Hybrid hard disc drives (HDD) containing a built-in layer of NAND flash memory may offer the advantage of consolidated storage for ultrabook laptops, but cache solid state drives (SSD) will remain the mainstream ultrabook storage solution, said market research firm IHS.
Cache SSDs will see their shipments rise even more this year to 2.39 crore units, up by a 2,660 percent from just 8.64 lakh units in 2011. Shipments will then jump to 6.77 crore units next year, cross the hundred-million-unit mark in 2015, and hit 16.30 crore units by 2016, claimed IHS.
In comparison, shipments of hybrid HDDs will reach 20.00 lakh units this year, up from 10 lakh units in 2011, on their way to reaching 2.50 crore units by 2016.
A third form of flash storage, dedicated SSDs that contain no cache component, will attain shipments this year of 1.80 crore in consumer applications, gradually ramping up to 6.90 crore units in 2016.
Consisting of a traditional hard disc drive and an integrated NAND flash layer within one self-contained form factor, hybrid HDDs are a new storage option being considered for the super-thin ultrabooks. In contrast to hybrid HDDs, cache SSDs are employed as a discrete, separate memory component alongside a hard disc drive, with both elements existing side by side, not together in one housing unit.
"The cache SSD solution was first hit upon by PC manufacturers because the use of a dedicated solid state drive proved too expensive when passed on to consumers in the retail market," said Ryan Chien, analyst for memory and storage, IHS. "However, a combined physical hard disc drive with a smaller cache component allowed PC makers to reap the advantages of faster responsiveness and larger capacities while keeping costs down."
In addition to the boot up time, I heard the Apps load much faster in an SSD compared to HDD. Recently ordered a 180GB Intel SSD from Amazon for my Macbook pro. Yet to stick it in and measure performance. Lot of my friends say a 3 year old notebook with SSD has better perceivable performance than a brand new notebook with HDD.

It saves more than a few seconds of embarrassment when getting into a meeting late and with people waiting for you to confess the failure analysis findings with cross-section evidence in your notebook, or whatever you call it.
I've been using hybrid HDD since Seagate released in 1+ years ago. Price is one of the reasons. The primary reason is actually capacity. I have a 500G which wasn't available in SSD at the time. Performance is better than a laptop grade HDD. System bootup time is not as impressive as when SSD is used. Yet, computer typically boots once in a day. It doesn't really bother me.
What's your experience with SSD or hybrid HDD?
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
