The advantages and disadvantages of Flash Memory

Except for the iPod classic, which uses a hard drive, all iPods and the iPhone use flash memory chips for storage.
Flash memory has two main advantages:

• Flash memory is shockproof, so the iPod won’t skip unless you damage it badly enough to prevent it from playing.
• Flash Memory uses far less power than a hard disk – around 1/30 of the amount a hard drive takes – so the iPod or iPhone can run a good time on a smaller battery than it would otherwise need.

The disadvantage of flash memory is that it is still much more expensive per gigabyte than hard disks. This is why there is such a vast difference in capacity between the iPod classic(120GB) and the next-most capacious iPod, the iPod tough(32 GB)
