and even smaller number of remaining manufacturers of HDDs.
One trend are hybrid SSD+HDD drives (by Seagate).
With a $19B purchase of SunDisk WD can prepare for migration to SSDs.
But the technology is moving fast, and Intel + Micron have announced
a new type of permanent memory that is 1000 times faster than SSD
(while SSDs are 1000 times faster than HDD). Apparently coming in 2016.
In the meantime, the fastest SSDs are available from Samsung,
and only in "M.2" form factor, no SATA anymore, it is too large and too slow...
All this will even more accelerate "Cloud" storage and processing.
A few huge storage factories for a few huge clouds :)
