Except for price/GB, it is game over for HDDs. Since price/GB is based on

SSD's are a sufficiently new technology that I suspect there's significant
probably of discovering new techniques which give larger step improvements
than Moore's Law for some years yet. However, HDD's aren't standing still
FLASH technology is highly mature and has been around since the '80s.
Given this, it is perhaps the case that (through continual refinement)
FLASH has finally made it to the point of usability for bulk mass
storage. It is not clear if FLASH will obey Moore's Law or if it has
already started its trailing off stage (similar to what happened with
single-core CPU performance).
Only time will tell. Currently (after rounding) SSDs occupy 0% of the
enterprise storage market even though they dominate in some other
markets.
