Bonus: Basic Characteristics of External Hard Drive

External hard drives are used for massive storage of data for electronic devices. Hard drives are always characterized and rated on the configurations like data access performance, storage capacity and physical form factor.

1. The external hard drives are categorized as mega storage devices that store the data for device uses. Hard drives are not the source of active data storage for devices and computers. They are occasionally used to recall the data to the main memory of the device. The classification of hard drives was initially exclusive to platter hard drives; the flash memory is now emerging as a mega storage solution. These drives are always characterized on the tasks performed by it rather than how it performed.

2. The capacity of a hard drive is the main feature that makes it stand out from the crowd. The mega space in megabytes and gigabytes is categorized on the space it provides. The induction of flash-based hard drives in the modern market has grown to an extent that the price extinction started from thousands of dollars per megabyte to cents for a gigabyte. Although, the flash hard drives are costly as compared to the platter based hard drives irrespective of the capacity.

3. The classification of a hard drive is done on the basis of its data reading and writing speeds. In mechanical hard drives, how many times per second the internal disk rotates is used to classify. The raw speed of a device is not always followed to check the performance, connection type, storage mechanism, and device bandwidth is also a factor to determine the speed and capacity of a hard drive.

4. The amount of space and how it gets connected to the computer is also a key factor of the external hard drives. The connection standards for hard drives are SATA, SAS, PATA, and SCSI. These are some features of hard drives that your computer should be compatible with and if not it can be added with the help of expansion cards.
