External hard drive


An external hard drive is a type of hard disk drive which is externally connected to a computer, and may be portable. External hard disk drives are connected to the computer using a cable which is compatible with Small Computer System Interface (SCSI), Integrated Drive Electronics (IDE), Universal Serial Bus (USB), IEEE 1394 (Firewire), CAT-3 or CAT-5 cable (Ethernet), eSATA or other bus standards.[1]

History
Main article: History of hard disk drives
The first commercial hard disks were large and cumbersome, and were not stored within the computer itself so therefore fits within the definition external hard disk. The hard disk platters are stored within protective covers or memory units, which sits outside. These hard disks were soon evolved to be compact enough that the disks were able to be mounted into bays inside a computer.
By the end of 20th century, internal drives became the system of choice for computers running Windows, while external hard drives remained popular for much longer on the Apple Macintosh and other platforms. Every Mac made between 1986 and 1998 has a SCSI port on the back, making external expansion easy; also, "toaster" Macs did not have easily accessible hard drive bays (or, in the case of the Mac Plus, any hard drive bay at all), so on those models, external SCSI disks were the only reasonable option. These external drives, like the Apple ProFile are in no way as portable nor as compact as the modern ones for commercial use.[2] [3] [4]
After the Internet has been introduced, more information and files needs to be stored than ever before, and more back-ups be made due to threats such as viruses. Once again, external hard drives are popular among users of all platforms.[5]
Presently, the market for external hard disks are aimed towards portability, as well as a higher amount of memory. Currently the commercial external hard disks of the highest capacity are usually found at 1 TB or 1.5 TB from manufacturers such as Hitachi, SimpleTech, Western Digital, Seagate, CMS, RecoNdata, Maxtor and LaCie



The internal structure of external hard disk drives is similar to normal hard disk drives; in fact, they include a normal hard disk drive which is mounted on a disk enclosure. [5] For the same reason, high capacity external hard disk drives (which weigh more) were for a time less common, although external hard disk drives with more than 500 GB of storage capacity are now commonly manufactured.
Although
external hard disk drives are aimed to be portable, the data cannot be secured on them due to their insufficient shock protection [6] especially compared to digital portable media storage devices such flash memories and memory cards. Nonetheless, external hard disk drives cost less than memory cards or flash memories of the same storage, and are the only portable media storage options available in the size of hundreds of gigabytes.
