Size Matters
It’s a digital world out there, and the key to our survival, in my opinion, is not processing power. It’s data storage. Once all the numbers have been crunched, all the images have been gathered, and all the test results have been compiled, you need to store them somewhere. Somewhere safe, because unlike former means of recording...
