Data storage is a crucial part for any business, without it the consequences could be hazardous. Data storage enables businesses to store data for various reasons such as reference, records and recovery. There are many ways in which to store your important business data. As well as keeping hold of important data, data storage manages and filter the useful from the useless and gain more space.
Data storage can come under the following categories:
Primary Storage
Often referred to simply as memory, it is directly accessible to the CPU and read instructions stored there, executing them as required. It is the main source of storage used.
Secondary Storage
This is external memory like hard disk drives and is not directly accessible by the CPU, like Primary Storage. Some examples of secondary storage can include; USB flash drives, floppy disks, punched cards, and CDs.
Tertiary Storage
Typically this storage involves a robotic mechanism which will mount (insert) and dismount removable mass storage media into a storage device according to the systems demands. This data is often copied to secondary storage before usage. Tertiary storage devices are commonly used for archived data and data that do not get used often.
Off-line Storage
Like it states, off-line storage is physically disconnected and removed from computer systems. This storage has to be inserted or connected by a human operator before a computer can access it again. It cannot be accessed without human interaction.
Cloud Storage
This is a new form of storage, involving storing information on multiple virtual servers, generally hosted by third parties. Hosting companies tend to be using cloud storage more and more, because customers themselves can store files or data objects.
So there you have it. The methods of data storage are varied and many. Depending on what type of data storage you are looking for with your business, most data storage devices are easy to use and inexpensive. Data storage can save your business space and can make your systems run faster; making it easier to locate and save archives data.
