[G4] Question about HD Storage

[Kevin Willis]

	I have been turning my kids VHS tapes to DVD recently.  I capture 
using Alchemy TV, then I import them to iMovie HD where I add the 
chapter markers and use iDVD to encode and burn them.  It used to take 
over 2 hours to import the file to iMovie.  Recently, I created a RAID 
using 2 40 GB ATA drives and installed Panther on it.  Today I captured 
my first movie on it and imported it to iMovie.  The importing only 
took about 20 minutes to import this time.

	Could faster importation be because I am using a RAID, or is it 
because I am using a clean hard drive?  Before, I would do 1 movie then 
delete it then do another movie etc.  Does rewriting over the same 
drive cause a slow down over time?

Thanks

Kevin
