First note: Let’s look at the capacity. Some SSDs are 250g, some are 500g, and some are 1TB. The larger the capacity is, the more expensive it must be, because it can store more information.

Second note: Pay attention to the interface types of SSDs. Although they are all SSDs, some are M.2 interfaces and some are SATA interfaces. They represent two different interface types.

Third note: If all SSDs have M.2 interfaces, but they also have different protocol types, some SSDs do not have the NVME protocol, and some SSDs support the NVME protocol. Their read and write speeds will be faster, so their prices will be more expensive.

Fourth note: Pay attention to the read/write speed of the SSD. Different speeds and prices are different. The relationship between the read/write speed and the support of the SSD is that some support pcie4.0 and some support pcie3.0. If the motherboard supports it, the speed of the solid-state drive on pcie4.0 will be faster.

Fifth note: Different brands may use different particles, which also determines the service life and quality of SSDs. Of course, the quality is good and the price is expensive. Now you know why.

We should first analyze the cause of computer jams. Generally, a computer jam is nothing more than two cases. The first is software problems. This is a system problem. We can solve it by reinstalling the system. The second case is the hardware problem. This installation system cannot solve it. You can only upgrade the hardware and improve its skills.

For upgrading hardware, we will summarize some methods for upgrading.

In the first case, when you open more programs, the computer gets stuck. Generally, the CPU or memory usage is too high. The task manager looks at the CPU utilization rate and the memory utilization rate. It is recommended to upgrade the memory of the same brand and model. In this way, the compatibility will be better. When upgrading the CPU, look at the CPU ladder diagram. According to the market situation and your own capital budget, you can choose the right CPU.

The second case is that your computer plays games. The frame rate is low and the picture is stuck, which is the problem with the video card. It is worth noting that the power consumption of a better video card may be higher and the requirements for power supply will be higher. Therefore, you should pay attention to the insufficient power rating of your own power supply. It is recommended to upgrade to a higher power supply at the same time.

Third, the computer is an old computer. The mechanical hard disk has been used for more than 3 to 5 years. In this case, the basic mechanical hard disk will cause bad tracks. At this time, we should consider upgrading to a solid-state hard disk. The price of SSD is not very expensive, and the speed of improvement is great. It is more than five times that of the mechanical hard disk. Pay less and increase speed. Generally, the biggest bottleneck of an old computer is the mechanical hard disk, so upgrading to a solid state is one of the best solutions.

As a world-famous PC brand, HP notebook computers are mainly oriented to business, so the overall operation speed of HP notebook computers is fast, and the appearance is thin and light. The disadvantage is that the battery life is short and not suitable for playing games.

Dell laptop, like HP laptop, is a world-famous PC brand, and Dell laptop is also a positioning office field. The advantage of a Dell laptop is its durability. A Dell laptop can be used for many years without being stuck or dead. In addition, Dell computers have a good dust-proof effect. Even if they have been used for many years, the fans of Dell laptops have little dust. Although Dell laptops are very durable, the appearance design of Dell laptops is uglier than that of other notebook brands, and Dell laptops are expensive. Compared with other laptops with the same configuration, Dell laptops may be more expensive.

The advantage of the Lenovo laptops is that the after-sales service is very good, and the after-sales service of the Lenovo laptop is also very good, and the after-sales service attitude of Lenovo laptop is very good. As long as the Lenovo laptop fails, you can give priority to Lenovo after-sales service for maintenance. In addition to the above advantages, Lenovo has a relatively large number of laptop models, including game books, office books, teaching books, and other types of Lenovo laptops. Consumers can choose a laptop that suits them according to their own needs. In terms of defects, Lenovo laptops are prone to be stuck and crashed after a long time of use. Occasionally, the body gets hot. One-click restore system or reinstall system can be considered as a solution.

Asus laptop, a computer brand from Taiwan Province of China, has the advantages of smooth operation, relatively good heat dissipation, and relatively high-cost performance. In terms of defects, there are relatively few after-sales service sites for ASUS laptops. Once there is a fault, it is possible to go to a third-party maintenance site to repair it to a certain extent. In addition, although ASUS laptop has a high cost-performance ratio, their quality is relatively poor compared with other mainstream laptop brands in the supply chain, so the ASUS laptop is prone to failure relatively frequently.

On the whole, HP, Dell, Lenovo, and ASUS all have their own advantages and disadvantages. If it is a daily office, I think Dell laptops are recommended; If you want to buy a laptop with a high cost-performance ratio, it is recommended to use an ASUS laptop; However, on the whole, Lenovo’s laptop is better, because it can give consumers more choices.
