ReadyBoost 4GB or 8GB?

I honestly noticed no difference in my setup with a Corsair Voyager GT 16Gb USB stick in situ and RB enabled, as opposed to running without it. If your system is laggy in the first place maybe it would have a more obvious impact.

System was fine before and better after it, cannot talk for others but can tell you for a fact my system ain't laggy either way.

Corsairs 16GB GB 1st revision (there is a 2nd revision) were crap.

I returned mines for full refund as they were slower than even the slowest Non GT even though E-Tailers put up false speeds that Corsair did not even have on their site.

You can read the sticky on the Corsair Ram Guy forums if you wish.

I personally used a 2GB GT then a 4GB GT (the 8GB GT is the fastest and likes hen teeth to find now).

The 2GB Non GT I had failed Readyboost testing but some claim later revisions passed it.

I have the mark-II version, and it's not bad at all. The earlier version was what I originally had, and I can promise you it was RMA'd PDQ, it was total rubbish.

My favourite stick is the LaCie iamakey 16Gb, it looks just like a key

Update from last post:

Windows 7 supports up to 8 devices and 256 GB. Windows 7 features - ReadyBoost - Microsoft Windows

please note, 8 devices will max out a normal USB 2.0 bus, so i would suggest about 2 devices per USB bus unless u have 3.0.

I think we do get 5% to 10% improvment in prfomanace, but i got BSOD and my virus scanner is giving me problem always scanning and diabling my desktop gadgets.. well i will not sugest to go for readyboost.. better buy a RAM if needed ..
