All computer data are stored in the internal hard drive. Hence, you may wonder if performing many operations at the same time would be harmful to the drive. In this article, we will probe into this issue.
At times, inevitably, you may need to undertake multiple tasks on your computer at the same time. For instance, you are dealing with some files – Word documents or Excel workbooks, and meanwhile, in the background, the internet browser is downloading files, the system is installing new programs and so on. In this case, your computer will swap data from RAM to hard drive. That is to say, hard drive is no longer a simple repository of data, but also needs to support PC working. In this situation, your hard drive would be at risk and become more vulnerable. But, in general, as long as you keep patient and handle it with care, drive will not be damaged.
Every computer has its own limited speed of file transfer. To be specific, if your computer is close to that limit, you will discover that the PC works pretty slowly. Such cases can happen when you try to transfer a great amount of files in the meantime. However, to be honest, nowadays, majority of modern hard drives are so fast enough to avoid exceeding the speed limit. Hence, generally, the excessive file transfer will not harm the modern and new drive. But, if your drive is aged, it will.
When you save a file to a hard drive, the drive will split the file into multiple file pieces and spread them to the available free space on the drive. This is called file fragmentation. Under this circumstance, if you just save a small number of files to a hard drive simultaneously, nothing will occur. Nevertheless, if you store multiple files to the drive at the same time, it’ll be quite slow. And in this course, hard drive is vulnerable.
Files are scattered randomly around the hard drive. Hence, when you attempt to read a file, the drive heads will need to jump from one location to another inside the drive. Thereby, if your drive data is scattered widely, when you try to open and read a lot of files at once, the heads have to work wildly and even crash at times. As we all know, head crash could cause data corruption like corrupt PST file and would exacerbate wear and tear of drive, so it is harmful to drive itself. Fortunately, most hard drive today comes with command queuing feature, which can organize the files in order.
