How popular is the 3.5" format for
SSDs? - by Zsolt
Kerekes, editor
It has changed over time. A decade ago it was
the most popular form factor out of the
hard disk sizes.
That level of interest has declined (partly due to fragmentation
because there are more form factors for enterprise SSDs such as
M.2,
PCIe slots and
DIMMs) but
nevertheless 3.5 inch form factor SSDs remained in the
top 20 SSD
articles on StorageSearch.com in June 2016.
In the 3.5" package we used to find
hard disks,
hybrid drives,
flash based SSDs
and even
RAM SSDs competing for
slots, often with exactly the same interfaces. You can see some examples of
past 3.5" SSDs below.
The product shown below, from
Mtron (which is no longer
in business) was the most
popular product
here on StorageSearch.com in the period August 2007 to October
2007.
The product shown below, from
Memtech (acquired by
STEC in 2005) is an
example of a 3.5" PATA
SSD product featured here on StorageSearch.com in 2004 - the AT3550
Wolverine.
BiTMICRO was one of the earliest companies to talk
realistically about deploying flash SSDs in the
enterprise SSD
market - and published articles and case studies supporting this view.
In a 2004
case study BiTMICRO showed how a single 3.5" flash SSD speeded up a
25,000 user server by 15x compared to the previous hard disk system.
The
BiTMICRO ad (below) shows an SSD which the company started shipping in
November 2008 and
advertised here in
2009.
If a user has been
deploying SSDs in their datacenter for 5 to 10 years already - they will have a
different set of ideas about product preferences to another user who has less
experience and less confidence about SSDs.
