ReadyBoost changes in Windows 7

[estra]

Came across the following information that discusses how ReadyBoost has been improved in Windows 7 as compared to Windows Vista:

ReadyBoost is a feature that was introduced in Windows Vista, allowing a flash memory device (such as a USB flash drive or SD card) to act as a memory cache. This assisted with increasing a PC's performance, especially when physical memory was limited or not upgradable.

Windows 7 has improved the capabilities of ReadyBoost over Windows Vista, including:

* Maximum cache size has been increased from 4GB to 32GB. Note that to utilize a memory cache of greater than 4GB, the flash drive needs to be formatted with either a exFAT or NTFS file system.

* Support for up to 8 ReadyBoost devices simultaneously on the PC. Windows Vista only supported a single ReadyBoost device per PC.

* The ReadyBoost cache can be used during boot to improve startup performance.

The ReadyBoost UI itself hasn't really changed in Windows 7, other than an added option to dedicate the device to ReadyBoost. In Windows Vista, there were only two options – use or don't use the device for ReadyBoost.

Of course, it still holds true the the best option, if possible, is to upgrade the physical RAM to increase system performance. However, when this isn't an option or if you have some extra space on a flash drive that you are not using, ReadyBoost is there as an alternative. A prime example of where ReadyBoost shines are Windows 7 netbooks that only have 1GB of RAM installed. Having a ReadyBoost cache of 2-4 GB will have a noticeable effect on system performance.

Note that if you are using a Solid State Drive (SSD) in your PC, you will likely not have the option to use ReadyBoost when inserting a flash memory device. This is because in general, SSD drives are fast enough so that there would be no benefit in using a ReadyBoost device over the SSD.

Nice read estra, thanks a ton !

I have tried ReadyBoost on occasions in Vista but havent found it to be worth all the hype ...

hi !

thanks for the info estra.

interesting that readyboost supports 8x32GB, you need to have a lot of RAM-memory to be able to use so much readyboost-memory.

but, if you have a lot of RAM-memory, why do you need readyboost ?

That's very informative. Thanks estra.

I used to use my UFDs with ReadyBoost but no longer now.

Thanks for Information. In addition, Windows 7 doesn't have any a ReadyBoost service now ... So it definitely free's up some MB of main memory of those who don't use ReadyBoost.

I did not see it to add much to performance either. But it did reduce the disk activity significantly. That in itself was a good thing.
