| 1.8 still
great (after 27 years and still counting) |
Editor:- February 6, 2018 - A new blog by Virtium -
One-Point-Eight
Still Great! says that the company thinks "1.8-inch will remain
strong in embedded, IIoT and M2M applications for some time to come."
Editor's
comments:- 10 years ago there were 22 manufacturers of storage drives listed on
StorageSearch.com. The highest capacity 1.8" SSD at that time in 2008 was
128GB.
The 1.8"
storage drive form factor was created for the portable PC market with the
first drives being shipped in
1991.
M.2 was the designated
successor to 1.8" for SSDs in notebooks. But form factors can have a life
of their own.
For example - in 2011 1.8" SSDs with
SAS interfaces were a
hot product for use in enterprise storage arrays.
Nowadays if
equipment designers have gone to the trouble of supporting 1.8 SSDs (solo or
arrays) in legacy designs (with interfaces like PATA, SATA or SAS) then it's
still easier to continue supporting that in markets where requalifying the box
is expensive (like medical) rather than switch to M.2 for no customer
discernible benefit. In some markets
EOL is an expensive
option. | | |
