Re: Upgrading Load Source Disk

[DrFranken <midrange@xxxxxxxxxxxx>]

Actually it's the other way around, the bigger drives, because they have 
more data on them, get used more and can get 'hot'.  This is why the 
rule of thumb is no drive MORE than twice the size of the smallest drive 
in the ASP.  So 35s and 70s would be within the rule, but 25s and 140s 
would not.
