"Win8 system hurts the hard drive" big break

First of all, we have to understand how it is called "injury hard disk", because in the current Windows system environment, not only when the user uses the application software to send and receive instructions to send The load on the hard disk, but in any idle situation, Defender, Superfetch, etc. will work in the background and cause load, so when the user does not use the computer, it will be uncomfortable to see the hard disk indicator light flashing, actually this is normal.

Each generation of operating systems will optimize the data structure, in order to have better performance in future applications, so the increase in the load on the hard disk is inevitable. Is it true that the system with a slightly higher load on the hard disk is a system that "insured the hard disk"? This statement is obviously a bit exaggerated.

Windows 8 RP Defender Service Issues
Windows Defender

First, let's take a look at Defender. In the last year Windows 8 Release Preview version, there was a user reaction in use due to high hard disk load. And caused by the card, this is because in the RP version, the system will perform a scan every time the user operates the Defender, including opening a folder and scanning it once, so the card is caused, especially the user of the mechanical hard disk. Fortunately, Windows 8 RTM has fixed this problem, so users who are still using the RP version will upgrade to RTM as soon as possible.

Trouble with Superfetch and Hybrid Startup

Superfetch (Super Pre-Read) Problem

Another is the Superfetch service. This technology Microsoft has been used since Windows Vista, its predecessor is Windows XP "Prefetch". This technology is designed to record the usage status of the app on the hard disk after the user starts an app. When the app is started again, it will directly read the last saved state, thus improving the running speed.

To put it bluntly, Superfetch can automatically convert the swap file stored on the hard disk into the memory page according to the user's usage habits, so that the speed of the program that the user frequently runs is further accelerated. As a result, the hard disk naturally has a certain occupancy rate. From Vista to Windows 7 to Windows 8, this technology has been used, which is why many users originally upgraded from XP to the new system obviously feels that the hard disk load is high.
Superfetch Service in System Services

So Superfetch is very important to all users? Earlier, Kai-Fu Lee said: SuperFetch service is designed for enterprise applications and large-scale collaboration software, used in large enterprises. Professional software and enterprise policy management, the database startup process will be up to 10 minutes. And with SuperFetch, the startup time can be reduced to less than 6 minutes, and for individual users, the daily software itself is usually used for startup time. Short, usually within 1~2 seconds, SuperFetch speed is only 0.2~0.5 seconds at this time, which can be considered as no effect, and will increase the monitoring of the hard disk (loss of CPU performance time) and reading time. (Increase hard disk IO addressing thread allocation).
Superfetch

can be disabled here. So if the average user feels that the hard disk utilization is too high and the experience is reduced, it can be turned off without affecting the performance. In fact, the daily use of individual users is often in a multi-tasking environment where multiple applications are frequently switched. The random operation performance of mechanical hard disks is a great bottleneck. In this case, the use of SSDs will be much faster. Moreover, when the system detects only SSD, it will automatically close SuperFetch. Now SuperFetch has been accepted by the majority of users, it will only slightly increase the load of the hard disk, and "wound hard drive" is not the same thing.

Hybrid Boot Service Issues

Actually, the most talked about is the new Hybrid Boot hybrid startup service brought by Windows 8. This service refers to the shutdown of Windows 8. Most of the system's core systems, such as drivers and system services, are compressed into memory, and then the data is written to the hard disk through the processor. When the data is all written to the hard disk, Windows notifies it to shut down. This way, at the next boot, Windows can directly call these files without having to perform a complicated initialization process, which greatly speeds up the boot time.
The system settings for power management have a quick start option

This is actually an advanced sleep feature. In fact, all PCs will write hibernation files to the hard disk when they enter hibernation. The default size of this file is 75% of physical memory. In this case, the hard disk load will inevitably increase. This is to get a better experience at the next boot, which is not to damage the hard disk.

Disk Optimizing and Upgrading from HDD to SSD

Disk Defragmentation and Optimization

Finally, let's talk about "defragmentation" if you use HDD mechanical hard disk Windows 8 will turn on "Automatic defragmentation" to defragment the system when it is idle. Of course, you can also choose to turn off manual cleanup.

It is worth mentioning that Windows 8 has better support for SSD. We know that TRIM is a crucial instruction for SSD. Generally, it will be marked after SSD is idle. Garbage collection efficiency, of course, can also be manually optimized using SSD vendor-specific tools, the effect is better. However, not all SSD vendors have supporting management tools. Windows 8 has prepared this for us. In the disk management tool, if it is an SSD, click “Optimize” to implement TRIM.
Windows8 can be said to bring its own SSD optimization tool

However, some statements about switching from HDD mechanical hard disk to SSD will not hurt the hard disk. It is obviously unreasonable. The reason for this is nothing but because Users almost never experience delays when using SSDs, unlike HDDs, which flash for a long time. This is actually because the response time of the SSD is much faster than the HDD, but in fact the load of both is the same.

A lot of users are misled by some rumors on the Internet, and mistakenly understand that the hard disk load is slightly higher than before. It is "injury hard disk", which was just released when Windows XP, Vista, and Windows 7 were released. It has appeared, but there has not been a problem that the new system has caused a large area of ​​the hard disk to be scrapped. We recommend that the majority of users still have a correct attitude, the hard disk itself is a consumable item, and normal use does not have to be worrying.
