The shipment numbers cover pure standalone SSDs - i.e., units with no HDDs associated with them - as well as when the drives are used with HDDs as separate cache SSD entities. These numbers cover all applications for SSDs, including the enterprise segment, ultrabooks and other so-called ultra-thin computers.
"Intel has not matched its ambitious goals for ultrabooks with the marketing needed to propel the platforms as a desirable, affordable alternative to conventional notebooks and tablets," said Ryan Chien, analyst for memory and storage at IHS. "This has prompted IHS to lower its cache SSD shipment projection. However, pricing for SSDs has fallen well below the $1-per-gigabyte threshold, making their value proposition more attractive than ever. Because of this, SSDs are finding uses in other products, helping to compensate for the shortfall in ultrabooks."
IHS is maintaining an aggressive long-term outlook for SSDs due to NAND die shrinks, increasing utilization of TLC flash, and controllers with more advanced flash management techniques that are accelerating the cost curve.
The second quarter of the year closed with 7.1 million SSDs being shipped for $1.5 billion in revenue.
And although cache SSDs undershot expectations, traditional SSDs-including those for the enterprise market - with their higher prices helped make up the revenue slack.
By the second half of this decade, SSDs will be a de facto standard in non-budget notebook and desktop PCs, thanks to a mixture of lower prices, consumer education and an optimized software ecosystem.
IHS projects the SSD industry will finish 2012 with $7.5 billion in revenue and 41.0 million in shipments, with CAGR of 35% and 69%, respectively.
