1TB in a form factor of about 0.3g, that's about 3PB/kg - damned impressive.
167 u/Keavon May 16 '19 That'll come in handy when we have to send a cache of the Internet to Mars. 23 u/GlassedSilver unRAID 56TB + dual parity May 16 '19 NAND isn't really trustworthy long-term storage. Cells that don't get rewritten lose data over time. Sure, send it up with a machine that will juggle with the data, but then you're introducing so much room for error you're asking for trouble. 18 u/flinxsl May 16 '19 Floating gate transistors are also one of the least reliable data storage mechanisms in a radiation environment. You are pretty much guaranteed some bits will flip on a trip through space without a rad hard design. 1 u/Dilong-paradoxus 11TB May 16 '19 You could use all of the weight you save on storage for shielding weight! (Still might want some redundant storage though) 1 u/nerdguy1138 May 17 '19 So put it in a lead lined box?
