HDD hard disks are magnetic storage devices with large internal memory and sufficient writing and reading speeds at relatively affordable prices. The history of hard disk drives begins in the mid-fifties of the last century, when the first prototypes of magnetic hard disks were created, possessing tiny volumes and huge sizes by today’s standards.
Below, we will consider the main criteria for choosing modern hard disks, tell you what you should pay attention to when buying a hard drive, and give the main distinguishing characteristics of hard disks.
Most Popular Types
You should pay attention to one of the leading indicators – the type of device. Hard disks are divided into the following types:
- HDD: Magnetic plates are used to record information. It is necessary to consider the sensitivity of such disks to mechanical damage.
- SSD: This type of storage device uses solid-state memory. The same connectors and connection sizes characterize it as HDDs. During operation, the SSD disk does not produce noise, consumes little electrical energy, and transfers data quickly. Such a device can withstand shocks. The only drawback is the limited number of write cycles.
- SSHD: This hybrid drive combines the best qualities of HDD and SDD. It transfers the most frequently requested information, presented as a hard disk equipped with a small-capacity solid-state drive. A hybrid drive has all the advantages of an HDD, but data is transferred faster. The drive is perfect for tasks that don’t require high performance. It is an ideal choice for a laptop.
RS stands out in the market by offering a diverse range of hard drives, providing users with reliable storage solutions tailored to their specific needs.
The Combination Of HDD And SDD
The combination of HDD and SDD is popular in home computers. The former is used to store data, and the latter is used to install the system. This combination allows you to make the system as fast as possible and increase the amount of data that can be stored.
When choosing a disk array or a network-attached storage device, consider the number of bays available for installing HDDs. This characteristic is necessary to determine the total capacity of the device. The number of bays can be from one to ten or more. To perform backup and archive information, use a streamer, the principle of which resembles a cassette recorder.
Hard Drives Classification According To Their Function
Hard drives are divided into different classes. The division depends on their purpose:
- Personal computers: HDDs and SDDs with a width of 3.5″ are used for equipment. Server drives with a 2.5″ or 3.5″ width are reliable and fast. However, it would help if you remember that they emit quite a lot of noise during operation.
- Laptops: A distinctive feature is the low noise level and small amount of heat generated during operation. SSDs are often used to equip laptops.
External hard drives are used as additional storage devices. They are presented as a disk with a 3.5 and 2.5 inches width. A unique controller is used to connect to the required port. There are mobile and stationary external drives. In the first case, the device is similar to a flash drive, with a USB port for connection.
However, a mobile external drive is much faster and has a larger capacity. Stationary devices have a power supply and must be connected to a standard one. Their capacity is larger than that of mobile versions and looks more massive. They can make noise during operation.
The Bottom Line
Selecting a reliable hard disk involves considering various factors to meet specific needs and preferences. The evolution of hard disk drives from the bulky prototypes of the mid-fifties to today’s sleek and efficient devices offers a range of options for users.
