Mobile hard disk
Mobile hard disks use hard disks as storage media. Computers exchange large-capacity data and emphasize portability.
SSD Solid State Drive
A hard disk made of a solid-state electronic memory chip array is composed of a control unit and a storage unit (FLASH chip, DRAM chip). It has the characteristics of fast reading and writing, light weight, low energy consumption and small size that traditional mechanical hard disks do not have.
The universal serial bus is a serial bus standard that connects computer systems with external devices. It is also a technical specification of input and output interfaces. It is widely used in information communication products such as personal computers and mobile devices.
USB 3.0, a new generation of USB interface, is characterized by a very fast transfer rate, which can theoretically reach 5Gbps, which is 10 times faster than USB 2.0. The appearance is basically the same as the ordinary USB interface, and it is compatible with USB 2.0 and USB 1.1 devices.
Hard disk cache provides high-speed data buffering for the reading and writing of mechanical hard disks. The larger cache capacity can greatly improve the burst read and write speed of mechanical hard disks, especially when the mechanical hard disks need to frequently modify data, it can maximize its performance and greatly increase the life of mechanical hard disks.
The full name of e-SATA is External Serial ATA (External Serial ATA), which is an external expansion specification for the SATA interface. e-SATA is an "external" version of SATA, which is used to connect external rather than internal SATA devices.
Thunderbolt Thunderbolt interface
Thunderbolt connection technology combines PCI Express data transmission technology and Display Port display technology, which can simultaneously transmit data and video signals, and each channel provides bidirectional 10Gbps bandwidth.
Encrypted mobile hard drive
The encrypted mobile hard disk uses a 32-bit high-speed encryption chip to install a secure door for the mobile hard disk. Before using the encrypted mobile hard disk, you need a password to verify the login. If you enter the wrong password 5 times in a row, the password and key information in the encrypted mobile hard disk will be automatically destroyed.
