Top Hard Drive Manufacturers

Consider a Read more HDD hard drive device, and also get acquainted with the best manufacturers and their model.

Hard disk (also, storage device on rigid magnetic disks, Hard Disk Drive or HDD) - Storage device, which is necessary For storing files and various data. Without such a disk or other type drive (for example, SSD, which will be talked next) the modern computer will not work. Simply, there is nowhere to install the operating system.

Why a hard disk is va Light

As we have already found out, the computer is vital of any drive to store the operating system files and its main components. For a computer, it is not so much that the presence of HDD is not at least any drive. Under the drive can also be implied and another type - SSD solid-state discs.

The rigid drive consists of a special magnetic disk (aluminum or glass plate coated with a layer of ferromagnet) and the magnetic head, which, when rotating the disk, writes or reads Information on it. There are many ways to write information for which HDD is divided.

The longitudinal entry

of the first data recording technology was CMR. In hard drives with the CMR method, the following model was used: a magnetic head, passing over the surface of the rotating magnetic plate, magnetifies billions of separated areas (domains).

With this approach, the magnetization vector of each discrete disk sector was directed horizontally - in the direction of the surface of the plate itself. By 2010, CMR technology was completely outpaced from the market due to the fact that it provided a small record density, which reached the maximum value of 23 Gbps.

perpendicular recording

This method, called PMR, was known for approximately the 1970s, but for unknown reasons was not used and was safe Forgotten.

In hard drives with PMR records, domains (discrete areas in which information record occurs) are not horizontally, as in the case of CMR, and vertically. This allows you to reduce the plate area necessary to record 1 bit of information and, accordingly, significantly increase density. Simply put, the "long" domains now occupied a much smaller square. For this reason, on the same site of space in the case of CMR technology, it was possible to place more cells on the disk.

HDD with technology PMR began to appear in the market approximately since 2006. This was contributed by the fact that the previously used method of recording CMR had a sufficiently low ceiling in the form of a maximum record density in 23 Gb / cm². Hard disks with PMR recording are actively used now, and the theoretical density limit of this method is more than 1 Tbit / inch.

Tiled Magnetic Record

SMR technology - Shingled Magnetic Recording began to be applied in disks since 2010. To understand the essence of this method, you need to trace a small tendency.

After the transition from the technology of longitudinal recording to perpendicular, each discrete region (domain) on the plate began to take less space on the disk. It was necessary to increase the record density and, ultimately, to create more capacious hard drives. Within the framework of existing technologies, it is impossible to reduce the areas even more, so a tiled method was developed, where the tracks on which the entry takes place is superimposed on each other.

SMR, in comparison with PMR, allows you to raise the density again and make more capacious hard drives. But at the same time, the method has a big drawback, especially concerning custom computers and systems for which the maximum performance is important - low recording speed / overwriting.

Western Digital

The first few hard drives will be from the Western Digital brand, founded in 1970. They are distinguished by increased reliability and quality, as well as not the most affordable price. But for everything you need to pay, including the game hard drives from a special line, which is present in the model range of the manufacturer.

The second hard disk from WD - WD10PURZ. This is a more universal model, compared with the previous one. It is ideal for home use, since the drive has a standard memory for today's memory in 1000 GB, a low noise level of 22 dB and sufficiently high speed indicators and read / write data.

And thanks to the absence of overheating, as well as stable and silent round-the-clock operation, the model is also perfect for various surveillance systems.

Western Digital WD5000AZLX

  • Size: 3.5 inch
  • Vault Volume: 500 GB
  • Connection method: SATA 6 GB / S
  • noise level when working: 30 dB

The last HDD in the WD rating is a WD5000AZLX model. Excellent output if the previous discs would be great for you, but too hit the pocket. This hard drive also, as well as the two previous, is distinguished by low noise, speed, stable and uninterrupted operation. Capacity is not the most impressive, but for a home computer is quite a good indicator.

Seagate

Another American company that is based on the production of rigid drives. It was founded in 1979 and for quite a long period of its existence felt both ups and downs.

by tradition Let's go from expensive HDD to budget. And it will open the top three winchesters at Seagate model from the Skyhawk line with this long name. According to the development of the developer, the working time of the hard drive on failure is 1 million hours, which means more than 116 years of work in the round-the-clock mode.

Hard disk has an impressive capacity of 6000 GB, which means that it will fit on it if not all, then almost everything. It is perfect for various video surveillance systems, as it is simply not a reasonable option as a home use. In addition to the case, if you find than to occupy the entire capacity of the drive.
