How Heavy Is a Petabyte?

Posted by timothy on from the but-electrons-don't-weigh-anything dept.

Jon Morgan writes "Whilst heaving around numerous data storage systems to sell (they weigh A LOT!), we got to wondering: How heavy is a Petabyte of data storage? Our best guess is 365KG, which is 6 million times lighter than in 1980! But is there a lighter way to store a Petabyte?"

  1. Try using Micro SD cards instead by kroyd · · Score: 5, Insightful
    With 32gb cards weighting 0.5 grams one terabyte should require 32 cards, or 16 grams. 1024 terabytes should then weight 16384 grams, or a bit more than 16kg.

    I don't think there is a storage media with higher density available commercially right now - and probably not until the 64GB microsd cards becomes available.

    See, this is why I love slashdot. Ask a silly question and more often than not you'll get an answer.
