VMS already has caching, and it works quite well.  We configure with 
lots of memory.  Enough cache to contain all the data files.  Not saying 
that always happens.

Not much benefit from contiguous files on a SSD.  Some, but not anywhere 
near as on a disk.

The RMS file internals usually benefit from optimization.  Used to do 
some of that.  Don't miss it at all.
