share with you the key points of three settings for SSD drives

The key to opening AHCI is:

AHCI, all called Serial ATA Advanced Host Controller Interface (serial ATA Advanced Master Interface)

The potential acceleration capability of SATA drives, which can increase the read/write speed of 30% hard disk. When installing a solid-state drive, turn on AHCI to give full play to hard drive performance.

The current mainstream motherboards are basically the default to open the AHCI option. However, a few motherboards, as well as older motherboards, have to manually change the default IDE option to the AHCI option via the BIOS setup.

In addition to being able to see if AHCI mode is turned on in the motherboard, you can also test the software as SSD benchmark to determine if AHCI is turned on

4K alignment to fly up:

4K alignment is a hard disk that conforms to the "4K sector" definition format and writes data according to the "4K sector" rule. With the continuous expansion of the hard disk capacity, so that 512 bytes per sector is no longer so reasonable, so that each sector 512 bytes to 4.96 bytes per sector, also said now the "4K sector."

In the age of solid-state hard drives, if 4K is not aligned, it will not only greatly reduce the data write and read speed, but also increase the number of hard disk unnecessary write times, affecting life.

So in the use of solid-state hard drives, you must first 4K alignment, in order to let the solid-state drive really fly up.

In daily life, we can directly use a number of professional hard disk partitioning software to achieve 4K alignment, such as Diskgenius (hard disk partition), Division assistant.

Use as SSD benchmark software to see if the SSD is 4K aligned, as shown in the red box below, if the word "OK" is followed by a number such as 1024,2048, the SSD is 4K aligned. If the word "OK" is not there, the 4K is not aligned.

(note): If the number in front of "OK" is very large and is not a number such as 1024,2048, the hard drive divides the hidden partition when the operating system is installed.

A 100M hidden partition is automatically generated when the Win7 system is installed

A 350M hidden partition is automatically generated when the WIN8 system is installed

As long as you do not keep the hard disk hidden partition before the C disk, the "OK" front will show numbers like 1024,2048. If you keep it, the number in front of "OK" will become very large.

Keep Drivers & firmware updates

In addition to the above settings, we also need to frequently obtain the latest solid-state hard disk and firmware from the hard disk manufacturer, so that we can combine the hard and hard solid state drive to achieve the best working condition.

Well, I don't know if you're using a solid-state drive. Did you learn to do it? No, just look at it from the beginning again, the above points are done, your solid state hard drive can not be counted as white buy.

Solid State Hard Drive Academy:

1, read and write speed, the use of flash memory as a storage medium, reading speed relative to the mechanical hard disk faster. Solid state drives do not use heads, seek time is almost 0, solid-state hard drives continue to read and write faster than the 500mb/s!

2, physical characteristics, low power consumption, no noise, vibration, low heat, small size, operating temperature range. Solid state drives do not have mechanical motors and fans, with a noise value of 0 decibels at work.

The solid-state hard disk based on flash memory has lower energy consumption and calorific value under working state. There is no mechanical moving parts, no mechanical failure, no fear of collision, shock, vibration. Most solid-state drives can work in-10~70摄氏度.

M.2 formerly known as the NGFF interface, it is for the ultra-polar (ultrabook)-Tailored new generation of interface standards, mainly used to replace the mSATA interface, with small size, performance mainstream characteristics.

Today's m.2 interface to the PCI-E 3.0 x4 channel, the theoretical bandwidth reached 32Gbps, compared to the previous level of a lot of improvement, which also allows the SSD performance potential increased significantly. In addition, the interface SSD also supports the NVME standard, compared with the current AHCI, through the new NVMe standard access to the SSD, in the performance improvement is very obvious.

The mSATA interface is a mini version of the standard SATA, which transmits signals via the mini PCI-E interface, which supports 1.5Gbps, 3Gbps two modes.

mSATA will provide the same speed and reliability as the current SATA interface standards due to the small size of the mSATA MINI pci-e SSD, more and more notebook products begin to use the laptop hard disk of this interface. Computer knowledge
