vista

[naeemprince]

Windows ReadyBoost allows user to make use of relatively cheap USB flash drive, memory stick or memory card as extra additional disk-based cache memory to speed up and boost performance of Windows Vista and Windows 7 operating system, and improve system responsiveness. Windows uses ReadyBoost memory to supplement the existing virtual memory, which is stored on slow hard disk drive.

In order to be able to be used as the virtual memory caching storage medium by ReadyBoost, the removable media will need to meet the following hardware and speed requirements:

1. The capacity of the removable media is at least 256 MB (or 250 MB after formatting).
2. The flash memory devices must be capable of 2.5MB/sec throughput for 4K random reads spread uniformly across the entire device.
3. The flash memory devices must also be capable of 1.75MB/sec throughput for 512K random writes spread uniformly across the device.
4. The removable media device should have an access time of 1ms or less.
5. The flash media must have at least 235 MB of free storage psace.
6. Formatted as NTFS or FAT32 filesystem, both can make use a maximum of 4 GB of flash memory, which is the ReadyBoost limit, and in FAT32 case, the ReadyBoost.sfcache file size is also limited by FAT32 filesystem to 4GB.
7. ReadyBoost supports one flash device at any one time as of currently.




Of course, ReadyBoost won’t outperform adding additional physical RAM memory, but it’s a good alternative for users with existing or spare USB flash drive to gain some free speed boost. Here’s how to turn on and enable ReadyBoost on Windows Vista and Windows 7 system.




# Insert the USB 2.0 flash drive (memory stick, thumbdrive, pendrive, key drive and etc) into USB port, or a memory card (SD, SDHC MMC, CF, MS, xD and etc) into a card reader.
# On AutoPlay pop-up window, select Speed up my system using Windows ReadyBoost.
