I've always heard differing opinions on the subject of RAIDing non-identical drives together. In this case both drives are identical in size, but one is on a SATA II mSATA interface, and the other is a 2.5" SATA III SSD. Can I combine two identically sized drives with RAID 0, but with differing form factors and interface speeds? I'd be doing this with Intel's SRT.
Is it possible to stripe/RAID 0 a SATA II & III drive together?

Hey there, imrazor!
It's possible, but your performance gain will be non-existent since we are talking about striping/RAID 0. What happens is that when you RAID different drive, your array is limited to the speed of the slowest drive and to the capacity/capabilities of the weaker drive in general. Another thing you should have in mind is the fact that RAID 0 provides no fault tolerance or redundancy, so the failure of your drive will cause the entire array to degrade. This means losing the data on both, so make sure you back up if you decide to go with this configuration.
Good luck!
