Computer technology is developing incredibly fast, and we do not want to lag behind them. That's why many of PC users decide to change one of the most important components - hard disk, or HDD. It stores not only your personal data (photos, favorite movies, music, documents, etc.), but also installed programs, drivers of connected devices, all files of the operating system. That is why when buying it, you need to stop your choice on a reliable component, in order not to lose valuable information in the future. But the modern market offers such a wide choice that it's time to get lost, especially for beginners. So, we'll show you how to choose a hard disk. By the way, in the purchase of this component, its technical characteristics are important. We will consider them.
Specifications
- Hard Drive Capacity. This is one of the main parameters based on which hard drive to choose. Volume means the amount of information that will fit on the HDD. Typically, the amount of media is measured in gigabytes and even terabytes, for example, 500 GB, 1 TB, 1.5 TB. The choice depends on how much information you are going to store on your PC.
- The hard disk buffer (cache). In the choice of a hard disk, the memory in which the data read from the disk is stored but transmitted through the interface is equally important. The maximum amount of such memory is 64 MB.
- Type of connector or interface of the hard drive. Thinking about how to choose a good hard drive, pay attention to the type of connector. The matter is that the hard disk needs to be connected to the motherboard. This is done using a cable. These cables come in different types - connectors or interfaces. In older computers, the so-called IDE is also used, which is a parallel interface with a wired loop and a power cable. In another way, this interface is called PATA - Parallel ATA. But it is replaced by a more modern interface - SATA (Serial ATA), that is, a serial connector. It has several variations - SATA I, SATA II and SATA III.
- The speed of rotation of magnetic disks determines the speed of the hard disk. The higher it is, the more easily, the faster it works
HDD. The optimum speed is 7200 rpm. - The size of the hard drive. The size of the hard drive implies a width that is suitable for fastenings in the computer. In a standard PC, a 3.5-inch HDD is installed. When choosing a hard drive for a laptop, they usually stop on thinner models - 1.8 and 2.5 inches.
