I think the poster of that vid does not understand why SSDs are faster. He let's you show an ATTO-benchmark which tests only sequential I/O; that's absolutely not the reason SSDs are faster and a 350MB/s sequential read is a poor performance for two SSDs in RAID0 anyway.
The real gain, of course, is IOps. But that term does not mean anything to a large amount of pc users. Still, it is what actually makes these SSDs so fast; not their double sequential speeds.
