Generally speaking, Microsoft revealed that Windows Vista will install
in a traditional manner, and I mean via a DVD, from 20 to 25 minutes.
But there is a way of speeding that up considerably. You
will be able to deploy Windows Vista in 5 to 10 minutes. How,
you ask? Well, this is the main benefit of installing Windows Vista
from a USB 2.0 Flash drive.
The fact of the matter is that an ultra-fast USB 2.0 flash drive should
be an indispensable accessory for Windows Vista. You should take care
and choose a flash drive with 4GB of storage space and a read speed in
the vicinity of 25MBytes/sec. combined with a write speed of
14MBytes/sec. Once you have the flash drive, you are all set to go!
