SSD pays attention to the principle of “less partition”. One is to consider the problem of reserved space. In addition, too many partitions of small capacity SSD are easy to cause partition dislocation, and the performance of SSD in the disk area at the partition boundary may be affected.
From the era of mechanical hard disk, friends tend to divide the hard disk into multiple partitions, and then set their own purposes for different partitions through volume labels. Nowadays, the solid-state hard disk gradually replaces the traditional mechanical hard disk, and has become the first choice for installation.
一般来说，固态硬盘讲究的是“少分区”的原则，一是考虑到预留空间问题，另外小容量 SSD 分区太多容易导致分区错位，在分区边界的磁盘区域 SSD 性能可能受到影响。
Generally speaking, SSDs pay attention to the principle of “less partitions”. One is to consider the problem of reserved space. In addition, too many partitions of small capacity SSDs are easy to cause partition dislocation, and the performance of SSDs in the disk area at the partition boundary may be affected.
Solid state drive vs. mechanical drive
Although partition does not affect the read-write performance of SSDs, it will reserve a part of spare space for each partition after partition, and the reserve of spare space will cause capacity waste. If a partition is used more than 90% for a long time, the garbage collection mechanism will be affected and the possibility of SSD crash will be greatly increased.
In general, no zoning has the advantage of no zoning, while zoning has the risk of zoning. However, I think if the capacity of the SSD is large, it can be divided into different areas. After all, if the system crashes and is poisoned, reinstalling the system will not result in the loss of data from other disks.
