I think - if you are serious about the problem - you can just rely on  
a disk array to do this for you. You see something that looks like a  
disk but which is of course spread over lots of spindles and with a  
bucketload of NV cache in front of it, and which can sustain really  
high numbers of ops/second.

Of course that may be what the previous person meant by "special  
hardware".
