Is the bigger the default value of Win10 allocation unit size, the better?

　Is the larger the default value of Win10 allocation unit size, the better? Now more and more people are using the Win10 system, but we always have various problems during the use process. For example, some friends encountered the allocation unit size when formatting the U disk. question, so what's going on? Let's follow the editor to see how to make the default value of the allocation unit size larger.

The larger the default value of the allocation unit size is, the better the method is. Generally speaking, the larger the allocation unit size, the better and the faster it will run, but it will also waste space. , so generally a moderate one is fine, and the default value is also appropriate.

When formatting a U disk, the choice of allocation unit size is not that the bigger the better, but an appropriate intermediate value. Generally speaking, the default value is enough. This item should not be adjusted unless there are special needs. value.

The allocation unit during formatting refers to the size of the cluster. A cluster is the smallest unit in which a file system stores files. A file will occupy at least one cluster. For example, if the selected cluster size is 4096 bytes, then even if the file to be stored is only 200 bytes in size, it will occupy a cluster on the hard disk, which is 4096 bytes of storage space.

It can be seen that if the cluster size is set too large, a large amount of disk space will be unused and wasted disk space; if it is set too small, it will cause the cluster on the hard disk to be damaged. If the number is too large, the hard disk will waste a lot of time seeking and the performance will be reduced. Therefore, its value should take into account the needs of space and performance, and generally the default value is sufficient.

Allocation unit, formerly known as cluster. It is the space size divided by the operating system for each unit address. For example, if a building is divided into several rooms, each room is the same size, and each room is given a room number. At this time, each room The size is the allocation unit. When creating a partition, the option of allocation unit size will appear.

The more blocks a file is divided into, especially when these storage units are scattered, it will waste some time when just reading the data. You can imagine that the magnetic head is struggling to read the data bit by bit on the disk. Time is wasted when moving.
