The relevant XKCD from January 2013 addressed the bandwidth of a station wagon full of tapes. It then shifted into microSD cards, whose density works out to 160 terabytes per kilogram. But those seem to have been 64Gb cards at the time (see label on milk jug). https://what-if.xkcd.com/31 https://what-if.xkcd.com/31
If you upgrade to 1Tb cards, that's about 2.5 petabytes/kg.
- visarga 8y agoThat's a pretty expensive wagon, though, at 1.4m$/kg. Maybe it would be more profitable as contraband.
- teraflop 8y agoI think you mean 2500 TB/kg, not PB/kg.
- mattmar96 8y agoSame difference
- Causality1 8y agoIf you're going to be tetchy about base 2 and base 10, recall that cards are labeled in base 10 so Munroe's math is wrong to start with.
- imglorp 8y agoYeah I did. Fixed.
