: Generic drives often show a capacity (like 4GB) that is larger than the actual usable space (often around 3.7GB). This is due to the way manufacturers calculate gigabytes versus how your computer reads them 0.5.1.
To find the "best" version of this product, you must validate the hardware. Here is a step-by-step guide used by hardware enthusiasts:
If you recently bought a cheap drive with this hardware ID that gives you read errors after copying a few gigabytes of data, run a verification test using Fight Flash Fraud (F3X) on macOS/Linux or on Windows. These tools write sequential dummy data to expose the true physical capacity of the drive. If you need help optimizing your drive, tell me: What total capacity is the drive currently showing?

Data corruption, disappearing files, or "The disk is not formatted" errors are common with lowβquality flash drives and counterfeit drives.
While the VID/PID combination itself is consistent, the physical devices that carry these identifiers come from several different brands and configurations:
: Typically slow USB 2.0 speeds, with writes averaging ~3MB/s and reads near ~25-30MB/s. Form Factor : Generic drives often show a capacity (like

Typically range between 15 MB/Sec and 25 MB/Sec . Here is a step-by-step guide used by hardware
However, actual speed tests submitted to the USB 3.0 Flash Drive Speed Tests database reveal a massive disparity in performance. The read and write speeds (measured in MB/Sec) vary wildly from device to device, largely depending on the memory chip quality and the port used. In a Chinese tech forum, a user asked, "Is this speed normal?" for their VID 346D drive. The response from the community was unanimous: "Abnormal. Completely abnormal... the controller is bad."
Be aware that these generic drives often use controllers like the FirstChip FC1178BC . If the drive shows a lower capacity than advertised (e.g., 3.7GB for a 4GB drive), this is standard overhead, though these IDs are sometimes associated with "fake capacity" drives that require verification with tools like H2testw . 2. Best Drivers for VID 346D PID 5678
If you are in the market for a USB drive and have encountered the VID 346D, PID 5678 identifier, you are likely trying to determine whether this device is "the best" for your specific use case.
