Simply put, a computer’s hard drive is a piece of technology that stores the operating system, applications, data, and files that the computer uses in regular operation. All files and folders are physically stored on a hard drive, and that is what your computer keeps using every time you get on to work or play.
Why is having a well-working hard drive so important even past accessing your files? Every time you do something that involves reading or writing data to a hard drive, you must do it on your hard drive.
On the market for a new computer and still a little lost?
How do you decide which hard drive to buy, or which computer to buy based on the built-in hard drive, falls down to a few factors. The first is how much does it cost? When looking at the hard drive specifications of a computer or notebook, there are two important considerations that factor into the price.
- The speed of the hard disk depends on how fast the spindle of the drive moves and the disk rotates. Think of it like a record player – as they are quite similar. This is the most common type found in mid-range laptops. If your hard drives are mechanical storage devices based on rotating disks, they are intended for a hard drive or SSD. A speed on the hard disk means that its spindles move at an average speed of 1,000 rpm or 1.5 miles per hour and its plates spin at 2,500 rpm. The downside is, that much like a record player arm, if the “needle” breaks off, you are going to find yourself unable to access your information.
- It is also very important to know the size of your hard drive, because if you run out at an inopportune moment, you’re going to have big trouble. In fact, you’re going to find yourself hard up until you clear some room. Again, mid-range desktop and laptop models usually come with storage capacity between 250GB and 500GB which may be fine for personal use, but business use will likely quickly fill up this storage capacity. Of course, smaller-capacity hard drives will come at a cheaper price.
Depending on the amount of data present, it can take a long time to complete a full system backup, making it so that in some cases, it may not be practical or even feasible to make a full backup of all data on a computer hard drive, even for the simplest collection of applications.
If you’re looking for replicability, should it die on you, you’ll likely want a desktop, “tower” computer. If you own a laptop and want to replace it, the process can be quite complicated, especially if you don’t know what you’re doing. Installing a new internal hard drive is a tedious process, and you need to open the laptop, find the small hard drive set, usually hidden amongst other components, carefully remove it, and reassemble. Probably something you’d rather just hire out to skilled labor!
If your computer dies for any reason other than a dead hard drive, you can convert your old drive into an external unit and retrieve all important files from the drive. However, if you’re really unlucky and the hard drive itself dies, you’re in for hard luck, as those files will likely be totally inaccessible – think of it like trying to get information out of a library that has burned down.
To wrap, when picking out a new computer or replacement hard drive, there are a series of factors to consider, all of which will contribute toward the purchase price – storage space, device style, device speed, and internal or external type.
