Very useful post, thanks. I'm just nitpicking here about the use of
RAID0 on a single physical drive, which doesn't seem useful IIUC.
RAID0 alternates stripes between two physical drives so that one disk
can be reading/writing while the other disk's heads are seeking, no?
If that is the case, then single-disk RAID0 will just be thrashing the
heads back and forth between stripes on different partitions, making
more work for itself than necessary.
If I'm wrong about this, someone please correct me.
