Instead, ReadyBoost uses the flash drive to store information that is being used by the memory manager. If you are running a lot of applications on a system that has limited memory, Windows ReadyBoost will use the flash drive to create a copy of virtual memory that is not quite as fast as RAM, but a whole lot faster than going to the hard disk. What is very cool here is that there is nothing stored on this flash disk that isn’t also on the hard disk, so if you remove the flash drive, the memory manager sees the change and automatically goes to the hard disk. While the performance gain from ReadyBoost is gone, you don’t lose any data and there is no interruption. And because the Windows Readyboost cache on the flash drive is encrypted using AES-128, you don’t need to worry about exposing sensitive data if the flash drive is stolen or lost. Also, the memory manager compresses the pages before writing them into the cache on the flash disk, which means you’ll get more mileage from each MB.

This application only uses virtual memory on Flash-disk drive as suppose to virtual memory off your hard-disk??
 
I still don't get this technology. Surely a Hard drive has faster access times to read/write than a memorystick on USB2?

Q: Aren't Hard Disks faster than flash? My HDD has 80MB/sec throughput.

A: Hard drives are great for large sequential I/O. For those situations, ReadyBoost gets out of the way. We concentrate on improving the performance of small, random I/Os, like paging to and from disk.

Howmuch does ReadyBoost cost ??? or is it available online ?

Is it for Vista alone ? or will it work just as good on normal XP pro?
 
This is one of Vista's selling points with DirectX 10. I gues you'll never see it on XP unless a third party creates something.
 
Windows Vista has some promising stuff ahead! Can't wait to down...uhhh buy it:D
 
stick usb drive in, IF it is bigger than 256mb, and IF it supports a fast enough transfer rate, THEN the autoplay dialog will give you an option to use readyboost.
 
Has this readyBoost made a noticeable difference to anyone?

And how big were the drives used?
 
I actually forced readyboost on an earlier thread on myadsl ;) It did slow my pc down, but I was a sucker for punishment. You do need a fast, capable flash drive in order to feel the kick :p

I forced it: ie. I used a flash drive that wasn't fast enough and I forced the readyboost feature to work. I know the Trancend Jetflash range flash drives of 2007, that support Vista are really cool with readyboost ;)

*Looks at 2GB Transcend jetflash next to him and contemplates...

Think it will speed up even if I have 2Gb RAM already?

Well I will give it a shot...

I tried a 1GB one and it said it wasn't fast enough? :confused:
 
I got my new Sandisk cruzer 4GB flash disk last week and decided to use it with the Readyboost on my new laptop as it only has 1GB RAM and was struggling abit with Vista, and it has made such a big difference. Vista loads up so much quicker and I can have quite a few programs running while playing music and games. Definately a good feature :rolleyes:

Yeah, I think it might help if you have little RAM, like <2GB...
 
Quite interesting, it can only use 4,090MB of my 8GB flashdisk. I assume that is the maximum space Readyboost can use of any size flashdisk?
