As a portable data storage tool, U disk has become an indispensable assistant in our daily life and work. Whether you are a student, an office worker or a freelancer, an efficient and reliable USB flash drive can bring many conveniences. So how should we choose a USB flash drive that suits us, as far as I am concerned, I have used not a thousand but also eight hundred, I have summarized a few points, which will definitely help you.
1. What capacity USB flash drive should you choose?
For beginner users of USB flash drives, you can pay attention to the capacity first. Generally speaking, the capacity of U disk ranges from several GB, hundreds of GB or even 1TB, and we can not simply pursue large capacity when choosing, but should choose reasonably according to our own needs. For example, if you are only used to store and transfer small office or study documents, such as word, pictures, etc., then a 32GB/64GB USB flash drive can be satisfied, and if you need to copy and store some large files, such as business proposal PPT, report documents, learning materials and videos, etc., then you need a 128GB/256GBU disk to start.
Second, what does the speed of the USB flash drive mean and what is the impact?
In addition, the transfer speed of the USB flash drive is directly related to the work efficiency, so let's first learn about the knowledge of the USB interface.
Common USB interfaces include USB 2.0, USB 3.0 and even USB 3.1. Among them, the theoretical maximum transmission speed of the USB2.0 interface is 480Mbps. For the USB 3.0 interface, the maximum transfer speed is about 550MB/s. Therefore, the newer the interface model, the faster the speed of the USB flash drive. By the way, the transfer speed advertised by the USB flash drive usually refers to the reading speed, and the write speed is generally a little lower than the reading speed.
So what directly affects the reading speed of the USB flash drive? It is one of the most important components of the USB flash drive: the main control chip!
Take the U357 high-speed USB flash drive just released by aigo Patriot as an example, it is equipped with the latest main control chip YS5085 launched by Deyi Microelectronics, and the reading speed of its USB3.2 Gen1 interface is very powerful. After professional testing, the measured read and write speeds reached 453MB/s and 414MB/s, basically reaching the ceiling of USB3.2 Gen1 interface bandwidth, greatly compressing the time for copying a large number of files, and greatly improving the office efficiency of modern professionals. The aigo Patriot U357 has a nominal read speed of 440MB/s and a write speed of 400MB/s, which is almost the same as the maximum speed of the interface.
3. Why is the USB flash drive you bought so easy to break?
In addition to capacity and speed, we should pay more attention to the memory chip used in the USB flash drive, which is the decisive factor in determining the durability and quality of the USB flash drive.
The USB flash drives we see today generally use TLC flash memory particles, which are more cost-effective. Although they are both TLC, they are also different, and there are two concepts here, Good Die and Ink Die. The following content is a bit professional, so let's take a closer look.
Good Die and Ink Die are terms used in semiconductor manufacturing to describe the quality state of a single chip (die) on a wafer, and the following is a specific analysis of both:
Good Die: During the wafer production process, each chip needs to go through rigorous testing. The chips that pass these tests are called Good Die, or good particles. These good particles meet high quality standards and can be used in the manufacture of final products, and are usually only used in the manufacture of high-end products such as SSDs, solid-state USB flash drives, etc. Products made with Good Die granules are durable, fast, non-heat-free, and can be used for a long time, and of course, the price will be higher than ordinary products.
Ink Die: The opposite of Good Die is Ink Die, i.e. secondary particles or defective products. These particles fail to meet the quality requirements during wafer inspection and are therefore marked with ink on the mapping map. Bad blocks in InkDie mean that these chips don't work properly and are often phased out or used in lower-grade products. In fact, most USB flash drive products use secondary particles, although they can meet the needs of normal use, but the service life may be short.
Let's go back to aigo AigoU357, the special point of this product is that it uses Good Die particles, which are basically not used in domestic brands in the 100 yuan price range. The use of this particle can ensure the stability and security of the data, and it is also helpful for the read and write speed, so users can use it more confidently.
Fourth, which one should be chosen by migrant workers, student parties, and self-employed people?
Here we will summarize first,The most important thing to choose a USB flash drive is to look at the demand point,After delineating the use scenario, then look at the price segment,The final overlapping part is the range we can buy。
aigo AigoLand U357 is a high-speed, large-capacity, U disk made of high-end flash memory particles is generally suitable for company employees and scientific research units, and can be used to store important company data, designers' original drawings and manuscripts, customer video clip DEMO or related PDF files, contracts, etc. And because of its higher data transfer efficiency, larger storage space, and better quality flash memory particles, it is more convenient and secure to store these important data. In addition, it is also a dual-interface design, which can be used by mobile phones and computers, and it is much more convenient to copy each other without the need for a network.
aigoU357 is the fastest standard speed in the current product brand, and the price segment is only about 100 yuan, whether it is a working person, or a student party, can afford it. The frequency of use of USB flash drives is so high, it is best to choose a high-quality one.
5. Why does the USB flash drive I bought get hot?
The above points are the most critical part of choosing a USB flash drive, and then there are some things about the user experience, such as the temperature of the USB flash drive when in use, multi-interface settings, appearance materials, etc.
Everyone knows that the U disk will heat up when reading data, and under normal circumstances, the U disk will have a slight heating phenomenon during use, which is a normal phenomenon. However, if the USB flash drive heats up excessively, it may mean that there is a problem. For example, excessive heating of the USB flash drive may cause damage to the internal electronic components, resulting in data loss; long-term exposure to high temperature will accelerate the aging of the internal components of the USB flash drive, thereby shortening the service life of the USB flash drive; excessive heating of the USB flash drive may lead to deformation of the shell and even cause safety accidents such as fire.
Excellent qualityU disk,The heat generated when used is limited,Let's also take aigoPatriotU357 as an example,Because the main control chip and particles used are top-notch,The temperature control effect is excellent,So the surface is only warm for a long time,Don't worry about a series of problems caused by overheating of the U disk。
In addition, aigo AigoU357 is still very intimate when designing products, dual interface design, push and pull switches on the side to both sides, you can launch standard USB Type-A interfaces respectively, and mobile devices are widely equipped with USB Type-C interfaces, so that you can transfer and back up data between computers, mobile phones, tablets and other devices. This design is more convenient and efficient for users who want to transfer a large number of files between tablets, computers, and mobile phones.
Since its release in 1995, the USB interface has undergone several iterations and upgrades. From the original 1.1 version to the later 2.0, 3.0, 3.1, and now the 3.2 version, each advancement has brought an increase in transfer speed and an improvement in the user experience.
aigo AigoLand U357U disk, as a product that reaches the USB3.2 Gen1 bandwidth ceiling, shows the deep accumulation of the aigo brand in the field of storage and the continuous pursuit of technology. The launch of this USB flash drive not only proves the great potential of USB3.2 Gen1 under the existing hardware conditions, but also brings new vitality and competitiveness to the storage market.
aigo Aigo: U357 meets the needs of users for high-speed, large-capacity, portable storage devices, the launch of this product, not only demonstrates the innovation ability of the aigo brand, but also reflects its keen insight into the market and in-depth understanding of user needs, which is worth choosing.
