unless you have already got a usb flash drive to hand thats readyboost compatible..vista will let you know if it isnt !
ive got a datawrite 4gb and its working fine, also, i can change how much i want to use for readyboost and for file storage so i get the best of both worlds.
however, the only problem i have is that i cant boot from my sata drive with it connected as my bios doesnt see the sata drive,tells me theres no op sys to boot from , although i can still get to boot xp/vista once i remove it.
...this isnt a readyboost prob though, it wont boot if theres any external drive switched on.
dunno why.
answers on a postcard please.
