The density of non-volatile flash memory has increased to where it has become possible to squeeze tens of gigabytes of storage into the space of a single 2.5in hard drive. Let's face it, you can get 8Gb into an iPod Nano, and that has to have a display, buttons and an earphone socket. Now the memory makers are turning their attention to applications in IT by packing the chips into storage drives for laptops and for servers. Intel believes there is a huge market waiting to be tapped in solid-state flash drives.
