I've yet to see a real PCIe SSD (i.e. not a PCIe card with some SATA

offer binary-only kernel modules for their SSDs, but I wouldn't want to
use binary-only drivers anywhere, especially in OBS.

Agreed. And then those beasts are really expensive. My customer simply
runs stuff out of tmpfs -- even faster than the FusionIO and no binary
crap needed

Yes, using tmpfs is faster, but you loose the persistance when power
goes off, and usually you don't have that much ram on your system :)

Since when do you need power-persistence for build roots? :)

I have tied a tmpfs to /var/tmp/jng-openSUSE_12.1-x86_64 and
factory-x86_64 so that at least the majority of my `osc build`
invocations run accelerated. I can't say I see much difference to a
system where /var/tmp is part of a SSD.
