Booleans generally should be reserved for logic operators. Most of the
Linux companies work on both low and high end storage. The two are not
mutually exclusive nor do they divide neatly by market. Many big clouds
use cheap low end drives by the crate, some high end desktops are using
SAS although given you can get six 2.5" hotplug drives in a 5.25" bay I'm
not sure personally there is much point

(and I used to have fibrechannel on my Thinkpad 600 when docked 8))

Send patches with benchmarks demonstrating it is useful. It's really
quite simple. Code talks.
