Ok,
So reading out TWO streams serial from each disk would give the speedup,
wouldn't it?
The driver would just have to cache the four(6,8,..) streams until they are
merged?
So the driver has just to cache two streams per disk and all would be
perfect...?
Just as proposal for the future
Hello, I hit a bug in mdadm.
According to --manage --help this must work, but it doesn't:
-bash-3.2# mdadm --manage -a /dev/md2 /dev/sda3
mdadm: /dev/sda3 does not appear to be an md device
But this works fine:
-bash-3.2# mdadm --manage --add /dev/md2 /dev/sda3
mdadm: re-added /dev/sda3

This looks like a potentially good, cheap candidate for md use.
Although Linux support is not explicitly mentioned, SiI 3124 is used.
