HDD Speed

Posted on by admin

Transfer rate is of two kinds: the interface transfer rate and transfer rate media. Transmission speed of the interface – the maximum theoretically achievable data rate of a hard drive from its buffer to the system. Media transfer rate measures how fast data can be moved to the media or with him. The rate of placing on the carrier (ie, write, Write Speed), as a rule, does not equal the speed of obtaining from him (read, Read Speed), and therefore usually separately specified recording speed and reading speed. The higher speed data – the better. Buffer. Another important criterion is the size of the buffer. The buffer (otherwise referred to as cache memory) stores data that are accessed most frequently or data that may be needed user to the next time.

Input / output data from the buffer occurs very quickly, data is transmitted to the system with a maximum interface speed. Thus, the larger the buffer, the greater the volume necessary information is stored in it, the faster the hard drive itself. Hard disk rotational speed. No less important parameter is the rotation speed is the number of spindle revolutions per minute. On this parameter in depend largely on access time and transfer rate. For external hard drives can be found at two speeds: 5400 and 7200 rev / min. Than at higher speeds – the more comfortable and faster to work with the hard drive. Interface.

External hard disk consists of a container for the HDD, which is placed inside the hard drive. Container and connect the hard drive interface, which is called internal. To replace the outdated IDE interface came SATA interface. External HDD drives with IDE interface is almost impossible to find on sale, but they do not, and practical necessity. Thus, most external hard drives have an internal SATA interface. As for the external interface, for the vast majority of external hard drives is USB 2.0.

Artesian Water Delivery

Delivery of artesian water. g.Vladimir. The pure water at the lowest price (only 50 rubles. For 19 liter bottle). Several decades ago we did not give importance to what air we breathe, what water we drink. We just breathed and drank from the tap and happy life. Life as always has its own changes.

Each of us knows that he must drink 8 to 10 glasses of water each day. But what does this leave us? And what are the rules for drinking water must be observed? Let us examine at first – that is water? Recall a time when we were at school in chemistry lessons. How does the formula for water? H2O. This compound of two gases that exist, however, as a liquid at room temperature, due to the molecular structure and internal links. The strength of internal connections prevents the separation of molecules into ions, so that pure water contains a very small number of ions, and has weak conductive properties.

It is able to maintain their properties and structure, even in tough environmental conditions. Water can be frozen at low temperatures or heated to a vapor state extremely high temperatures, while retaining its molecular structure. Drinking water for humans. Water for the human body – the second most important matter after oxygen. It is common knowledge that our bodies are composed almost two-thirds of the water. It is no accident people can live without food for more than 4 weeks and without water – no more than 7 days. Many scientists think that providing the body with water quality and quantity necessary for normal metabolic process, is the secret of renewal of youth. Daily need for water is determined by environmental conditions, as well as the nature of work. Under normal circumstances, to maintain the water balance need daily use of 2-3 liters of fluid.
