The Mac uses only plug-in memory modules, its operating system automatically recognizes all the memory present, and all Mac software can share it.
Under its shiny new skin, new hardware and software, such as a slimmed down version of Apple's OS X operating system and a flash memory drive, instead of the current iPod's mechanical hard drive, could keep the new device thin and light.
Using a combination of HDD and flash memory in either a hybrid HDD or a dual storage notebook computer, where frequently used data (and possibly the operating system and application software) is kept in the flash memory, while the bulk of user content is kept on the HDD, has been shown to provide about 80% of the performance improvements of a pure SSD-based computer.
This is because the operating system and pre-loaded software are all on the flash memory.
FORBES: Will A Fusion Drive Approach Become Widespread in Computers?
As with any bare-bones kit, you'll need to install your own memory, storage, wireless networking components and operating system.
The laptop comes with 64M bytes of SDRAM (Synchronous Dynamic Random Access Memory) and Microsoft's Windows NT 4.0 operating system preinstalled.
Driven by rising multimedia use, present PC configurations are seeing greater memory and hard drive capabilities, on top of which a new operating system could drive PC unit gains toward the 20% year to year level in each of the next two years.
Red Hat, the world's largest Linux distributor, has provided an extremely compact version of its Fedora operating system, called Sugar, that uses a mere 130 megabytes of the XO's flash memory.
These approaches can combine a smaller SSD that stores the operating system and applications and a larger HDD that is used for user data, or a hybrid HDD that has flash memory inside a HDD that is used to store frequently accessed data on the flash with less used data kept available on the HDD.
