The Effectiveness Of The External Storage Hardrive

June 20, 2010 · Filed Under Computers and Technology by Daron Matochen·

External hard drives, also known as external hard disks, are linked to a computer by a USB cable. They are used for extra storage capacity, which can be anywhere from 160 GB to 4 TB. The Laptop or Personal Computer comes with an internal hard drive, but sometimes this does not have the capacity to store the amount of data, media and applications that are available today. This is why you would need external hard drives.

History: The very first external hard drives were big and unwieldy to handle, and because they did not fit inside the computer, they were called external hard drives. As technology progressed, external hard drives became small enough to be mounted into a bay, inside the computer. The first Apple Mac’s had very difficult-to-access hard drive bays that could not even take the normal internal hard drive, so they came out with external hard drives, this being their only option and their only hard drive.

Apple Mac plus other workstations stayed with their choice of external hard drives because they were reliant on the SCSI ports on these external hard drives. As USB and Firewire interfaces were being used by PC’s, the consumer saw more of the external hard drives. As the SCSI interface was both pricey and complex, it was replaced by the new Firewire and USB interface, leading to the standardization of, and lower costs in, the external hard drive market.

Internal Structure/Design: External hard drives are mounted in a disk enclosure, this being the firm outer case of the drive. The actual drive inside is exactly like the internal hard drive, but the external hard drive is less protected and more prone to being dropped, which could damage the moving heads and platters inside.

Internal Structure/Design: Although the external hard drive is encased in a tough and durable outer, the inside hard drive has precisely the same parts as the internal hard drive in computers, the moving heads and platters. This leaves the external hard drives more prone to accidents, but with proper care that can be avoided.

In 1987 Seagate brought out a 10 MB (Yes, that is 10 Megabytes!) hard drive. The largest capacity at the time was 30 or 40 MB hard drives. The computer industry was still in its infancy, so this demonstrates how far the industry has now come to be able offer a 4 Terabyte hard drive.

Compatibility: Most of the operating systems used today are compatible with external hard drives that support the relevant interface standards, which all servers, operating systems and embedded devices support. All operating systems developed before 2000 are obsolete and would need new drivers and upgrades to use external hard drives made after 2000.
