In this page, you can find the speed test results of USB 3.0 flash drives or disks, made by USBDeview utility. USB Flash Drive Speed Tests - VID = 346d, PID = 5678

Out of the box, these drives operate on the legacy USB 2.0 protocol. They are built for low-intensity data storage rather than heavy file-hosting operations. According to standard diagnostic community benchmarks, like those cataloged via the NirSoft USBDeview speed testing index , the standard baseline metrics for this identifier profile are modest: Average Speed Range 14 MB/s – 22 MB/s Sequential Write 4.5 MB/s – 8.0 MB/s Default File System How to Get the "Best" Performance from VID 346D PID 5678

Because the controller and flash memory used in these highly generic devices are built to be as inexpensive as possible, they have a higher failure rate than name-brand drives (like SanDisk, Kingston, or Samsung).

Before diving into the specifics of VID 346D and PID 5678, it is important to understand what these identifiers actually mean. According to USB specifications, every USB device must have a Vendor ID (VID) and a Product ID (PID) to distinguish it from other devices connected to the same host.
