Thanks for all the responses!
I am now thinking of:
Adding 2 SATA drives
1 for raw data
1 for rendered images.
This link, https://faq.storagereview.com/tiki-index.php?page=SingleDriveVsRaid0 has more details, but that seems like a good, balanced price/performance for a single user doing video editing.
In the past (using pinnacle), the cpu was not used too much and commit charge / peak hovered at just under 1 GB, which would lead me to believe cpu in under used waiting for I/O, ram could use a little boost, but not taxed.
Still awaiting the box for vegas though, and eager to get a hw config setup.
Thanks again!
All ideas are appreciated!
