The external hard disk drive is the form of the internal hard drive and can be connected to the computer system through the data (external) cables. Auxiliary power is required by some of the external hard drives and the other drives get the power from the USB 2.0 data connection. The external hard drives provide the facility to the users as an excellent backup hardware due to its portability and the capabilities of data storage. The external USB drives also have different sizes and shapes like the internal hard drives.
The most typical type of connection for the external hard drives is the USB 2.0 (universal serial bus). The external drives also have the SATA and the Firewire connections.
The customer must be aware of his computer’s capabilities and requirements before selecting the external drive. The Firewire drive requires Firewire connections and therefore, the user will have to buy the additional hardware (Firewire connections) to operate the drive. Basically there are 2 camps of the users of external drives. One of them is those who connect the drive permanently and the second one is those who connect the drive only when they are backing up the data.
The users who connect the external drive permanently to the system utilize the drive as RAID-1 configuration or a mirror. Most often the included software in the external drive allows the customers to do this, but sometimes the user has to use the software of third party. This method is easy and advantageous as the customer gets backups (real time). And the disadvantage of this method is that the external drive runs constantly and is attached constantly to the system. Other mentality of the users of external drive is they connect the drive to backup data or photos. This method requires backup schedule because the backups may become nearly useless or quickly out of data. In this method, the user has advantage that he can store the external drive in a secure location off site from the computer. While the disadvantage of this method is that the data backups may not be up to data completely on any of the given day.
The external hard drives are portable, reliable and are fairly cheap. Their life expectancy is almost the same as that of the internal hard drives possibly if the external hard drives are not constantly connected to the computer. External hard drive’s most important benefit is that it can be separated from the system and can be stored any where else. The backup data in the external drive can be kept even safer by keeping the drive in off site location or in safe (fireproof). If the external drive remains connected to the system all the time, then it will be exposed to same threats as that of the computer like theft, fire etc. The external hard drives are vulnerable to be accidentally dropped or shock. External drives provide great solutions for data backup. The most important facility of the external drives is that they can be separated from the system between backups.
