Moving to RAID - What Kind of Drive?

Question:
I would like to move from a single hard drive to RAID 1 in order to protect our site against our biggest point of failure. Given the configuration below, what type of hard drive should I get? I want to make sure it's not the bottleneck in my system -- nor get something faster than what I need. I also want the drive to still be adequate when I upgrade to 4gb of RAM.

Current Configuration - $234/mo fully managed
Q6600 processor
2g RAM
74gb 10k RAPTOR
.3 to 1.5 average load, low %iowait until backup time

Raid 1 Options
Dual 120gb 7200rpm SATA 8MB Cache + $20/mo
Dual 74gb 10k RAPTOR 8MB Cache + 60/mo
Dual 73gb 10k SCSI 8MB Cache + $100/mo
Dual 73gb 15k SCSI 16MB Cache + $120/mo

If you have any other feedback, I'd love to hear it. I'm not adept at checking for bottlenecks so if there's something I should look for, please share.
