Choosing From the Different Types of Data Storage and Backup Devices

Author: Administrator
Our fast-paced, ever-changing modern world pushes us to keep up with these demanding times. Every day, we work with important, confidential or critical information for our personal and professional success. A single detail lost can cause a huge impact or damage your business. Let's face it; it's costly to lose information. Thankfully data storage devices are becoming more affordable and efficient every day.

When it comes to recording or duplicating electronic or computer data, there's an array of media available for data storage or data backup. To choose the best storage or backup device, you have to take note of its purpose and features. Different devices are good for different reasons; each has its pros and cons. There are removable or portable, permanent and rewritable storage devices, depending on what you need.

Different Types Data Storage Devices

Here, we categorise the types of each data storage device to find out which devices are suited for your different personal and professional storage needs.


-Storage drives that are physically part of or are connected to the computer or network server for additional memory space or capacity
-Data can be accessed once the computer, where it's connected, is turned on
-Disadvantage: data is corrupted or lost if computer is damaged, not backed-up or virus-attacked


-Portable storage devices that can easily be connected to or removed from the computer
-Data can be accessed in any computer that has an appropriate drive which can read the portable storage devices
-Disadvantage: portable devices can easily get lost, damaged or misplaced


-Data are virtually stored away in a server or computer at a distant location
-Data can be accessed in any computer by connecting to the network, server or Internet
-Disadvantage: takes time to access data and is less secure
