How Are Mass Storage Devices Used & Controlled?

SD Card and Card Reader

Let's face it: computers have become an integral part of our lives. But while terms like email and Internet are things you hear almost every day, you might be surprised to find that you probably already know what a mass storage device is, and you likely use a few of them every day.

What is a Mass Storage Device?

Internal hard drives are commonly used for data storage.

A mass storage device is used for storing a large amount of computer-readable data, such as digital photos and music, in such a way that the device doesn't need a constant source of power to "remember" its contents. Since this term has been around for awhile, it includes even severely outdated floppy disks--many of which could hold less than one present-day photograph--under its umbrella of large data storage.

Common Types

USB flash Drive hold a great deal of data and are easy to use when traveling.

As of March 2010, the most commonly used mass storage devices are USB flash drives, MP3 players, internal and external hard drives, DVDs, CDs, Blu-ray discs and SD cards.

Common Uses

Mass storage devices are often used in cameras and cellphones, in the form of SD cards, in order to store pictures, music and video. They are also a convenient way to transport files from one computer to another in the form of a USB flash memory stick.

Using mass storage devices

In order to use a mass storage device, you need to connect it your computer or other compatible device, such as a camera. Certain mass storage devices, such as internal hard drives, are built into most computers and are almost always connected. If they weren't connected, your computer wouldn't be able to do much more than turn on. Other storage devices require that you connect them through a USB port or an SD card slot. Consult your product manual to find out which is appropriate for your device. Most computers and laptops built in the last few years come with both USB ports and SD card readers.

Accessing a Connected Mass Storage Device

Some USB devices come with software to help you access their contents, but if you don't know which software came with the device, the best way to access your stored data is to navigate to it directly through your operating system. Using Microsoft Windows XP or later, click the "Start," then click "My Computer" or "Computer" from the options on the right side of the window. A list with your available drives will show. Insert the mass storage device you would like to access and then double-click on the new device that appears in the window. Drag and drop files to and from the drive as needed.

On a Mac, all available drives are shown on your desktop automatically, so when you insert the drive that you would like to use, double-click it once it appears on your desktop to access it.
