The average spell seeker's English spelling is Average Seek Time, which is one of the most important parameters for understanding hard disk performance. It refers to the average time it takes for the hard disk to move from the beginning to the track where the data is located after receiving the system command. It reflects the ability of the hard disk to read data to some extent, and it is an important factor affecting the internal data transfer rate of the hard disk. Parameter in milliseconds (ms). The average seek time is different for different brands and models, but the lower the time, the better the product. The average seek time of current mainstream HDD products is around 9ms.
The average seek time is actually a parameter that is comprehensively determined by various factors such as the rotation speed and the capacity of a single disc. In general, the higher the rotational speed of the hard disk, the lower the average seek time; the larger the single-disk capacity, the lower the average seek time. When the capacity of a single disc increases, the seek and movement distances of the magnetic head are reduced, thereby reducing the average seek time and accelerating the speed of the hard disk. Of course, in terms of market positioning and noise control, manufacturers will also artificially adjust the average seek time of the hard disk.
The data on the hard disk is divided into tracks and stored in clusters. After frequent reading and writing operations, the data is not continuously arranged on the same track. Therefore, when the magnetic head reads data, it is often necessary to repeatedly move between the tracks. Therefore, the average seek Road time plays a very important role in data transmission. Average seek times also play a crucial role in reading and writing large numbers of small files. When reading and writing large files or storing large amounts of data, the advantages of average seek time are not reflected. At this time, the size, speed, and buffer of the single-disc capacity are more important factors.
