[ About Real Capacity ]

Capacity flash memory products are usually shipped in accordance with 1MB = 1000KB, 1G = 1000MB computing, but the operating system using binary arithmetic 1MB = 1024KB, 1GB = 1024MB, so there are some differences between the display capacity and standard capacity memory products.

1GB = approximately 900MB-1GB
(USB2.0: Read Speed: 10MB/S Write Speed: 2MB/S)

8GB = approximately 7GB-8GB
(USB2.0: Read Speed: 10MB/S Write Speed: 3MB/S)

16GB = approximately 13GB-15GB
(USB2.0: Read Speed: 12MB/S Write Speed: 4MB/S)
(USB3.0: Read Speed: 50MB/S Write Speed: 10MB/S)

32GB = approximately 28GB-30GB
(USB2.0: Read Speed: 12MB/S Write Speed: 4.5MB/S)
(USB3.0: Read Speed: 60MB/S Write Speed: 15MB/S)

64GB = approximately 58GB-60GB
(USB2.0: Read Speed: 13MB/S Write Speed: 5MB/S)
(USB3.0: Read Speed: 60MB/S Write Speed: 15MB/S)

128GB = approximately 110GB-120GB
(USB2.0: Read Speed: 13MB/S Write Speed: 5MB/S)
(USB3.0: Read Speed: 70MB/S Write Speed: 20MB/S)

[ The difference between USB 2.0 and USB 3.0 ]

(1) Compatibility is different:

USB 2.0: The USB (Universal Serial Bus 2.0, Universal Serial Bus) interface has the characteristics of faster transmission speed, support for hot plugging and connection of multiple devices. Backward compatible with USB1.1.

USB 3.0: USB 3.0 is backward compatible standard, compatible with USB1.1 and USB2.0 standards, with the ease of use and plug-and-play function of traditional USB technology.

(2) The transmission speed is different:

USB2.0 transmission speed can reach a speed of 480Mbps.

In addition to the USB 3.0 specification being optimized for lower power consumption and higher protocol efficiency, USB 3.0 ports and cables enable backward compatibility, as well as support for future fiber optic transmission. The actual transfer rate of the ultra-high-speed interface is about 3.2Gbps (ie 320MB/S). The theoretical maximum rate is 5.0Gbps (ie 500MB/S).
