Editor to share with you what the new win7 solid state disk points for attention, I hope you will learn something after reading this article, let's discuss it together!

1. Check whether the solid state drive is brand new.

The first choice is to choose solid-state drives to avoid the old models that have been discontinued. After the new disk is available, first check the power-on times and time with CrystalDiskInfo software, which can prevent most profiteers from using the old as the new. The normal power-on times should be 1 or 2, and the power-on time should be 0, otherwise it will have been used by people.

Generally speaking, the newly manufactured SSDs do not have partitions and are shown as Disk X in CrystalDiskInfo. If you buy a new disk with a partition letter or even documents inside, it is time to talk with the seller about the return compensation.

two。 Confirm that AHCI mode is turned on on the motherboard

This step is necessary for computers purchased three or five years ago, while newly installed computers have AHCI turned on by default. Press the Del key to enter the BIOS setting, find SATA Mode Selection in the Advanced menu, and make sure it is set to "AHCI", so as to ensure the full performance of the SSD.

This step must be done before installing the system, otherwise you will have to go back and install it again, which is a heartbreaking experience for many players.

3.4k alignment to fly

4K alignment refers to the hard disk formatted in accordance with the definition of "4K sector" and writes data according to the rule of "4K sector".

With the development of the times, the capacity of the hard disk continues to expand, so that the previously defined 512 bytes per sector is no longer so reasonable, so the 512 bytes per sector is changed to 4096 bytes per sector, which is now commonly known as "4K sector". As NTFS has become a standard hard disk file system, the default allocation unit size (cluster) of its file system is also 4096 bytes. In order to make the cluster correspond to the sector, even if the physical hard disk partition is aligned with the logical partition used by the computer, to ensure the efficiency of hard disk reading and writing, so there is the concept of "4K alignment".

In the solid-state disk era, if 4K is not aligned, it will not only greatly reduce the data writing and reading speed, but also increase the unnecessary write times of the solid-state disk and affect the life.

So when using a solid-state drive, you must first do 4K alignment before the solid-state drive can really fly.

In daily life, we can directly use the win7,8 or win10 system built-in disk management tools for formatting operations to achieve 4K alignment. You can also use some professional hard disk partition software to achieve 4K alignment.
