It is all normal for an individual and a business to slowly and over time accumulate data and medium on a computer and on a network as well. Data and media take up a lot of resources in the computer and in the network in the case of a business. This necessitates that an alternative storage is found and that resources are freed up and channeled to important and pressing concerns whether it is at the individual level or for the business. This is where the need for and the importance of the external hard drives will be appreciated.
Content, media and any other form of data should not just be left on the computer without being backed up. There are several reasons why this should be done and they all stand important in the protection and the perpetuation of the data. Storing this data on the external hard drives also frees up the computer allowing it to work faster and more efficiently. But the most important and the main reason why data is to be stored is make sure in the event that a hard disk will crash and any other unfortunate scenario is to take place, then the data remains safe and intact. These unfortunate and often catastrophic events cannot be entirely avoided nor predicted, therefore storage and backing up data becomes a necessity and never a choice.
The external hard drives can be classified in various different classes and this is dependent on various features and the technology used in the manufacture of the drives. There are the hard disk drives which have been the conventional external storage. The hard disk drives are further classified into two and we get the portable drives and the desktop drives. The portable drives when compared to the desktop drives are small and do not required an external source of power. This is the chief reason behind the name portable since this is a hard drive which you will carry around with you in the pocket or with laptop in its bag. The portable hard drive is simply plugged to a laptop or the desktop computer through a USB cable and the devices is ready for use. They become very good for carrying files around and for the music and movie collectors they become a very good ally. And for the storage of information the portable hard drive also becomes a very good choice in doing a back up. The other main advantage is that the majority of the portable hard drives come with backup software which when once installed will give the great feature of automatic backups which can be scheduled to the preference of an individual.
The desktop hard drive is the other type of the hard disk drives and these are larger in size in comparison to the portable drives. The desktop drive requires an external source of power so that it is functional. These hard drives are far much superior in function owing to the large capacities that they are able to provide. They distinctively offer up to 2TB of memory which is just what a business may require as storage capacity for its data now and in the future. Other advantages with the desktop drives are that they have greater rotational speeds and hence make the transfer and retrieval of data become faster. Just like with the portable drive, automatic backup can be scheduled.
A second major category of the external hard drives is the solid state drives (SSDs) which carry greater advantages since they are extremely fast and far much durable. This is because they contain no moving parts which make them safer. The SSDs also provide greater capacity offering up to three times more capacity than the hard disk drives.
Aside from the classes and the sub types of the external hard drive storage, when choosing the external hard drive to purchase and use for the storage of data be sure to know the size or capacity required for storage. The security to go along with storing or backing up the information is another factor and lastly the speeds which are provided by the drives. The most common drives will use the USB 2.0, USB 3.0, eSATA and the FireWire connectors.
Make your choice now and store all files and information since it is cheaper and time saving to backup data than to retrieve it once lost.
