Kingston DataTraveler Kyson 256 GB — Capless Metal, 200 MB/s

Up to 200 MB/s read60 MB/s writeCapless metal, 4 g256 GB

The Kingston DataTraveler Kyson (DTKN/256GB) is a 256 GB USB 3.2 Gen 1 flash drive in a capless metal body weighing four grams, rated at up to 200 MB/s read and 60 MB/s write. It is built around a keyring loop, so it is the drive that lives on your keys and still moves a quarter of a terabyte at a usable speed.

Compatibility — check before buying:
USB Type-A only — it will not plug into a phone or a USB-C-only laptop without an adapter, and none is included. Worth knowing before you standardise on it: Kingston lists Windows 11 and 10, macOS 10.15 or later, Linux 4.4.x or later and ChromeOS, which is broader legacy support than several of its current drives. The write figure of 60 MB/s applies to the 128 GB, 256 GB and 512 GB models; Kingston publishes no write speed for the 64 GB at all, so if you compare capacities, that is why the smallest one looks different.

Best For

✓ A keyring drive that carries real capacity
✓ Moving photo and video sets between machines
✓ Handing a project archive to a colleague
✓ Machines still running Windows 10 or older macOS
✓ Anyone who wants both speeds published
✓ People who lose caps within a week

Key Features

 
Four grams, all metal
39 x 12.6 x 4.9 mm and 4 g — the lightest drive in this listing by a clear margin. The casing is metal with no cap, no hinge and no moving parts, which is exactly what survives life on a keyring.
 
A keyring loop Kingston actually publishes
Kingston lists a functional loop for attaching to key rings as a specification rather than a marketing line. That distinction matters: several drives in this class only imply a keyring in their photographs.
 
200 MB/s read and 60 MB/s write
Both figures are published. Kingston gives 200 MB/s read across 64 GB to 512 GB, and 60 MB/s write for the 128 GB to 512 GB band that includes this 256 GB model. A 10 GB folder reads off in under a minute and writes on in around three.
 
Broad operating system support
Windows 11 and 10, macOS 10.15 or later, Linux 4.4.x or later and ChromeOS. No drivers, no software, and an operating range of 0 to 60 °C with storage down to −20 °C.

Frequently Asked Questions

Is 60 MB/s write enough?
It depends on the direction of your work. Reading at 200 MB/s is quick; writing 10 GB onto the drive takes roughly three minutes, and filling all 256 GB from empty takes a little over an hour. For carrying a library and handing files over, that is comfortable. For emptying a camera card onto the drive every evening, a drive with a higher published write figure will feel different.
Will it survive a keyring?
That is what it is designed for. The body is metal, there is no cap to lose and no hinge to snap, and Kingston publishes the key-ring loop as a specification. Four grams also means it does not swing hard against a laptop when plugged in and knocked.
Does it work on older Macs and Linux machines?
Yes, and this is one of the Kyson’s quiet advantages. Kingston lists macOS 10.15 or later and Linux 4.4.x or later, along with Windows 11 and 10 — wider than several newer Kingston drives which require Windows 11 and macOS 13 or later.
What fits in 256 GB?
Around 50 hours of 1080p video at typical bitrates, roughly 8,000 24-megapixel RAW photos, or a large document archive several times over. Formatted capacity always comes out a little below the stated figure.
Singular Expert Insight
The Kyson is the drive to reach for when the requirement is simple: metal, capless, on a keyring, with both speeds in writing. At 4 g it is lighter than any other drive on this page, and 200 MB/s read with 60 MB/s write puts it well ahead of the plastic sticks without pushing into portable-SSD prices. It also supports a wider range of systems than Kingston’s newest models, which still matters in an office with mixed machines. One thing worth being aware of if you are choosing a long-term standard: Kingston’s own consumer listing now promotes the Exodia S and Exodia M as its headline personal drives, and both of those are capped designs. If what you specifically want is a capless metal drive, the Kyson and the DataTraveler SE9 G3 are the two to compare, and the SE9 G3 is the faster of them at 220 / 100 MB/s.

Buyer’s Guide

Buy it if

You want a metal, capless keyring drive with both speeds published, 256 GB of space, and support for older macOS and Linux machines alongside Windows.

Skip it if

You copy large files onto the drive constantly — 60 MB/s write is respectable rather than fast. Skip it too if you need USB-C, hardware encryption, or a rugged rating.

Also consider

Kingston DataTraveler SE9 G3 256 GB for 220 MB/s read and 100 MB/s write in a similar metal body. Kingston DataTraveler Micro 256 GB if you want the smallest possible drive to leave in a port. Kingston IronKey Locker+ 50 G2 if the contents need encrypting.
