Storing Data For The Next 1000 Years
Tom's has a nice article on a bit of research done on data storage

Pergamum, named after the ancient Greek library that made the
transition from fragile papyrus to more durable parchment, is designed
as a distributed network of individually fully functional network
storage devices. Compared to current MAIDs (Massive Arrays of Idle
Disks), NAND flash memory (described as on-volatile random access
memory - NVRAM) within the project has been added to each node with the
purpose to store data signatures, metadata, and other small items,
allowing deferred writes, metadata requests and inter-disk data
verification to be performed while the disk is powered off. Since the
NVRAM can run frequent searches without the need to spin up a hard
drive, the disk media can remain powered down more often, effectively
reducing wear as well as the power consumption of a MAID.
