Learning About Hard Drive Capacities


Different Storage Capacities of Hard Drive: Hard Drive has different storage capacities, which is measured in Bytes, Megabytes and Gigabytes. In order to understand these figures properly first thing you are required to know is that you must acquire basic knowledge of how data is stored or processed in digital systems like PC's.

  • 1Bit = either a 0 (zero) or a 1 (one)
  • 1Byte = 8 bits
  • 1KB (Kilobyte) = 1024 bytes (210)
  • 1MB (Megabyte) = 1024 Kilobytes (220)
  • 1GB (Gigabyte) = 1024 Megabytes (230)
  • 1TB (Terabyte) = 1024 Gigabytes (240)

Fewyears back, the common problem pertaining to hard drive is to find the harddrive with capacity of 5MB, however, today; it is absolutely difficult to buy anew hard drive with capacity less than 40GB. These days, common capacity forhard drive begins from 40GB up to and goes beyond 120GB.

For Better Understanding, Go Through This Example: This can be clearer with the help of an example, for instance, a photo holds 500 Kilobytes of storage space on a hard drive. Now, suppose you have 40GB hard drive, it is possible for you to store up to 81,290 color photos. It concludes that on your hard drive, you would need your Operating System and programs, which would take up some of the storage space. Here, it is crucial to point out that when you consider that an average letter written in a word processor is around 30KB, it becomes obvious that the storage capacity of modern hard drives is large.

Hard drives can store a very large amount of data in it that you can use again and again. Some times due to virus attacks, hardware failure, power outage, sudden system shutdown, your hard drive gets corrupted and data is lost. Certainly you need a data recovery program to restore the lost data from hard drive. Software gives you proficient data recovery software to recover all your deleted data from hard drive.
