It's widely acknowledged that mechanical hard drives are slower compared to solid-state drives, especially when considering the difference in performance between traditional and modern storage technologies. However, many users still want to squeeze out more speed from their mechanical drives. Today, we’re sharing some effective optimization techniques. Keep in mind that while these methods can improve performance, they won’t turn a mechanical drive into an SSD. They’re more about maximizing what you already have. While features like TRIM and 4K alignment are important, they aren't covered here. If you're interested, check out our previous articles for more details. The focus today is on further optimizing your mechanical drive under Windows. One of the first steps is to disable the Indexing service. For each drive (C, D, etc.), right-click on the drive letter, go to Properties, and uncheck "Allow files on this drive to be indexed." This reduces system lag and makes folder navigation faster, even if the improvement isn’t dramatic, the user experience is noticeably smoother. Next, go to the Tools tab in the drive properties and click on "Optimize." In the window that appears, select "Change Settings" and uncheck "Run by Schedule." This feature is not very useful for NTFS drives and runs in the background, which can slow down your disk. Disabling it is a simple way to free up some resources. Another technique involves reducing the frequency of read/write operations on the hard drive. This can be done by modifying the system.ini file and adjusting how virtual memory is used. On Windows 8 and above, you can access system.ini through the Start menu. Add the line "ConservativeSwapfileUsage = 1" under the [386Enh] section. This tells the system to use virtual memory only after all physical memory is exhausted. Then, add a "[vcache]" section at the bottom with two lines: MinFileCache=4096 and MaxFileCache=8096. This sets a buffer of 4MB to 8MB for small file operations, improving performance on mechanical drives. Keep in mind that these optimizations help improve the efficiency of your mechanical drive but cannot make it as fast as an SSD. They reduce system overhead and allow the drive to perform better within its limitations. If you're looking for a significant speed boost, upgrading to an SSD is still the best option.
ELCB is an acronym for Earth leakage circuit breaker, which is a device placed inside a water heater, commonly referred to as ELCB electric leakage breaker. This circuit breaker has the function of disconnecting the device from the circuit whenever an electrical leak occurs through the human body when touching the electrical parts of the device.
ELCB is to limit the incident of electric shock inside the machine, disconnecting the power when there is a problem, ensuring safety for human life as well as fire and explosion prevention.
ELCB is often used in both civil and industrial applications.
For the domestic electricity system, the installation problem is not difficult, but in industry, the anti-shock for workers and the prevention of electrical leakage for electrical equipment with large capacity requires a bridge. Automatic anti-shock, high-power leakage protection, and often has a much higher price.
