A question about System usage of HDD

[Hero]

Hi
I know you are at least as old as twice mine and can be a godfather for about half of us here...
Thanks for your advise.But I should say sometimes I type exactly comes out of my mind withoutout thinking(a bad habbit...),and it sometimes make some misunderstandings.
Sorry if I told something bad,It was only strange for me,somebody using that much HDD except be a server,then I used that word.

In addtion,a question about what you mentioned:Is it possible to use RAID if you have 2 HDD with deferent sized for only one of them?
For example my Storage contains 2 HDDs: 80GB SATA+250GB SATA.
Is it possible for me to use RAID for 80GB drive?if yes,How I can enable it in Windows XP?

sincerely yours
