For whatever it's worth:
It seems like the landscape is changing with advancements in computer technology. It makes you wonder about the viability of HDD's in the future.
A lot of the stuff out these days doesn't have a HDD at all. It's just a small data storage chip soldered to the mainboard of the device. Not all that different than the inside of a thumb drive. 32 - 128 Gb of storage is far more than enough for a device that automatically backs up to the cloud.
That might be one reason why the smaller companies gradually withered away ? Diminishing supply ? Rapidly dwindling profits ?
I doubt that HDD's will ever completely exit the scene but it might become difficult to be a company that specializes in just one thing. You might have to diversify and develop other income streams in order to keep the business profitable.
You know ... adapt to a changing environment ?
Last i knew ... DDR 4 memory is slated to make it's mainstream debut sometime in 2019. I don't think i would get too heavily invested in anything that has a data transfer rate less that 6 gb/sec. The older stuff is likely to be rendered obsolete.
Anyway .... welcome to the forum ... best of luck !
