OCZ to come out with new VERTEX SSD,S equiped with 64MB OF CACHE starting at $129

A 1000 drive RAID 10 will make huge IOPS and be slower than a single good SSD, for a home user of course. Above some point it doesn't reduce anything. Exactly like core count.

Sure, because that HDD array will take the same 12ms (or however fast the drives are) to do 1 IO and several hundred IOs. If the task requires less than that several hundred IOs per 12ms then the number of max IOs doesn't matter anymore (it might as well be millions per 12ms) as the access time becomes the constraint.

You have to realize that with SSDs those IOPs limits are ~100 times higher than that of the HDDs due to the access times. I highly doubt things are truly maxed out in terms of the IOPs at the current performance numbers.

Is there a program that records the number of IOs going to the array that we can run in the background to measure how much apps really use when they load?
