Carry what kind of lifespan? Generally I don't trust anything anymore and have a 2 local copy + one offsite policy for data I care about. If I don't have that I don't care enough about the data generally. As for storage and compute you mean memristors or fpga like? Solid state has a rather huge size difference to overcome. Hard to beat spinning rust at the moment and at least near future for bulk storage.
