Enthusiasts are wholeheartedly adopting SSDs for their storage media of choice with HDDs relegated to long term storage of infrequently accessed storage.  For SMB and enterprise it is not such an easy choice as the expense to move to a purely SSD infrastructure is daunting and often not the most cost effective way to run their business.  That is why HDD makers continue to develop new technology for platter based storage such as HAMR and shingled magnetic media in an attempt to speed up platter drives as well as increasing the storage density.  Today at The Register you can read about a variety of technologies that will keep the platter alive, from Seagate's cached Enterprise Turbo SSHD, HGST's helium filled drives and the latest predictions on when HAMR and SMR drives could arrive on the market.

"At a briefing session for tech journos yesterday, Seagate dropped hints of new solid-state hybrid drives (SSHDs) - which combine a non-volatile NAND cache with spinning platters - and a general session about Shingled Magnetic Recording (SMR) and Heat-Assisted Magnetic Recording (HAMR)."
