Ok, now I think I'm beginning to understand why raid 0 does not appear faster than a single drive for desktop users. At qd 1 reads/writes are typically not faster when you go to raid 0, in fact they can even be slower.

Desktop systems are mainly qd1 or less so the read/ write speeds @ qd 64 etc have nothing to do with it. Even at qd 10, which will only happen rarely the benefit of increased read/ writes is no big deal.

For desktop it is predominantly all about low access performance at qd1. Sequential reads/ writes at ssd speeds don't mean a whole lot for desktop users. i.e read a 500MB file @ 500MB/s = 1 second, read a 500MB file @ 250MB/s = 2 seconds. No big deal.

Am I on the wrong planet or does this make sense?
