Flash memory has been dominated by two things of recent times:
- Capacity goes up
- Price goes down
There are prototypes that use magnetic charge (like a traditional hard drive) opposed to the [volatile] electric charge.
But what does this really mean?
It means that we are very close to having a non moving part PC. The average size of a hard drive in a laptop today is somewhere between 20 and 40 Gb (although this is trending up) so imagine being able to have 10 such SD cards creating a logical drive. This would take up much less space than a normal hard drive and would give the ability to swap out parts of the storage.
Think of it as SD raid.
