How to see whether the SSD is 4k or not? Check whether the SSD is 4K or not.

Friends who know SSD know that 4K alignment is a very important operation when partitioning the SSD. If the SSD does not have 4K alignment, it will cause a span. Reading and writing not only affects the speed of the solid state drive, but also affects the life of the SSD. So, how does the SSD look 4k aligned? After a lot of friends bought a new computer built-in SSD or upgraded SSD installed system, how to check whether SSD is 4K aligned? Today, the computer Pepsi network has brought two simple viewing methods, let's take a look.

Method 1: View the method without any tools

1, first use the "Win + R" combination shortcut to open the run command box, then type after opening "msinfo32" and click “OK”Open as shown.

2. After opening the system information window interface, click on "Components" - "Storage" - "Disk" on the left, and then on the right side, "Partition start bias" Move the value & rdquo; as shown.

Check if the SSD is 4K alignment method

3, and finally divide the 2 "partition start offset values" on the right side by 4096 (the following is an example of a small SSD notebook value) The calculation results are as follows.

1048576 ÷ 4096 = 256

64426606592 ÷ 4096 = 15729152

As shown above, the size of the 2 partition start offset of the small SSD notebook is divided by 4096. All are integers, which means that the SSD is already aligned in 4K. If the result is a non-integer followed by a decimal point, the SSD is not aligned.

This method of viewing SSD alignment is very useful, especially for some friends who do not have the relevant SSD detection tool installed on the computer and have no network download. Thanks to the calculator or mobile phone calculator in the computer. It is also very simple to calculate.

Method 2: View with tools

Using some hard disk detection tools, such as DiskGenius, AS SSD benchmark, etc. to view disk 4K alignment information is also very simple, first download one in the computer with SSD The hard disk detection tool can then be viewed by opening it and running it as shown.

Use tools to check whether SSD is 4K alignment method

What if I see that the SSD is not aligned? This is also a good solution, no re-partitioning hard drive and loading system, you can also easily 4K alignment. See the tutorial for details: "How to 4K Align the Solid State Drives? 3K Alignment Methods for Solid State Drives."

The next page is for extended reading: SSD 4k alignment is 2048 or 4096.

4k alignment What does solid state hard disk 4k alignment choose 2048 or 4096

Article last simple science What is the meaning of SSD 4K alignment? When performing SSD 4K alignment, choose 2048 or 4096 alignment.

What does 4K alignment mean?

4k alignment is a term used in hard disk partitioning. 4K alignment is a hard disk formatted according to the 4K sector definition, and data is written according to the rules of 4K sectors. In general, when partitioning a solid state drive, be sure to check the 4K alignment, otherwise it will affect the performance and life of the SSD.

Popularly, if the SSD does not perform 4K alignment, the write point of the write data will be between two 4K sectors, that is, even if the minimum amount of data is written. Two 4K sectors will be used, which will cause cross-region read and write, and the number of reads and writes will be enlarged, thus affecting disk performance. In addition, the lifespan of SSD is also of great concern to everyone. It is also conceivable how long SSDs can be read and written over time.

Solid hard drive 4k alignment is 2048 or 4096?

4K aligned 4K in SSD refers to 4096 bytes, of which 1 sector is 512 bytes.

Some people mentioned that the solid state hard disk 4K alignment 2048 refers to 2048 sectors, that is, 512B * 2048 = 1048576B = 1024KB, that is, 1M alignment, and meet 4K alignment, the value as long as 4096B The multiple is 4K alignment. In theory, 4K alignment can be as long as 4096 integer multiples, but the standard is generally 4069.
