How Heavy Is a Petabyte?
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?"
Yes, you can get 1 Petabyte server with only 20 storage servers now. These are available now.
Here is the spec. You would need only 20 units for 1 Petabyte. Thanks for reading!

The creation of information is not reversible. Thought requires the use of energy. So does any process by which data is stored. Then, energy is required to maintain the data and information, and energy is required to remove the information. If the process of information creation were truly reversible, then it would evolve energy in the process.
Consider writing, which is one of the most reliable ways to store information. Composing something meaningful evolves heat because the person writing had to move a utensil across a page. Erasing this information also evolves heat because it requires the destruction of the pattern through some process of motion.
SRSLY.
