What To Look For In A Computer Hard Drive
By: Cedric H. Dirose
There is no doubt that the computer hard drive is the lifeblood of any computer, from the tiniest laptop to the largest computer server. Without a hard drive on which to store data, even the most technologically advanced computer is worthless, so it is important to choose that drive carefully.
These days, of course, there are computer hard drives in far more than computers. In fact, those hot new iPods actually sport hard drives with a higher storage capacity than all but the most powerful computers on the market a mere decade ago. It is hard to believe that the technology behind computer storage has come so far so fast, but in fact prices have dropped nearly as fast as storage capacities have increased.
This is of course good news for the computer shopper, and this means that shoppers are able to get much more bang for their buck than would have been possible only a few years ago. These days the storage capacity of a computer hard drive is likely lo be measured in hundreds of gigabytes, providing plenty of storage for music, movies, photographs and other valuable documents.
The type of hard drive you need will of course depend on the type of computer equipment you are shopping for. If you need hard drives for a computer server, you will likely be looking for a hot swappable SCSI (small computer serial interface) hard drive with a fast seek time and a high degree of reliability. The beauty of these drives is that they can be replaced even while the server is running, and in most cases the end users will never know that anything has happened. This makes it easy to quickly replace and rebuild a failed drive, and SCSI drives are the industry standard for web servers and other high value servers.
Of course most of us will not be shopping for these more expensive server hard drives. In most cases, home users will be purchasing internal hard drives which use a simple IDE interface and are quite easy to install. The storage capacities of these internal hard drives varies quite widely, from a low of about 60 or 80 gigabytes to hard drives capable of holding 200, 300, 400 or even 500 gigabytes or more.
If you can afford a higher capacity hard drive it is best to buy it. No one has ever regretted buying a hard drive with too high a storage capacity, but if you buy a hard drive that is too small you will quickly regret it. If you fill up the computer hard drive that came with your computer you will have to either replace it with a larger capacity drive, buy a second internal hard drive or purchase an external hard drive that connects to the computer with a USB cable. It is better to shop for as large a hard drive as you can find, and this will be the most cost effective solution in the long run.
