should the swap file reside on a drive with data frequently accessed?

Hi,

Since I was running out of space on my old 40 GB HDD (C:) I recently
added a new drive. This was an old piece lying around so is pretty
small for today (20GB) I started by formatting it and added a small
2GB partition(E:) at its very "front" to hold my swap file. (I've 1GB
RAM)

The remaining 17odd GB are free for "data" as a seperate
partition(F:). C: remains my master-drive with all my Windows and
other programs installed there. I probably want to keep those
untouched.

But now I have a choice as to what components I want to move to the
new drive(D:)!

The three targets that come to mind are:
(1)MyDocuments,
(2)GoogleDesktop Index,
(3)Thunderbird_IMAP_Offline_mailbox (rightnow that's a MASSIVE and
SUPER fragmented file; makes TB very unresponsive at times)

In the descending frequency order of file access requests these
probably are: (2), (3) (1)

Which should I put on the new physical drive. Note that the first
logical partition on this physical drive holds my swap file. So I
probably don't want to have anything on D: that would detract from the
swap access function, right?

Any suggestions?
