First of all, we have to understand how to call "love the hard disk", because in the current Windows system environment, not only the user will use the application software to send and write instructions to send the hard disk Load, but in any case of idle, 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 flashing. In fact, this is normal. of.
Every 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's Windows 8 Release Preview version, users responded to the problem caused by high hard disk load. This is because in the RP version, the system performs a scan every time the user operates Defender, including scanning a folder, so it is caused by the card, 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.
Superfetch and mixed startup troubles
Superfetch (super pre-read) problem
The other is Superfetch (super pre-read) 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.
It is said that 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).
You can disable Superfetch
here. So if the average user feels that the hard disk utilization is too high, the usage experience will drop, and 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 (hybrid boot) service problem
In fact, the most discussed now is the new Hybrid Boot hybrid start service brought by Windows 8, this service refers to the majority of the system when Windows 8 is shut down. Core systems such as drivers, system services, etc. 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 in 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 optimization and upgrading from HDD to SSD
Disk defragmentation and optimization
Finally, let's talk about "defragmentation function", if you use HDD mechanical hard disk, Windows 8 will open "Automatic Fragmentation" Finishing function & rdquo;, defragmentation when the system 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 mark after SSD is idle to improve garbage collection efficiency. Of course, you can also use the SSD vendor-specific tools for manual optimization, 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.
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.
Many 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 appeared in Windows XP, Vista, Windows 7 just released. However, there has not been a problem that the new system causes the hard disk to be scrapped in a large area. 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.
