that's not fast.  a gigabyte an hour is fast.  100Mbyte/hour is quite low.
given that serious logfile-quality disk capacity costs less than $0.90/Gig
you should provision it in bulk.  treat logfile disk capacity the way you
treat printer paper or printer toner -- just keep buying it and using it up.
