Flash vs. hard drive battle heats up (Fortune)

What I wonder is "why not PCI" (or similar)?  Flash has the potential to go very, very much
faster than hard drives, particularly if you put down a parallel array of flash.  

Put some battery backed RAM a board with a controller and an array of parallel flash devices,
and you have a very, very fast "disk."  The battery backed RAM is there mainly to absorb
bursts of activity as well as sector translation maps for wear leveling.

It should be possible to get very fast speeds out of such a critter.  Maybe not as fast as a
RAM disk--that'd require fitting in a RAM socket and responding at RAM speeds and
latencies--but fast enough.

The only annoying thing is that BIOSes won't see it as a disk since it wouldn't necessarily
offer a disk interface.  I guess you *would* have to emulate some sort of legacy disk
controller interface for that, much like modern GPUs still support all the old VGA modes.
