Hybrid HDDs Make Gains, but Cache SSDs Reign Supreme: IHS
The proliferation of thin Ultrabook notebooks will keep cache solid-state drives as the storage market leader, IHS reports.Cache solid-state drives will remain the mainstream storage solution for Ultrabooks and other super-slim notebooks, according to a new study from IT research firm IHS iSuppli. The study noted, however, that hybrid hard-disk drives, which contain a built-in layer of NAND flash memory, may offer the advantage of consolidated storage in the Ultrabook format, which is becoming increasingly popular as more advanced models from major vendors hit the marketplace. Shipments of cache SSDs, which are employed as a separate memory component alongside an HDD (not together in one housing unit), are projected by IHS to rise to 23.9 million units this year, up by a whopping 2,660 percent from just 864,000 units in 2011. The research indicates the market has nowhere to go but up, with shipments jumping to 67.7 million units next year and crossing the 100 million-unit mark in 2015. By 2016, IHS is projecting shipments of cache SSDs will hit 163 million.
Meanwhile, shipments of hybrid HDDs are expected to double this year to 2 million, and will reach 25 million units by 2016. The report projected a third form of flash storagededicated SSDs that contain no cache componentwould reach 18 million shipments this year in consumer applications, a figure that will ramp up gradually to 69 million units in 2016, as ultrathin notebooks continue to gain market share.
