Overall, these drives are regarded as reliable, "no-frills" storage for basic document transfers but are frequently criticized for poor performance under heavy workloads. Performance Review
While advertised as USB 3.2 Gen 1 (up to 5Gbps), real-world benchmarks show significant performance bottlenecks:
Read Speeds: Respectable for the price, typically averaging between 70 MB/s and 110 MB/s.
Write Speeds: This is the drive's main weakness. While it may start at ~25 MB/s, it often throttles down to 6–12 MB/s once the internal buffer fills up.
Small File Handling: Reviewers from SSD-Tester note extremely poor "4K" values (0.01 MB/s), meaning it will struggle if you try to transfer thousands of tiny files or run an OS from it. Design & Build VID = 951 (Kingston Technology), PID = 1666

Internal Hardware: Often uses a Phison controller (e.g., PS2251-07) and TLC flash memory. Troubleshooting "Device Not Recognized"
If your computer shows this VID/PID but doesn't open the drive, try these steps:
Check Disk Management: In Windows, right-click the Start button and select Disk Management. If the drive appears as "Unallocated" or has no drive letter, right-click it to Assign a Drive Letter or create a New Simple Volume.
Driver Refresh: Open Device Manager, find the device under "Universal Serial Bus controllers," right-click it, and select Uninstall device. Unplug and replug the drive to force Windows to reinstall the generic mass storage driver. The VID 0951 and PID 1666 identifiers belong
Port Power: Try a different USB port, preferably one directly on the motherboard (back of a PC) rather than a front panel or hub, as these drives sometimes require more power than a hub can provide.
Hardware Health: If the drive shows up with 0MB capacity or "No Media," the internal controller or flash chip may have failed.

Common Internals: These drives often use Phison controllers (such as PS2251-07 or PS2251-03) and Toshiba TLC NAND flash memory. 2. Technical Specifications
NamingSystem USB VID and PID as a device identifier - FHIR specification
The USB Device ID VID 0951 PID 1666 identifies a series of Kingston Technology flash drives, most commonly the Kingston DataTraveler 100 G3 . Device Identification
The Vendor ID (VID) and Product ID (PID) are 16-bit numbers used by operating systems to find the correct drivers for a connected device. Vendor ID (VID) 0951: Kingston Technology.
Product ID (PID) 1666: DataTraveler 100 G3, G4, SE9 G2, 50, and Kyson models. Internal Hardware Specifications
While external branding varies, these devices share similar internal architectures according to DeviceHunt and technical forum reports:
When you plug a USB device into a computer, the operating system uses the VID and PID, among other descriptors, to identify the device and load the appropriate drivers. If the device is recognized, it will be listed in the device manager under the "Disk Drives" or sometimes under "Universal Serial Bus Controllers" with a specific name that can be further detailed by checking properties.

models. These hexadecimal codes—Vendor ID (VID) and Product ID (PID)—function as a digital fingerprint, allowing operating systems to identify the hardware and load the appropriate mass storage drivers. Understanding VID 0951 and PID 1666
Every USB device uses a unique VID/PID combination assigned by the USB Implementers Forum. VID 0951: This code is registered to Kingston Technology.

If you run lsusb on Linux or check Windows Device Manager → Details → Hardware Ids, you will see:
USB\VID_0951&PID_1666\...
Symptoms: You can copy files from the drive but cannot add or delete files. Cause: The NAND flash memory has reached its write-cycle limit, or the controller has entered a fail-safe mode. Solution: Unfortunately, for the PID_1666, this is often a hardware failure. There is no software fix. Back up your data immediately and replace the drive.
Older Kingston controllers (like the one in PID 1666) are vulnerable to BadUSB attacks. A malicious actor can reprogram the drive’s microcontroller to emulate a keyboard and inject keystrokes the moment it is plugged in. If you find a loose flash drive with this VID/PID in a parking lot, do not plug it into your computer. It could be a "USB drop attack" weapon.
0951:1666 = Kingston DataTraveler SE9 G2 / DT100 G3 (USB 2.0, slow but durable).
Based on the USB ID VID_0951&PID_1666, this device is a Kingston DataTraveler 100 G3 (DT100G3) USB 3.0 Flash Drive.
Here is a comprehensive review of this specific device.
The Vendor ID 0951 is registered with the USB Implementers Forum (USB-IF) and exclusively belongs to Kingston Technology Corporation, a leading manufacturer of memory products and flash storage solutions. When a USB device is connected, the OS reads this VID to know which vendor’s driver set or generic mass storage driver to attempt.
Over production cycles, Kingston sometimes used the same PID for slightly different casing designs (e.g., DT 101 G2, DT 108, or DT Micro). However, the core controller chip and driver requirements remain identical. If you see this ID, you are dealing with a legacy Kingston USB 2.0 flash drive, typically with a storage capacity between 4GB and 32GB.
