As technology continues to advance, so do the interfaces to external devices in computers. Inserting a USB flash drive on a computer is a common operation, but there are various standards for USB flash drive interfaces. This article will analyze the common interface standards when plugging in a USB flash drive on a computer to help readers better understand and choose a USB flash drive that suits their needs.
Demo environment: Honor MagicBook 16 Pro, Windows 10
usb 2.0：
usb 2.0 is an older USB standard with transfer speeds of up to 480 Mbps. Its interface is usually a rectangular socket and is widely used on a variety of computers and devices. usb 2.The USB flash drive with 0 interface is suitable for general data transmission needs and is the main connection method for many older models of computers and devices.
usb 3.0：
usb 3.0 is an upgraded version of the USB standard, and the transfer speed is faster than USB 20 is faster, up to 5 Gbps. usb 3.The 0 connector is usually blue and can be backwards compatible with USB 20 devices. Most modern computers and devices are equipped with USB 30 interface, which provides faster data transfer speeds, making it one of the most common connection standards for USB flash drives.
usb-c：
USB-C is a new generation of USB interface, which is gradually becoming popular in various devices. It has a reversible design and can be connected on either side of the socket. The USB-C interface supports USB 31 and later, the transmission speed can reach more than 10 Gbps, with multi-functions such as charging and ** output, and has become one of the mainstream interfaces for computers and devices in the future.
The Thunderbolt connector can transmit multiple signals such as data, **, and power through the same interface. Thunderbolt 3 uses a USB-C physical interface and supports extremely high transfer speeds of 40 Gbps. When large-scale data transfer is required or when connecting an external high-resolution display, the Thunderbolt interface becomes a powerful choice.
The External Serial ATA (External Serial ATA) interface is a standard SATA interface designed for external device connections. Its transfer speed can reach 3 Gbps, relative to USB 20 is faster.
The eSATA interface is typically used to connect external hard drives and other devices that require high-speed data transfer. However, thanks to USB 3With the advent of 0 and thunderbolt, the eSATA interface was gradually eliminated.
MicroUSB and miniUSB interfaces are smaller-sized USB interface standards that are widely used to connect cameras, mobile phones, and other small devices. They are often used in early USB sticks and some specific mobile devices.
1、usb 3.0 and above: If your computer supports USB 30 and above, select the USB flash drive of the corresponding interface to obtain faster data transmission speed.
2. USB-C: If your device supports the USB-C interface, especially on the new generation of computers and mobile devices, choosing a USB flash drive with the USB-C interface will provide a better connection experience and performance.
3. Choose Thunderbolt according to your needs: If you need higher data transfer speeds and versatility, consider using a USB flash drive that supports the Thunderbolt interface.
4. Consider device compatibility: When choosing a USB flash drive, make sure its interface is compatible with the interface of your computer or other devices to ensure normal use.
Overall, the USB interface is currently the most widely used and most compatible USB flash drive connection standard. With the advancement of technology, new interface standards are constantly emerging, and users can choose the USB flash drive that suits them according to the needs and compatibility of the device.
