Re: advice on computer extras as to AVID

Sorry, but I realize I must take your time once again.

1. you state that, "As far as internal hard drives, get one large enough to hold your sound effects and music libraries". A "Musical" productions is amongst my dreams (which I have scripted, storyboarded with 13 musical number). Given this, is it better to get an external drive, or would one of the configurations offered be best? ie:
a. 1 TB Serial ATA Drive
b. 2 TB ATA Drive [$135]
c. 256GB Solid State Drive [$450]
d. 1TB Serial ATA Drive + 256 Solid State Drive [$540]
e. 2TB Serial ATA Drive + 256 Solid State Drive [$675]

2. is the iMac's 3.4GHz Quad-Core Intel Core i7 processor fast enough to do the job, or am I already starting out on an inadequate foot? Know that I have other written and storyboarded script

3. is the 16 Ram upgrade advisable? Or is it unnecessarily high given the potential limitation of my processor?

By now you must see me as the true novice that I am.
Still, any other suggestions that comes to mind would be deeply appreciated.

Thanks,
Bill
