New storage NAND system will replace Hard Drives

Fusion IO has developed a non-volatile PCI Express card with NAND memories for replacing hard drives. They will feature hard drives from 80 to 640 Gb. The worst is the price: $30 per Gigabyte.

I guess the first customers will be data centers since It will cut down prices on power consumption.
