How to see if SSD drives are 4k aligned to see if SSD is 4K aligned

4K Alignment is a very important operation when the SSD is partitioned, if there is no 4K alignment, it will result in the cross region reading and writing, not only affect the speed of solid-state drive, but also affect the SSD life. So, how do solid-state drives look like 4k aligned?

Method One: Do not use any tool to view the method

1, first use "win + r" combination shortcut key to open the Run Command box, and then open the following type "msinfo32", and click OK to open, as shown in the picture.

2, open the System Information window interface, click on the left side of the "Component"-"storage"-"Disk", and then on the right to see "Partition Start Offset value", as shown in the figure.

To see if SSD 4K alignment method

3, finally the right 2 "Partition start offset value" divided by 4096 (below the small number of SSD notebook values as an example), the results are as follows.

1048576÷4096 = 256

64426606592÷4096 = 15729152

As pictured above, the 2-item partition starting offset value of the small-weave SSD notebook is all integers divided by 4096, indicating that SSD is 4K aligned and if the result is a non integer, followed by a decimal point, the SSD is not aligned.

This way to see if SSD alignment is very practical, especially for some computers do not have the relevant SSD detection tools, and no network download the friend is very practical, with the help of computer calculator or mobile phone calculator, to calculate also very simple.

Method Two: View with tools

With some hard disk detection tools, such as Diskgenius, as SSD benchmark, and so on to see the disk 4K alignment information is also very simple, first in the SSD equipped with the computer to download a hard disk detection tool, and then open the run can be viewed, as shown in the figure.

Use tools to see if SSD 4K alignment method

What if you see the solid State drive is not aligned? This is also a good solution, no repartition hard disk and loading system, can also easily 4K alignment. See tutorial: "SSD 4K alignment 3 Solid state hard Disk 4K alignment method".

4k alignment what meaning solid state hard disk 4k to alignment 2048 or 4096

The article finally simple popular science What do you mean by SSD 4K alignment, when you are working on a solid-state hard disk 4K alignment, choose 2048 or 4096 alignment.

What does 4K alignment mean?

4k alignment is a professional term in a hard disk partition, and 4K alignment is the hard disk that is formatted with the 4K sector definition and writes data according to the rules of the 4K sector. In general, in the SSD to partition the time, must be checked on the 4K alignment, otherwise it will affect the SSD solid-state hard drive performance and life.

In a popular sense, if the SSD is not 4K aligned, the write point that writes the data is exactly between two 4K sectors, that is, even if the minimum amount of data is written, the two 4K sectors are used, which can result in a Cross-domain read-write, read-write magnification, and thus affect disk performance. In addition, the life of SSDs is also a matter of concern, often across the region to read and write SSD how long it can be imagined.

Solid State hard drive 4k to alignment 2048 or 4096?

4K-aligned 4K in SSD refers to 4096 bytes, of which 1 sectors are 512 bytes.

Some people refer to the solid state hard drive 4K alignment 2048 refers to 2048 sectors, that is, 512B*2048=1048576B=1024KB, which is 1M aligned, and satisfies the 4K alignment, which is only a multiple of 4096B is 4K aligned, In theory, 4K alignment can be as long as 4096 integers, but the standard is generally the choice of 4069.
