Computer hard drives – out of all of the important computer components, these are the most important for one of the most important uses of a computer – to store and read data. Computer hard drives determine what you can access on your computer. All of your applications. Your operating system itself, anything – games, media – are all stored on your hard drive. computer hard drives used to be new technology approximately ten years ago. However the technology has developed and the original hard drive evolved. An individual hard drive can now store up to 8 terabytes of data on each hard drive (essentially, 8TB hard drives can be sold to consumers now. Although these can be very expensive).
The speed of which a computer hard drive can write data is dependent on how fast it can read or write data. This is dependent on the amount of RPM, or revolutions per minute. The RPM determines how many times the computer hard drive can spin every minute. And the faster it is, the better it is.
For example. A computer hard drive with a speed of 7200 RPM spins much faster than a computer hard drive with 5400 RPM, and as such that computer hard drive is generally better since it is faster. And therefore handles data quicker.
As technology has progressed, there are also now several means of storage devices. There are internal and external hard drives (internal drives are installed into a computer or laptop. While an external hard drive can be connected via USB and remain outside). There is also the new technology of SSD’s. Or solid state drives this is a new form of a storage device. Which can read and write data a lot faster. As such it is more expensive in terms of its price per GB.
