In addition, flash memory is making its way into more enterprise and client computer applications, both as a stand alone storagedevice and as a cache memory and system accelerator.
Perhaps the biggest gain may be in dual storage computers where a flash memorydevice is used for storing operating systems, software and frequently accessed content (and maybe even for write caching) while a hard disk drive provides much less expensive mass storage of user data.
The limited camera (a rather basic 5 megapixel autofocus unit with an LED flash) and a paltry 4GB of onboard storage (mitigated by the 8S supporting a MicroSD for memory expansion) point to a device that has been built to carrier specifications and a specific price point.
Apple introduced its version, called Fusion Drive, that tiers storage on flash memory or a HDD depending upon frequency of use, but appearing to the user as a single storagedevice.
