Partitioning 500Gb 7200rpm HD on my MacBook Pro 3.06Ghz
My MacBook Pro just came in!

I swapped the built-in 5400rpm with a new 500Gb 7200rpm HD.
I plan to do DESIGN PROJECTS using system MAC 10.6

and my VIDEO EDITING PROJECTS on WINDOWS XP using Pinnacle Studio 12 may be Adobe Premiere Pro ((in Full HD 1080p))...
This is how I'm thinking to partition my 500Gb 7200rpm HD (3 partitions):
Partition #1: 200gb for MAC OS 10.6

(all my Graphic softwares n projects)
Partition #2: 100gb for WINDOWS XP Professional (VIDEO Software)
Partition #3: 200gb for VIDEO Files (can I call this "DEDICATED HD?")
Pinnacle Studio and Premier Pro requires a dedicated HD at 7200rpm for Full HD video editing.
QUESTIONS:
#1- Can a partitioned HD be considered a DEDICATED HD?
#2- Is it better I do 2 PARTITIONS: one for MAC 10.6 and one for WINDOWS XP and buy an external/firewire DEDICATED HD for video? Please Let me know ASAP.
