Just one more piece of advice, you might want to look into a good battery backed cache hardware RAID controller. They work quite well for heavily updated databases. The more drives you throw at the RAID array the faster it will be.
I've seen this list often recommended such a setup. We'll probably get battery-backed write cache and start out with a 4 disk RAID 10 array. Then add more disks and change RAID 5 if more read performance is needed.
