The best USB flash drives: which model to choose?
USB flash drives have become essential peripherals for data transfer and temporary or permanent document storage. Thanks to their flash memory, they offer ever-increasing storage space, while retaining a compact, practical format. Well-known brands such as Western Digital and Verbatim offer high-capacity models with high transfer speeds.
Before you buy, check the connectivity: some drives require an adapter (e.g. USB Type-C to USB Type-A) to be compatible with your computer. Under Windows, it’ s advisable to format the key in NTFS if you plan to handle large files or make regular back-ups. You can also create a dedicated partition if you intend to separate different types of data.
It’s also important to choose a model with a good transfer rate, to save time when copying large files. Finally, don’t forget to plug in your key correctly and check its performance regularly: a good internal controller indirectly contributes to greater reliability and stable speed.
The Kingston DataTraveler Max is considered the world’s best USB flash drive in November 2025 thanks to its exceptional performance. With read speeds of up to 1,000 MB/s and write speeds of up to 900 MB/s, it takes full advantage of USB 3.2 Gen 2 to deliver ultra-fast transfers of large files. Available in USB-C or USB-A versions, it fits all modern devices. Its compact design with sliding connector protects your data on the move. For professional or multimedia use, the Kingston DataTraveler Max will be very fast. Available in capacities up to 1TB, it’s almost as big as an external drive. It’s a must-have choice for those looking for the best USB flash drive on the market.
What is the current standard for USB flash drives in November 2025?
the most common standard in 2025 is USB 3.2 Gen 2×2, which allows theoretical speeds of up to 20 Gbps.
This standard is often used in high-performance USB stick models, but the majority of consumer USB sticks still work with USB 2.0 (which is really slow).
The latest USB standard is USB4 version 2.0, which supports transfer speeds of up to 80 Gbps in both directions. This new advance uses USB-C connectors.
