BAD HARDWARE WEEK

A team of researchers claims to have come up with a power-efficient, scalable way to reliably store data with regular hard drives for an estimated (theoretical) 1400 years.
Moreover, a Pergamum system is comparable in cost and energy consumption to a large-scale tape archive, while providing much higher reliability, faster random access performance and better manageability.
Details are here.
Jim Gray vision of tape replacement with disks look at his Microsoft site. Alas, he passed his way last year.
