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.

Have a Glimpse of Digital Data Series! For complete info on binary digits read the introduction to Binary Numbers underneath:

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

Few years back, the common problem pertaining to hard drive is to find the hard drive with capacity of 5MB, however, today; it is absolutely difficult to buy a new hard drive with capacity less than 40GB. These days, common capacity for hard 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.
