How to choose and buy Usb dish
With disk prices Kuangxiang USBU, this new portable storage has been more and more attention, U disk with security, stability, and good encryption, versatility, etc., U replaced floppy disk has become more and more computer user configuration options. However, U-disk market, flocked to hundreds of brand is not limited to, a casual count as many as there are hundreds. Some of the old brands such as Netac, Aigo, and so is still hot, was hot brands such as Ruben seems to disappear in an instant, replaced by a more medium and small brands in dispute. Strong IT industry, many companies have also joined the camp of U disk, for example, in the board and was a smash hit in the Metroplex area of optical storage, digital pioneer in the fashion industry so manufacturers have SONY launched its own brand of U disk products. Currently USBU plate competition has taken shape, the product is also being developed to diversify, but also provide users with a variety of options. As to the question how to choose, let us look at the following article.
We know, U disk is not high tech, nothing more than the flash memory chip, USB input and output control chip, which together with a few necessary circuits (of course also need a shell), but this does not mean that the quality is not important . A large number of brand-name manufacturers in the PCB (printed circuit board) and cut corners on small devices, this is bound to affect the stability of product use and service life. Therefore, the time of purchase or should choose a good reputation of the brand. For some "me too" companies blindly by "low-quality reserve price," the practice of occupying part of the market, consumers should keep enough sober.
Tips to buy a U disk storage stability test of inner strength
U disk is to use FLASH memory core components of particles, usually on the market FLASH U disk particles mainly Samsung, Toshiba, SANDISK, NEC, and several other brands of products, with Samsung's flash memory particles most widely used word of mouth also best. Therefore, U disk in the purchase of the brand before the product may wish to use the flash for an understanding of particles, try to choose a better brand reputation. To our knowledge, SANDISK brand U-disk flash basic use of their particles, other such patriots, Mita and other major vendors are selected Samsung's A-level flash memory particles, the quality should be more secure.
In addition to the internal flash memory U disk particles is the control chip and circuit design, and in the control chip and circuit design, well-known brands of products believed to be more excellent, and therefore job stability if compared to the U drive fancy, well-known brand products are the best choice.
U disk tips to buy two sturdy waterproof dust cover and ultimately,
Although U disk in a variety of computer products in just a little, but this can often bear little responsibility. Participate in the bidding tender, lecture speech out of this little man in the stomach filled with it. However, there are plenty of internal, but also that can not be sloppy appearance. U disk as a small child, often fell to the ground from his pocket would not pay attention to it if the case was not strong enough, which may kick in. Save the data. At this time, solid shell may come in handy. For example, Mita Poseidon latest nano Steel U disk to use nano-alloy steel shell, durable and also can play a role in maintaining health. Because in this new nano-materials in the nano-alloy steel can effectively play the role of antimicrobial sterilization, effective 95% of the surface of the U disk full kill the bacteria. Meanwhile, the Poseidon series of U disk products also have to JIS 4 JIS 8-class level and waterproof. JIS 4 waterproof Poseidon U disk is one of the popular fashion products, is waterproof spray type, for any direction of the droplets, not images of their work. To achieve the JIS 8 waterproof Poseidon U disk is a business-type high-end products that can work in the water, usually the pressure of the water at the designated use, it does not matter even if dropped in water, can dry out the normal work.
U disk also can not just buy the appearance, internal or external must have a clear look carefully, the blind pursuit of the appearance of small is not necessarily the product advantage, and the blind pursuit of low prices tend to make you regret to buy the product. Select the most suitable is the best, rich internal and external quality, high-quality U disk, etc. you buy!
Factors that affect the performance of flash drive
Bottom line PCB design and components of the welding process also have a greater impact overall product performance. Bottom line good PCB design in addition to help control the chip processing piles of data channels, also plays a variety of clutter "filter" of the role. This will extend the life of the control chip and FLASH have some help.
Mobile USB flash drive as PCB floor area is small, it is impossible to accommodate the capacitor as the capacitor on the motherboard graphics card as big, so much so the welding work in the capacitor need to compare carefully. Chip manufacturers are based on the regular machine welding machine, small factories are the workers out of hand soldering, the device is very neat paste. From here we can see, manufacturers work well or not will determine the stability of the product.
Flash drive packages also have an impact, flash drives currently on the market housing in two packages, one is fixed with screws, screw on the appearance of beauty. And sealing is not good. The other species are some of the direct use of ultrasonic wave machine manufacturers of ultrasonic welding seamless sealed, sealing the highest. And demanding process of the plant, a confidential hundreds of thousands of ultrasonic wave, the general process of small factories can not be achieved, using ultrasonic welding seamless package out of the flash drive and long service life, moisture and vibration resistance are also prominent on the performance .
Flash drive shell is not just related to appearance. The flash drive chip, the external environment is very sensitive to static electricity, the slightest mistake can easily cause the chip burned, so the shell material selection, design, are very particular about things.
In addition, in vitro exposed to the flash drive USB interface, because I often plug, can easily cause hardware damage, so that the security of stored data is greatly reduced. So here is a very important link. In fact, the life of many flash drives often planted in the USB interface. Better USB interface standard chrome thickness over 0.02mm, hardness of 900, more than 400 per cm high number of micro-cracks, wear resistance was greatly enhanced, from the appearance of fine light. The USB interface, the less it is easy to use after a period of "loose" out, because the USB interface circuit contacts are not tight against the flash memory power can not be erased, so the flash drive to this most likely scrapped. Therefore, we in the purchase of flash drives have to try it when the interface is standard, tight little more better. With the appearance of work can be seen.
