4K alignment is outdated? What is 1024K and 2048K alignment?

My friends should all know that the 4K of the SSD is aligned, right? You still don’t understand, "This is really not a metaphysics SSD 4K alignment. The correct way is this! "Refer to it. But after finishing the 4K alignment partition, looking back, you may find that your partner's SSD uses 1024K alignment, 2048K alignment... What the hell is this? ! Don't get excited, I will talk about this today.

What is 1024K, 2048K alignment?

In fact, when setting the partition 4K alignment, as long as you use a multiple of 8 to set it, 4K alignment can be achieved. The so-called 1024K or 2048K, that is, the 2048 sector and the 4096 sector are aligned. Pay attention to the alignment and the starting fan when setting. The number of the zone should be expanded proportionally, and the head and sector should be directly used by the system default.

Compared with 4K alignment, the starting sectors of these two alignment methods are relatively large, so more space is left at the front end of the hard disk, which is said to provide better storage conditions for basic hard disk data such as partition tables. But these have nothing to do with our daily use, let's take a look at the performance of these two alignment methods.

Performance measurement, it is so!

So, what are the benefits of choosing such an alignment? Let's test it.

4K alignment

1024K alignment

2048K alignment

On the Win10 64-bit system of the editor, the performance of 1024K alignment and 4K alignment are very similar. The continuous read and write speed of 2048K alignment is the highest, but the read and write performance of small data drops, so the total score drops instead. In this way, 4K or 1024K alignment is a good choice, but higher alignment is unnecessary.

The multiple gap of 4K alignment is not as big as imagined, so entangled friends can rest assured that the solid state drive only needs to be aligned to 4K. For example, partitioning and formatting with Win10 is also a good choice, it will automatically optimize the SSD better, and there is no need to manually adjust it.
