SSD is really good, although the capacity and price are still a lot of people spit, but the current price is already relatively cheap. Buy a small-capacity SSD to install the operating system and commonly used software, can greatly improve the performance of the entire machine. This improvement is obvious. There are a lot of people who have used SSDs and they never want to switch back to HDD. The author is one of them. As the current installed hardware, do you use SSD? Did you use SSDs like the HDD era? Why do you buy SSDs that are the same as everyone else, but people's SSDs are fast and yours is slow? To make SSD really play its performance, it must go through a series of settings. For example, using a native SATA 3.0 interface, turning on AHCI, 4K alignment, installing a dedicated driver, etc., SSDs are actually more complicated than traditional HDDs, but they are not complicated. It is not difficult to see from the large amount of evaluation data that improper use of the SSD will greatly affect the performance and lifespan of the SSD. Therefore, properly understanding some common knowledge of the SSD can better achieve the performance of the SSD. Let new SSDs not be slow.
The SSD hard disk requires the interface type of the mainboard, and it must use the SATA3 (6Gbps) interface to display its performance. Although the previous SATA2 (3Gbps) interface can be used, it cannot really play the role of SSD hard disk. The SATA3 (6Gbps) interface is divided into two types: native and third-party chips. The performance of third-party chips is not as good as that of the native ones, which affects the speed of SSDs. So it's best to use native ones. In addition, the data line must also use SATA3 (6Gbps). (Intel Southbridge's support for SSD is better than that of AMD, so if you want to experience the high performance of SSD, it is still the first choice for intel motherboards. In addition, SSD hard disks have interfaces such as mSATA, M.2, PCI-E, which are not described here. Only talk about the most popular SATA3 interface.)
Now basically all new motherboards support SATA3 (6Gbps) interfaces. Many motherboards also support M.2, SATA Express and other interfaces.
For users of old motherboards and old laptops, how do you check if your motherboard is a SATA3 (6Gbps) interface? The most convenient way is to look at the product manuals or to check the official website for related information. If none of these can be found, you can use the CrystalDiskInfo software to view the SSD information. When SATA/600 is displayed in the transmission mode, the SSD is on the SATA3.0 interface. If SATA/300 is displayed, it is not an SATA3.0 interface. It is recommended to replace the motherboard. In addition, we can also use this software to check whether the SSD is new, and it can be seen from the number of power-on and power-on time.
The current mainstream motherboards basically have the ACHI option enabled by default. However, a few motherboards, as well as previous old motherboards, have to manually change the default IDE option to the ACHI option through BIOS settings.
The current mainstream motherboards basically have the ACHI option enabled by default.
How to check if SSD has ACHI option enabled? Can generally be viewed in the BIOS. Of course you can also use the AS SSD Benchmark software to view. As shown in the red box above, if the word "OK" appears, the ACHI option is enabled.
You can directly use the win7, 8 or win10 system built-in disk management tools to perform the formatting operation. After using the win7, 8 or win10 system's built-in disk management tools for formatting, 4K alignment is automatically implemented. You can also use some professional hard disk partitioning software to achieve 4K alignment. For example, DiskGenius (hard disk partition), partition assistant and other software can perform 4K-aligned operations.
When the new SSD is used for the first time, you can use the partition assistant to perform 4K-aligned operations on the SSD.
You can also use DiskGenius to perform 4K alignment operations.
How to check if your SSD is 4K aligned? Generally can use AS SSD Benchmark this software to check, as shown in the red box above, if there are words like 1024, 2048 followed by the word "OK", the SSD is already 4K aligned. If there is no "OK", 4K is not aligned. If the number in front of "OK" is very large, not a number such as 1024, 2048, then the hard disk partitions the hidden partition when installing the operating system. When installing win7 system, it will automatically generate 100M hidden partition. Win8 system automatically generates 350M hidden partitions during installation. As long as the hard disk hidden partition before the C drive is not retained, numbers such as 1024, 2048 are displayed in front of “OKâ€. If you leave it, the number before "OK" will become very large.
(Supplementary Note: The new SSD hard disk will automatically be 4K aligned when installing the win7, 8 operating system. However, hidden partitions will also appear. For win7, 8 hidden partitions, Microsoft's official explanation is: 1, BitLocker's regulations, boot files Separated from Windows files, this system partition can use utility software, such as backup, dual boot support.2, to prevent accidental deletion, if the startup file is saved in the system partition, it is easy to reload the system partition, and the format Loss of these startup files.The drive does not have a drive letter can be very good to prevent accidental deletion of the boot file.Win7,8 hidden partition brings the disadvantages: 1, can not use the GHOST version of the system CD to install win7, win8, can only use the installation The installation of the version is performed step by step 2. After the system is installed, you cannot use Wingho, OneKey Ghost, etc. to perform system backup 3. The Norton Partition Magic cannot be used normally if you try to repair the 100M, 350M partition , Will cause the installed win7, win8 can not boot.4, with 100MB, 350M partition win7, win8 activation will be large A large decrease will affect the activation probability of the system.)
