Windows Vista FAQ 2. Whats this I hear about thumb drives speeding performance?
. Instead of shelling out for extra RAM, you may be able to give your Vista machine a bit of a boost by using a USB thumb drive. A Windows feature called ReadyBoost lets your PC use free memory on a USB flash drive to augment RAM. You’ll need, at a minimum, a drive that has 256MB of free space and can read data at 2.5 megabits per second and write data at 1.5 mbps; to qualify for a Windows Vista logo, the drive must have 500MB of space and read/write speeds of 5 mbps/3 mbps. You’ll soon start to see flash memory boosting speed in other ways, too, thanks to the ReadyBoost and ReadyDrive technologies built into Vista.
