The thinnest storage for your ultrabook... use the A: drive.
Might be best if they pick a different name to market it under... A-Drive smacks too much of floppies for my liking.
The Data Storage Institute (DSI), one of the many research groups at Singapore's Agency for Science, Technology and research (A*STAR), has taken the wraps off a hybrid disk drive said to consume less power than a comparable solid state disk while also being small and light enough enough to satisfy Intel's specs for use in …
If you never use more than 32Gb this drive will behave like an SSD, because everything you store will be cached in the solid-state part. The difference is that you won't run out should you want to store more. The stuff that you store and subsequently don't refer to for a long time will "disappear" into the magnetic disk. The stuff that is active will be solid-state cached.
Should be the best of both worlds.
Especially if it can tolerate complete failure of the flash cache, and revert to being a magnetic-only disk. Anyone know? The failure mode of solid-state memory is reportedly often to stop working in a flash (sorry). Magnetic disks can also fail like that, but more often degrade progressively and gracefully giving plenty of time to copy your data elsewhere.
