Big Data is part of our lives and we create a lot of it. If fact, users globally generate 2.5 quintillion bytes of data every single day. Traditional hard drives (HDD) use spinning platters with mechanical moving parts and nonvolatile storage that retain your data even after the power is shut off. Solid-state drives (SSD) utilize integrated circuits, which can store large amounts of data that can be accessed very quickly. In this case, interconnected flash memory chips also retain the data after the power is shut off. Regardless of your storage medium of choice, you need to realize that your hard drive will always contains documents, emails, banking statements, and loads of personal information directly tied to you.
