Lexar Professional Stick 6670

Yes, the Lexar Professional Stick 6670 utilizes a USB 3.2 Gen 2 interface, but it is fully backward compatible with older USB 3.0 and USB 2.0 ports. However, plugging it into a legacy port will bottleneck the drive, and you will not achieve its advertised 1050MB/s read speeds. To get the maximum performance, you need to plug it into a matching USB 3.2 Gen 2 port.

While engineered to provide read speeds up to 1050MB/s, real-world transfer speeds depend on your computer's hardware and the file sizes being moved. You will get the fastest results when transferring large video files from a high-end NVMe-based system. Write speeds are typically lower than read speeds, which is standard for high-performance flash drives.

The drive is built with a focus on durability and consistent performance, featuring a robust, solid-state design without any retracting parts. This makes it highly resistant to physical shocks and drops, which is crucial for photographers on the go. However, users should be careful with the exposed USB connector to prevent pocket lint buildup.

Because it utilizes high-speed NAND flash memory capable of 1050MB/s read speeds, the Lexar Professional Stick 6670 can generate noticeable heat during sustained large file transfers. The metal casing acts as a heat sink to help dissipate this thermal energy. It is completely normal for the drive to feel warm to the touch when moving gigabytes of 4K video footage.
