Larger faster new ssd vs 3 raid 0 older ssds

[hackmule]

I have a new ocz vertex 240 gb and I am currently running 3 80 gb intel ssd raid 0 on the motherboard controller. I have had a few near misses lately and decided to purchase the larger ssd to replace them so that I can back them up easily. (the usual backup suspects don't make disk imaging raid arrays esay). But I bench marked the 240 gb raid array vs the ocz vertex and they write about the same but the read speeds are 50% slower (500mb/s vs 250 for larger files). Boot time seems similar. Do you think I should use the raid 0 array or go with the single ssd solution?