How can the hidden partition not appear when installing the SSD? The easiest way is to partition the new SSD ahead of time. Instead of partitioning when installing the operating system.
For most SSD products, the drivers that come with operating systems such as win7, 8, and 10 are relatively stable. The driver does not need to be installed by the user because the installation of the driver is automatically completed when the operating system is installed. The Intel RST driver can improve the performance of some SSDs. At this time, users need to download and install them.
The Intel RST driver can be easily downloaded from Intel's official website.
Intel RST driver is recommended to download the latest version, there is a bug in the old version.
After installing the Intel RST driver, a reboot dialog box appears. Intel RST driver installation is complete after restarting the computer.
The word "msahci" in the red box of the AS SSD Benchmark software represents the driver for the win7 operating system. The word "iaStorA" in the red box indicates that the driver is an Intel RST driver. After using the Intel RST driver, it can be seen that the performance of the Toshiba DTS312 128G SSD is significantly improved, and the overall performance is much better than using the win7 system's own driver. This shows that Toshiba DTS312 128G SSD is more suitable for Intel RST driver. (In general, most SSDs can improve performance after replacing the Intel RST driver. However, with a small number of SSDs, the performance of the Intel RST driver will be reduced. Therefore, you must select the driver that your SSD is suitable for.)
5: Do not fully fill the SSD capacityTo retain a certain amount of space (reserve 10% of the capacity in the SSD), it is more conducive to its performance. And full-loaded SSDs are more likely to crash. (Because of the main control, some SSDs will not lose speed when they are fully loaded, and some SSDs will lose speed if they are fully loaded.)
The Trim command, also called disable delete notify, is a technical instruction of the ata8-acs2 specification. When using SSDs, be sure to turn on the Trim command in the system. The Trim command is a technology that comes with the Win7 and Win8 systems. The system is enabled by default. XP or lower versions of the system do not have Trim technology. XP systems are not recommended to use SSDs. (Generally the default is open.)
How do you know if Trim is turned on in your computer?
Click on the Start menu and enter CMD in the search bar
Right-click on the search result icon and choose to run with administrator privileges
Enter "fsutil behavior query DisableDeleteNotify"
If the return value is 0, your TRIM is on
If the return value is 1, it means that your TRIM is closed
(Note that some SSDs do not support Trim.)
In general, it is most convenient to delete the hard disk and then repartition the partition to make 4K alignment. However, if you do not want to reinstall your operating system, you can use Paragon AlignmentTool software for lossless alignment. (Note that important data is not necessarily 100% successful.)
The left side is your hard disk, while the right side is a description. If it is green, it is already aligned 4K, while the yellow is displayed, it can be aligned 4K, but not aligned, and pink, it does not support advanced format It is useless to align 4K. Select the yellow misaligned hard drive, check it, then click Align Partitons below.
When you align the system disk, it will reboot and jump to DOS for alignment. This process depends on the size of your hard disk and the amount of use. The fewer files in the hard disk, the faster the alignment, and the Aligned but do not want to reinstall the system friends. During this process, the computer should not be powered off. Do not force the alignment process to stop. Otherwise, the hard disk may be damaged! Also to remind, pay attention to backup. (Because my hard drive is all 4K-aligned, there is no way to do a detailed demonstration. You can find relevant instructions on the Internet.)
In addition, the software such as the partition assistant can also be used for 4K alignment.
SSD hard disk write life is limited, such as mechanical hard disk settings, open system restore, using defragmentation and the like, it will hurt SSD hard drive. So disable unnecessary operating system features. However, manually disabling them one by one can be troublesome, so using some optimization software will save you a lot of work. For example, 360, QQ butlers, and some of the big brands SSD optimization software comes with these features. Here I present the SSD Fresh ssd hard drive optimization software.
SSD Fresh 2015 is a professional SSD solid-state disk optimization tool that can reduce the number of SSD disk read and write, greatly extending the service life! SSD Fresh works by turning on or turning off some of the system's features related to SSD performance and longevity, such as turning off disk indexing, shutting down sleep, and turning off virtual memory.
