I don't have any advice, but being a novice in this area, 
I'd like to add some questions

o presumably not every file needs to be cached all the time, 
so you could use a hybrid drive with flash memory on it. Why 
don't people do this?

o what about using regular disks and having a PCIe card with 
flash memory acting as cache?

o how about using a (small) number of SSDs as cache (say 
with bcache http://bcache.evilpiepirate.org/)?

can anyone tell me the relative advantages?

thanks

Joe
