Is SSD good? A super abnormal test will tell you!
|
After you understand computers, you will often be asked two questions by people around you. First, what if my computer is broken? Second, why is my computer so slow? If it is broken, you go and fix it! If it is stuck, what should I do? The reasons for computer lag are nothing more than these two situations: Simulation scenario 1: After seeing the computer configuration list, it would be strange if it is not stuck. The configuration was ten years ago and it should be eliminated; Simulation scenario 2: The new computer, Intel 7th generation Core i7 processor + NVIDIA GTX1080 Ti flagship graphics card, why is my computer still stuck? I am so depressed... There is no need to be depressed, because your computer "recharge" is still not enough. That cheap mechanical hard drive is so slow that it makes you doubt your life. It should have been retired long ago. No matter how strong the CPU and graphics card performance of your computer is, the system disk must be equipped with an SSD solid state drive. There are a lot of complaints about the shortcomings of mechanical hard drives: 1. Slow speed. The mechanical structure determines the upper storage mechanism, which is not just half a beat slow. Moreover, mechanical hard drives mainly improve read and write performance through rotation speed. Such a simple and crude method can easily reach a technical bottleneck, and this bottleneck cannot be broken through. The most powerful HDD hard drive has a continuous read speed of no more than 200MB/s, and the 4KB random performance is absolutely tragic. 2. Very expensive, mechanical hard drives are prone to failure, and the most feared mechanical structure is bumping, especially for hard drives that are running at high speed during operation. Any careless vibration may cause damage to the data in the disk. 3. Large size and weight, like a brick; the noise can be high or low, and some are enough to drive people crazy; the temperature is high, and the highest temperature during operation reaches about 40 to 50 degrees. On the other hand, the advantages of SSD are countless: 1. SSD integrated circuits, without any mechanical parts, can quickly and accurately access any position of the drive. If the mechanical hard drive is a diesel locomotive, then the SSD is equivalent to a high-speed train. The speed of SSD accessing data is more than 100 times faster than that of HDD. 2. Without mechanical parts, there is no mechanical failure, shockproof and drop-resistant, and it is not afraid of bumps and bumps in daily work. 3. Small size, 2.5-inch disk body, some M.2 SSDs are even smaller and thinner; when working, there is no noise, absolutely silent. The working temperature is low, and the highest temperature during operation is only about 30-40 degrees. Choose SSD and abandon HDD? If HDD still has the capital to brag, then the only thing left is capacity and price. Now a single 12TB capacity mechanical hard disk is already on sale, and the maximum capacity of SSD is still 2-4TB. The key is still the price. The price of 1TB HDD is 300 yuan, and the price of 1TB SSD is 3,000 yuan, and the price difference is 10 times. However, this advantage will not last too long. After the price of large-capacity SSD drops in the next few years, HDD will be completely eliminated. Well, believe me, your computer needs a 240G SSD now! The price of large-capacity SSD is too expensive to afford. Undoubtedly, 240G SSD is the first choice at this stage. The capacity of the system disk is sufficient and the price is moderate. The top priority for mainstream platforms is to choose a 240G SSD, which will greatly improve your computer operation experience. Here I recommend a new A400 240G SSD from Kingston, a well-established storage manufacturer. It uses Phison PS3111-S11 controller and Toshiba's original 15nm TLC flash memory. It is positioned in the entry/mainstream market and has good performance. Next, let's actually experience it and see what intuitive changes Kingston A400 240G SSD PK a 1TB Western Digital mechanical hard drive brings? I believe that netizens who are familiar with SSDs or have already used SSDs have guessed the outcome. It must be that Kingston A400 240G SSD wins, and the mechanical hard drive is almost completely defeated. You can notice the 4K random read and write performance that is closely related to daily applications. The random read speed of Kingston A400 240G is 30MB/s, and the mechanical hard drive is only 0.7MB/s, which is 42 times worse. The 4K random write performance is 96MB/s, and the mechanical hard drive is only 1.6MB/s, which is 60 times worse, which is very intuitive. The gap is not only reflected by the test software, but also by the actual experience of how the A400 240G SSD abuses the HDD? The performance gap can be clearly reflected in various daily applications, such as the speed of your power on and off, the speed of opening Photoshop software, and the speed of loading pictures. Kingston A400 240G SSD is far ahead of the mechanical hard disk. In addition, the speed of loading games, the speed of opening PPT documents, and the speed of accessing movies and music files to the hard disk... The same system, the two are different to give you a very different feeling. That kind of extreme speed will make you fall madly in love with SSD. At this time, I guess you may want to slap it over. What's the use of light speed? Is SSD durable? Is it not durable? Next, [ Editor's Suicide Series], fall from a height of 2 meters or even 10 meters, and crush it with a car... Come and abuse Kingston A400 SSD and Western Digital 1TB mechanical hard drive. High energy ahead, the old driver leads the way, quickly check in and get on the car. A little test: 20cm drop from a height of 20cm. Kingston A400 240G was completely fine, and the mechanical hard disk had no damage on the appearance. After testing, there was no damage, and it could still withstand the "torture" of 20cm height. Don't do it if you don't want to die: 1 meter drop from a height of 1 meter. Kingston A400 SSD still had no pressure at all, but the mechanical hard disk was more damaged. After the machine test, it was almost damaged. After the machine was turned on, there was obvious mechanical failure noise, beeping. Completely doing it: 2 meters drop from a height After falling from a height of 2 meters, there was a certain impact force, but Kingston A400 240G SSD still did not suffer much impact, and the machine test was completely normal. Due to the strong impact, the mechanical hard disk had a corner knocked off and was completely broken, and could not be turned on. SSD continues to be abused: dropped from a height of 10 meters The mechanical hard disk has been killed, and the SSD is still abused. From the fourth floor, nearly 10 meters high, the Kingston A400 240G SSD was dropped. Its aluminum alloy appearance is very solid. Except for some bending on the front of the shell, it is basically fine, and it can still boot normally. It is strong and needs no explanation. This is not enough: drive over it This is not enough. Drive over the Kingston A400 SSD. The solid outer shell will not be greatly deformed. After a series of violent tests, it can be seen that the impact resistance of the SSD is very strong. Experimental data shows that the vibration (20G) that the SSD can withstand is 40 times that of the HDD (0.5G), and the impact that can be withstand is up to 1500G (the impact that the traditional HDD can withstand does not exceed 350G). SSD is the wise choice, easy to use and not expensive After performance testing, application experience comparison and various self-destructive tests, it is once again proved that the excellent performance of SSD in all aspects. Installing an SSD can greatly improve the response speed of your computer. We recommend installing an SSD even for an entry-level host computer that costs 2,000 yuan. The price is not unacceptable now. For example, Kingston A400 240G sells for 589 yuan on e-commerce platforms, which is completely sufficient for a system disk. It is easy to use and inexpensive, and is a wise choice for you. If your old computer does not have an SSD, then please upgrade it to an SSD; If your computer is equipped with high-end CPUs, graphics cards and other hardware, and it is still lagging, then please be sure to...
