U disk purchase skills and precautions

Due to the increasing demand for data exchange capacity, various mobile storage devices emerge. With the advantages of large storage capacity, easy to carry and large transmission rate, USB disk and mobile hard disk have increasingly entered the life of the majority of users and have been more and more widely used
1. Purchase precautions Among the many USB disk brands, how to choose a USB disk that speaks to your needs? Below we will take a look at the USB disk product purchase precautions for user reference.
From the basic type of USB flash drive to set the purchase point of view at present, the USB flash drive products on the market are numerous, the performance is weak, the function is also different. On the whole, the current USB drive products are mainly divided into different types such as no-drive, encryption, double start and start high-speed, and on this basis, the capacity is subdivided to provide specific products with different capacities. Different types of USB disk products reflect their different performance characteristics and provide different functional services.
The no-drive model was an earlier flash drive product. The performance highlights the advantage of convenient and quick use of USB disk. For example, in the system state of Windows 2000/ME/XP, the USB flash drive can be directly inserted into the USB interface to achieve the true "plug and play". However, no driver is not absolute, because the Windows 98 system itself does not have a built-in Storage driver, so you must use the USB drive to install the driver before use. This is also the technical constraints that no-drive products have not been able to break through so far, so that the development space of this type of USB disk products is reduced.
Encrypted USB flash drive is a product designed and launched to meet the needs of users to protect their privacy. It through the hardware flash drive lock and data encryption preservation technology, better strengthen the privacy of the data, thus, the encrypted flash drive not only has all the functional characteristics of the original other types of flash drive products, but also enhances the security and confidentiality of the stored data. The data is first stored in the flash drive after specific encryption, and the data needs to be decrypted before it can be extracted from the flash drive, which further ensures the security of the data in the flash drive and realizes the "confidentiality" of some office users and business users. Therefore, once this type of product was launched, it was loved by a considerable number of everyone users
Dual boot USB flash drive is mainly designed for USB-FDD/HDD dual BIOS boot mode and mobile storage products, this kind of product launch time is not long, is considered to be an ideal alternative to the traditional floppy disk and floppy drive solution products. With the new round of technological upgrading of traditional PCS and laptops, the market potential of this USB drive will also grow and will become the main product of the USB drive market.
In fact, the difference between the type of USB flash drive is to compare the differences in their respective performance characteristics, consumers in the purchase, you can decide what kind of USB flash drive products to buy according to their preference for which aspect of performance. For example, users who want to store data in "absolute privacy" are naturally best to buy encrypted USB drives, while consumers who want to improve storage speed can only be satisfied by buying high-speed products. There are a wide variety of USB products, and the performance is relatively complete, not afraid that you can't choose the products that meet your needs, but you are afraid to cross your eyes and forget what kind of performance services you want to get.
Clearly understand their own use, so as to locate the scope of purchase
Not only are there many types of flash drives, but the capacity of the same type of product is also different, and the capacity has become a determining factor in the price of flash drives. At present, the flash drive capacity is mainly divided into 16MB, 32MB, 64MB, 128MB, 256MB, 512MB1GB 7 grades, the larger the capacity of the higher the price, the price from low to high or even a difference of 10,000 yuan.
Therefore, before buying a flash drive, it is best to make a simple positioning for your own use and avoid blind purchases.
If you are a student or just an ordinary individual user, the purchase of flash disk is only used for general documents, picture storage transfer, MP3 or other audio and video file download, then the price is not high enough function of low-end products worth considering, and strive to achieve the best purchase results of cheap. The purchase specifications of the office family are relatively high, because the amount of data that needs to be stored is large, so the capacity and data transmission speed requirements of the flash drive are correspondingly increased. Popular USB disk products should not be within the scope of purchase, instead, more attention should be paid to those high-end mainstream products with comprehensive performance. Large capacity, fast data transfer speed of those USB disk products can be fully competent for ordinary office needs and general business activities.
Choose mainstream brands to avoid quality troubles
If the concept of the type of flash drive product is vague, and the main use of the flash drive can not be clearly positioned, then it is best to pay attention to the mainstream brand products on the market when buying flash drive, because at this time the brand is a guarantee of quality
Now on the market of flash drive manufacturers led by Lang Ke, Huaqi, etc., these broad business involved in the flash drive market for a long time, to form a complete research and development, market investment and after-sales service system, for consumers is a more assured choice target.
