In recent years the
2.5 inch form factor
has been one of the most crowded parts of the
solid state disk market -
with new oems entering the market every day. At stake are the
applications described in our
SSD Market
Adoption Model. See the
SSD market research
page for more info about market size.
The 2.5" form factor is
the only size which straddles the wide range of SSD application slots.
The technical characteristics of the ideal 2.5" SSD product varies
considerably from design slot to design slot (sometimes
raw speed,
othertimes capacity,
reliability, the
ability to recover
data, or the converse,
TCO, initial price
or power consumption and even weight). These are often conflicting parameters
and cannot be met by any single product. However, the overlap of capability and
technology between some high volume applications and the sheer number of oems
guarantees a very competitive market - from which users will benefit much
sooner than predicted by out of date graph theory projections proposed by
classical
storage analysts.
Number
of manufacturers making 2.5" SSDs? - over 100 current SSD oems
with most of them listed
here.
Most popular interface? -
SATA
The fastest
2.5" SSD today are 6Gb/s
SAS models. See the
fastest SSDs for
details. In future the fastest 2.5" SSDs will have
PCIe interfaces -
2.5" PCIe SSDs.
This concept has already been demonstrated in
3.5" SSDs.
In
August 2011 - the highest capacity 2.5" SSD was 1.6TB - first
sampled by SMART.
It's
technically possible to build multi-terabyte 2.5" SSDs today - but the
interfaces in the 2.5" form factor and the market apps don't justify the
economic deployment of this type of product yet. Instead - if you want higher
capacity - you can get 10TB SSDs in a
PCIe SSD module from
Fusion-io.
