Unidade flash USB 2.0 em formato de cartão de metal

Craftsmanship and Materials

The card shaped USB 2.0 flash drive is made of metal and processed through elaborate techniques such as wire drawing and oxidation.

This gives it a fine texture, excellent wear – resistance, and drop – resistance, effectively protecting the internal storage chip. Compared with plastic materials, the metal shell not only enhances the product’s grade but also improves its durability. It is less likely to get scratched or deformed during long – term use.

Interface and Transfer Speed

Equipped with a USB 2.0 interface, it features a mature and stable transmission protocol, widely compatible with various devices, eliminating concerns about interface compatibility issues. Its theoretical transmission rate is 480Mbps. In actual use, the read speed is approximately 15 – 25MB/s, and the write speed is around 5 – 15MB/s. Compared with USB 3.0 (with a theoretical rate of 5Gbps and an actual read speed of up to 40 – 100MB/s), USB 2.0 is slightly slower. However, it has stronger compatibility and a lower cost. It can fully meet the needs of daily data transfer, such as small – capacity documents and photos, and can also work stably on older devices.

The USB flash drive adopts a hidden – interface design. The interface can be flexibly popped out and retracted. When retracted, it integrates with the card – shaped body, protecting the interface from damage and making the overall appearance more concise and regular. It is as convenient to carry as a metal card and can be easily placed in a wallet or business – card holder.

Metal cards in multiple colors can be customized, such as classic black, stylish silver, vibrant red, and fresh blue, to meet different aesthetic and brand – color requirements.

Logos can also be customized. Whether it’s a corporate brand logo, an event – specific symbol, or a personal creative pattern, it can be precisely presented.

Laser Engraving: High – energy laser beams are used to engrave patterns and text on the metal surface. It offers high precision and clear lines. The logos and patterns have good wear – resistance, are not prone to fading or abrasion during long – term use, and can maintain the customized effect for a long time. It is suitable for presenting simple and refined designs.

Silk – Screen Printing: Ink is printed onto the metal surface through a silk screen. This process can achieve rich – colored and complex pattern printing, with strong color expressiveness. It can present gradient and multi – color splicing effects, making the customized content more vivid and colorful. It is suitable for making large – area and colorful logos and patterns.

Anodizing and Coloring: An oxide film is formed on the metal surface first, and then coloring is carried out. The color is uniform, with strong adhesion. The customized color is long – lasting and stable. It can also enhance the hardness and wear – resistance of the metal surface, making the customized metal – card – shaped USB flash drive both beautiful and durable.

The metal card shaped USB 2.0 flash drive has a relatively high cost – performance ratio.

From a cost perspective, although the metal material and elaborate craftsmanship make its cost slightly higher than that of plastic card – shaped USB flash drives of the same type, its durability is greatly improved, reducing the replacement cost caused by device damage.

In terms of functions and customization, while meeting daily data storage needs, it provides rich customization options. When used by enterprises for brand promotion, customized USB flash drives with logos, taking advantage of their practical storage function, can remain in the hands of users for a long time, achieving continuous brand exposure. The promotional cost is low, and the effect is long – lasting.
