Hey everyone, I was wondering if anyone has used readyboost? and if so does it increase performance much at all. I have an LG flash drive but readyboost says its not compatible to use so what type of flash drive do you need to have as the LG I have is 2 gig capacity and only about 6 months old.

The less main memory you have, the more you will notice readyboost's help with performance.
Readyboost requires a usb 2.0 flash device between 250MB and 4GB in size.
It must be capable of 2.5MB/sec throughput for 4K "random" reads and 1.75MB/sec for "random" writes.
Many flash drive makers rate the speed of their devices using "sequential" read performance, which is not the same.

Thanks Hit Squad, ok why Im asking is my laptop is the not the fastest but the Vista adviser rates it as a Vita home or basic so waht should I look for when purchasing a readyboost flash drive? Also can there be some data on the flash drive or must it have no data stored on it at all?

Some new flashdrives have "Enhanced for Ready Boost" on them which makes it easier than trying to find the exact specifications of the drive.

You can select how much of the flashdrive to use as Ready Boost RAM, and the rest will remain available for files.

You can also use some SD memory cards for Ready Boost, too. For notebook PCs, this might be a better alternative since the card doesn't stick out like the flashdrive does, and you can leave it in most of the time.

Here's a brief description of the Ready Boost feature from Microsoft - Vista Ready Boost feature explained.

I have seen articles where ReadyBoost's speed increase is minimal or not existent in some cases. In some instances, ReadyBoost decreases speed. I've used it on an old desktop and it seems to work fine.

As a generalization, ReadyBoost works best in low memory situations (typically 512 mB of RAM) - and it's performance increase becomes less noticeable as memory increases.

That's true. If you already have enough RAM for Vista to run smoothly, ReadyBoost isn't needed.
