I think this is somewhat pointless as the reason for striping was to use both hard drive's spin speed to increase data rate where the bottleneck is always the hard drive. In this case, "conventional" seek time bottlenecks are eliminated due to the type of memory. Unless something is wrong with implementation, the default swap setup should be pretty much 100% of the speed you can get for "virtual memory". But there are far more factors than "it should work this way". Therefore, if many people are coming up with a much faster swap solution by switching to a class 6 card, maybe we can also see if we can't pinpoint the slow down? (ie. throughput, kernel handling, etc..)
