Actually, my experience is that most linux file system developers have 
really poking, aged hardware with little to no cutting edge storage (or 
even cutting edge commercial class storage). Testing file systems on lap 
tops and desktops with old CPUs, no DRAM and 40GB drives does not even 
reflect a typical home user these days :-)
