Should I move my Swap Partition from my SSD to the platter?
 
I love the way my Patriot Inferno SSD boots up. It takes about 13 seconds from
GRUB to when I start to hear music... But I was wondering if I need my swap
partition to be on the SSD, i.e. my spinning disk also has a S.P.
I have 8GB RAM, so I don't know if I'm even writing to it.
Q9550, Palit GTX460-2GB, Evga 9800GT, 60GB inferno SSD, P5N-D, Zumax 650W,
Unbuntu 10.10, and 11.04
TNX!

I would leave Swap on the SSD. You want swap to be quick, and as you've alluded to, with 8GB RAM you are probably not going to be using swap.

To check your memory and swap usage type: free -m in terminal.

Well, you're probably writing to it even if you're not using all your RAM. The kernel will swap unused pages to disk even if there's not much memory pressure. You can tune that with the vm.swappiness tunable.

As Zetec said, when you do hit it, you want it to be fast, so leave it on the SSD.
