Has anyone purchased these piano samples http://www.irishacts.com/

can anyone answer the following:

1 Do you need a hard drive to store these samples?
2 Can you use a memory stick to store the samples?
3 How long will it take to boot the Tyros 2 taking into the account the samples will need to be loaded from USB stick / Hard drive?

Many thanks in advance for any advice that can be given.
