Hard Drive swap advice~!?

Hi all,
So I currently have a WD Caviar Blue 500GB drive (16mb cahce, 7200 rpm, 3gb/s interface)
but I just received an RMA WD20EARS which is a 2TB drive caviar Green (64mb cache, ?rpm, 3gb/s interface)

Now I'm wondering what would be the most optimal set-up for my computer...should I run the OS from the new drive because it's bigger and bigger cache? I know the caviar green's are energy efficient so they don't really tell you the rpm, but it's supposedly supposed to be as fast as 7200 rpm, or does the cache improvement trump the rest of the specs anyway?

any thoughts?
I have been getting annoyed at long load times for starcraft 2...i've added some ram, upgraded my vid card so now my current configuration (without new hdd) has my Primary hard disk as the lowest score for the Windows Experience Index (at 5.8)... I'm hoping this might be able to help...

WD Blues are a little faster than the Greens. I'd leave the OS on the Blue and use the Green for storage.

I'd put the OS on one and the fixed size swap (and temp files) on a small, FAT 32 partition on the outer edge of other drive.

1. Writes to swap can happen independently of what other drive is doing so no waiting for heads to finish doing one thing to start the writing and reading to / from swap.

2. FAT32 has lower overhead than NTFS so will pick up small % speed increase there. Not like ya need NTFS file protections on a swap file.

3. Outer edge is fastest part of drive. Put the swap there and keep it there.

Agree with jsc.

But if load times are truely annoying you, get a SSD for a boot drive. An OCZ Agility 2 60GB SSD from MicoCenter cost me $119, after rebate.

Then you the blue for storage (Documents, Downloads, Music, Pictures, Videos), and the green for backups (everything!).

BUT, what is your OS? Windows 7 has native support for SSDs. Wouldn't go any other way.

What mobo? I think you do, but you want at least SATA II drive support.

Yes it has sata2 support

I've heard the blues are faster than green's, but I wasn't sure if the fact that it's an old blue (like from 4 years ago) that a bigger and newer drive could be better (wasn't sure if the bigger cache may make it better?)
So if that's not the case, then it sounds like everyone thinks putting my Windows7 onto the 500GB Blue drive, and using the 2TB green drive for storage.

In terms of what JackNaylorPE do I go about doing all that... sounds complicated. Anywhere I can find a step by step how to?
And does that actually work?

what about doing a RAID setup?

Yes, and "short-stroke" the system partition, because
of the phenomenon illustrated so well in these graphs:

All HDDs maintain at or near the same recording density
from outermost to innermost tracks, so the inner tracks
necessarily have less data because their circumferences
are smaller (PI x diameter):

You can shrink C: very easily with Partition Wizard
AND it will automatically defrag every file in the
reduced partition:
