Of course, you're probably familiar with how we use ours, Dave. We have
a 128MW SSD used as cache, and I believe swapping. There are times that
I'd like to experiment with it - like using it for 2-electron integrals.
But for that case it's not really big enough to be used by more that one
person at a time.
I tend to to think that unless a very similar SSD-like device is available
on a wide variety of machines it is not worth the effort for end users to
put much time in optimizing a program for SSD usage.
Relatedly (and this should probably be a separate thread), I find it
difficult to make good use of asynchronous i/o.
