Sata3 vs sas vs ssd

[skaiter1007]

i am about to build a new system and want the fastest hard drive for the money. only need about 120 gbs because this is just for OS/apps. system i'm going to build will be

i7 920
6gb 2ghz ram
asus rampage series (not sure which one yet because of the hd IOs i will need)

been looking into a 15k sas, 10k sata 3, and ssd drives

i've heard good things about the intel x25 ssd in terms of reliability, but it's very costly (around $400 from what i've seen) are there any other ssds that are anywhere close to the intel?

thank you for any help
Justin

You could get the Corsair F120 SSD, it costs around 300$ and it's a lot faster than the Intel SSD, the Cheetah and the Velociraptor.
