What is the native queue command?

The native command queue is a system that allows hard drives of serial advanced technologies (SATA) to control their own internal queue of reading and writing requirements. In systems that do not use native command queues, drive commands in the order they were received from the main system. The native command queue allows the unit to change the order order to make the search process more efficient. This accelerates the recovery time of information and reduces physical wear on the unit. Each unit has several plates, all contain information. For reading and writing on a plate, the shoulder uses a shoulder similar to the record player. When the plate rotates, the arm moves back and forth through the plates containing data. Two related information can be widely distributed on the unit. Reading pieces, the arm finds the first and then moves in the position to locate the second. If the unit receives one command to read or write after another, the arms will have to move constantly to get ZaroNala with data. If each of the commands requires the arms to move to the opposite side of the same plate, a lot of time will be lost in the process.

By using the native command of the command, the unit can select the order in which it performs a set of commands. Basically, it performs as many operations as possible in one area and then moves to another area. This means that the drive has shortened the time of searching and waiting between commands. As another side advantage, the drive spends less time to create unnecessary movements. This reduces the wear of the drive by a small amount.

Advanced systems can take advantage of another advantage of native command in the queue. When the processor -fled and unable to accept commands, the unit can move all the entry requirements to the front of the queue. Since the processor is too busy to arrive reading commands, the unit may decide not to solve any. This may result in a huge improvementPower, especially in systems with multiple units and more cores.

This technology is also used on some forms of solid state discs. These units do not use standard drives with shoulder and pads, so they generally work much faster. Because they are so fast, they will often work faster than the rest of the system and eventually end closely. Using the native queue command can change the order of their commands and send reading whenever possible, and write when the system lags behind.
