The reason that Fujitsu has elected not to release a Hybrid Hard Disk Drive (with flash onboard) or a Solid State Disk drive has to do with the reality of their performance and market demand. While there is significant hype in the media, there is very little demand from users for these units (Gartner DataQuest estimates that 96K PCs shipped with SSD in 2007 vs. 164 Million 2.5" HDDs. That is much less than 1% of the market). Most of the SSDs were positioned as a performance play, the reality is that they beat HDDs only in Random Reads applications, while HDDs outperform SSDs in Random Writes, Seq. Reads and Seq. Writes. So Flash or SSDs make sense in Random read applications(e.g iPod). SSDs have also been hyped for power benefits when in reality the LCD Screen and CPU are the power drain issue. The use of SSD has been shown to increase the battery life of a HDD notebook by less than 5% (15min improvement for a 5 hour battery life with HDD due to HDD use of SATA power save modes). There are also statements to the shock benefits of SSD, in reality the weak link in notebooks is the Screen. Most mobile HDDs have shock sensors and retract the HDD heads to the ramp load area for 1000G non-op shock performance even if operating at the time of the fall. Thus, the notebook screen is more likely to be damged prior to an HDD or SSD shock event). While I do feel that SSDs will address their performance problems in the next few years, there are still signifcant cost disadvantages, wear leveling and cell writability limitations to overcome.
