What is the best type of data storage?

Data can be accessed faster from an external hard drive than from a magnetic tape. But if you’re on a budget, the best bang for your buck is going to be magnetic tape. CDs, DVDs and flash drives are better if you need to access the data a bit more often, and don’t have as much data to store.

What is data storage capacity?

Storage capacity refers to how much disk space one or more storage devices provides. It measures how much data a computer system may contain. For an example, a computer with a 500GB hard drive has a storage capacity of 500 gigabytes. A network server with four 1TB drives, has a storage capacity of 4 terabytes.

What type of storage is a HDD?
