I expect them to be just as competetive as motherboards, at least in
the past.  The fact that there are only 2-3 surviving HDD
manufacturers indicates intense competition in the past, possible less
today.

What makes you think so.  The DRAM chips on DDR4 DIMMs today hold
512MB (x8->4GB DIMM) up to 2GB (x16->32GB DIMM).  There are 2GB DDR3
DIMMs (using 256MB chips), but they do not cost less than 4GB DDR3
DIMMs.  Choosing a DRAM cache of 256MB rather than 512MB is unlikely
to save even one cent.
