USB 3.2 Gen1? USB 3.2 Gen2x2? Can’t tell the difference between USB types?

The USB Implementers Forum (USB-IF) has revised its naming conventions for USB technologies to address the confusion caused by the previous naming system. The new system is more straightforward, focusing on the data transfer speed of the USB technology rather than using generation numbers and “SuperSpeed” designations. For example, what was once referred to as USB 3.2 Gen 1×1 is now simply USB 5Gbps and USB 3.2 Gen 2×2 has become USB 20Gbps. This change aims to make it easier for consumers and professionals to understand and differentiate between the various USB technologies based on their performance capabilities. Despite the shift to this simpler naming system, some of the older naming conventions may still be used in the market.

USB-C 20Gbps | Samsung T9 mobile solid-state drive performance and temperature measurement

When using the Samsung T9 SSD with its USB-C 20Gbps interface, it’s important to note that lower-end computers with Type-C ports may only support 5Gbps or 10Gbps. This means they won’t be able to fully utilize the T9’s performance capabilities. To achieve the best performance, the T9 should be connected to a port that supports 20Gbps or higher. In your test setup, you’ve used an Intel i9-14900K platform and connected the T9 to a USB 3.2 Gen 2×2 Type-C port on an ASUS ROG Strix Z790-A GAMING WIFI II motherboard, which is ideal for maximizing the potential of the T9. Your configuration also includes high-speed components like DDR5 memory and high-capacity storage, ensuring a robust testing environment for the T9’s capabilities.

System information.

Using CrystalDiskInfo to view the SSD information reveals that the Samsung T9 supports the UASP (USB Attached SCSI Protocol) interface. This protocol enhances data transfer speed by allowing multiple commands to be processed in parallel. The UASP reduces CPU usage, latency, and waiting times during data transfer, contributing to more efficient and faster performance compared to traditional USB mass-storage bulk-only transport. This capability is particularly beneficial for tasks involving large file transfers and intensive data operations.


The performance test results of the Samsung T9 SSD using CrystalDiskMark with default settings indicate impressive speeds.
