easier to implement in controllers and propagate in the industry.


At


the same time, SED capability is a distinguishing product feature for those SSDs that have it and a potential negative purchase factor for those SSDs that don’t include it. This is because, by incorporating SED capability in controllers, customers don’t pay extra for the security features. This makes SED SSDs more attractive to customers even if they have no active plans to use the security features.


Thus Coughlin Associates projects that within two years (by 2013), SED capability will be in over 80% of SSDs and likely in almost all SSDs within three years (2014).


The markets where Coughlin Associates would expect the greatest interest in SED SSDs include Financial and POS, Servers, Notebook PCs, Desktop PCs, Military and Aerospace and NAS and SAN. Altogether these account for over 90% of all SSDs.


Figure 1 gives the Coughlin Associates model of SED SSD security adoption (actual use of SED security features). High, media and low estimates are made for these based upon the projections in Figure 10. Although actual SSD SED feature implementation in 2016 is likely to be about 100% in about 122 M SSDs, the projected actual SSDs from that year used for security and data protection purposes is estimated at less than 18 M units (these are mean values only).

The SNIA Solid State Storage Initiative (SSSI) fosters the growth and success of the market for solid state storage in both enterprise and client environments. Members of the SSSI work together to promote the development of technical standards and tools, educate the IT communities about solid state storage, perform market outreach that highlights the virtues of solid state storage, and collaborate with other industry associations on solid state storage technical work. SSSI member companies represent a variety of segments in the IT industry.
