Removable hard disks have high transfer speeds and large capacities
Flash drive is a general term
The so-called "USB flash drive" is the codename of a flash drive that was released by Lanco a long time ago (1999)
Like "Patriot" in the case of Huaqi
So nothing else can be called "USB flash drive" except for the one from Lanco. "Patriot"
So, except for the flash drive of Lanco, no other flash drive can be called "USB flash drive"
"USB flash drive" is the registered code name of Lanco, other flash drives are not called "USB flash drive". code name, other flash drive and then called "U disk" is an infringement, but you have to be non-take shoulders called dragon robe, no one cares about you, after all, we are used to call
Look at the 17th Beijing Evening News, Lanxess has sued a U.S. company for infringement of the use of the word "USB flash drive". "What's the same thing? With all due respect, it's all about ignorance and self-righteousness!
Mobile hard disk
Mobile hard disk, as its name implies, is a storage product that emphasizes portability with a hard disk as the storage medium. The vast majority of mobile hard drives on the market today are based on standard hard drives, and only a small number of them are based on miniature hard drives (1.8-inch hard drives, etc.), but the price factor dictates that mainstream mobile hard drives are still based on standard notebook hard drives. Because the use of hard disk for storage medium system, so mobile hard disk in the data read and write mode and standard IDE hard disk is the same. Mobile hard disk mostly use USB, IEEE1394 and other transmission speed faster interface, can be higher speed and system for data transmission.
Characteristics of mobile hard disk:
Large capacity
Mobile hard disk can provide considerable storage capacity, is a kind of more cost-effective mobile storage products. In the current high-capacity "flash drive" price, can not be accepted by the user, while the mobile hard disk can be accepted by the user within the price range, to provide users with a larger storage capacity and good portability. The current market of mobile hard disk can provide 10GB, 20GB, 40GB capacity, to a certain extent to meet the needs of users.
High transfer speed
Mobile hard disk mostly adopts USB and IEEE1394 interface, which can provide high data transfer speed. However, the data transfer speed of the mobile hard disk is still somewhat limited by the interface speed, especially in the USB1.1 interface specification of the product, in the transmission of a larger amount of data, will test the user's patience. The USB 2.0 and IEEE1394 interfaces are much better.
Easy to use
Nowadays, PCs are basically equipped with a USB function, the motherboard can usually provide 2 to 8 USB ports, some monitors will also provide a USB adapter, USB interface has become a personal computer in the necessary interfaces. USB devices in the majority of versions of WINDOWS operating system, can be without the need to install the driver, with a real "plug and play". The USB port has become an essential part of the PC's hardware design.
Reliability Improvement
Data security has always been a major concern for mobile storage users, and an important criterion for people to measure the performance of such products. Mobile hard disk to high-speed, high-capacity, lightweight and convenient advantages to win the favor of many users, and the greater advantage lies in the security and reliability of its stored data. The structure of this type of hard disk and laptop hard disk is similar, mostly using silicon oxygen disk. This is a more robust and durable platter material than aluminum and magnetic, and has a larger storage capacity and better reliability, improving data integrity. Disk drives that use silicone as a material are characterized by smoother platters, effectively reducing the number of irregular platters that may affect data reliability and integrity, and higher platter hardness makes USB hard drives highly reliable.
