Here there is a variety of desktop, laptop, and netbook hardware, spanning approx 5 years old to approx 20 years old. They come from many different manufacturers ranging from tier 1 to unbranded.
Kit supporting:
• USB v 1 is usually run in conventional hard disk mode and exclusively 32Bit,
• USB v 2 & USB v 3 is used in both hard disk and live modes, and mix 32Bit & 64Bit.
Systems are often cleared down and rebuilt for testing purposes, both CLI and GUI.
Providing the apps are carefully selected and purposed according to the capability of the hardware, and the OS is suitably fine tuned, acceptable performance is usually obtained.
