ram ddr4 vs SSD

ram ddr4 & SSD

external hard disk SSD OEM ram ddr4 Chinese a long-standing view on the Internet: SSD hard disk cannot partition.

the rationale can be summarized as follows: SSD exists read-write equalization algorithmram ddr4,” Partitioning will cause a portion of storage space to be excluded from read-write equalization ram ddr4, which reduces SSD lifetime.

but recently when tossing a dual system I wondered why all the discussions on the dual system have not talked about the problem of “partition performance reduction”? Obviously you can’t install a dual system without partitioning (WSL does not count)

so I searched and found the following post:

which has a detailed explanation, as well as some corresponding more specific information, interested students can click into it themselves.

for students who are too lazy to read the original text, I will summarize the views roughly:

1, partitioning does not have any effect on the SSD, because the SSD isolates the physical location, the operating system does not know the physical location of the file at all, as long as you read and write the file, its distribution may change randomly. Therefore, there is no such thing as “the separated area will not be manipulated”. Partitioning is just an “illusion” of the operating system, and you can even deliberately leave an unpartitioned space when partitioning, which can extend the life of the SSD.

2, the operating system did not adapt well to the SSD when it was first introduced. A typical problem is that it doesn’t align correctly, causing problems such as accessing a storage space that may span two physical segments. However, this problem does not exist in the latest operating systems today.

Of course, systems after win7 “don’t need” partitions are correct. But as long as you are willing, despite the score, there is no performance impact (otherwise the dual system will not live). external hard diskSSD OEMram ddr4
