Which will have better real world performance?

[kaiweiler]

A single 80gb Intel X25-M or two Kingston SSDNow V-Series 64gb in Raid0?

Specs of both:
Intel X25-M

Kingston SSDNow V-Series

Definitely the X25-M. Although the V-Series are using an updated JMicron controller, it still comes nowhere near the IOPS of Intel's controller.

X25, no contest.
