Background
I have had the same Kingston DataTraveller DTSE9 since around 2010, when I was still in school. I've carried it on my keychain for at least 12 years and it still works, its "the old reliable".
That said, it's slow. Very slow. I use it mostly as a boot USB for Linux / Windows, so I need several sticks with decent random read speed, and decent write speed for when I update them.
My criteria were:
- All-metal construction for durability, including the keychain loop
- Sits well on a keychain next to keys
- Reasonable speed, including random reads.
Testing method
I evaluated the sticks in two ways.
I ran CrystalDiskMark with 256 MiB (x5) configuration.
I also measured the angle at which the USB stick sits on a keyring. I found that several of them could not sit perpendicular to a keyring it because of their geometry, which makes it difficult to comfortably use them next to keys.
At the datum of 0 degrees, the key sits perpendicular to the keyring.

Here are the 6 main competitors in this space I bought.

Some additional notes:
- The Samsung Bar had really sharp corners. You might need to file them down like I did.
- Corsair GTX: the 128GB version is no longer available and the lowest capacity is 256GB. It's more of a portable SSD in the form of a USB stick, which makes it really fast, but it's bulkier than a normal USB stick, though not by much. Often it takes up more than one USB port because it's wide. It's still very good and I recommend it.
Other devices
Some related products I own but don't qualify for this comparison but are offered up here for context.
Here's why they don't qualify.
-
Crucial P3 Plus: It's an NVME SSD. Can be made portable with a good enclosure, but too bulky for what I'm looking for.
-
Samsung 860 Evo: It's a SATA SSD, definitely not the right form factor.
-
Sandisk Ultra Curve: I bought this thinking it was made out of metal, but it was not. It's fairly flimsy plastic.
-
Kingston DTSE9 16GB: This is my old stick. The old reliable. No longer sold, but I've tested its successor.
-
Samsung SD Card: It's a 2016 MicroSD card connected to my PC via a MicroSD-SD adapter and a USB card reader. I included this as a meme.

Conclusion
There are no clear winners in this fight.
- The Corsair GTX is the fastest in all categories by a country mile, but has a larger form-factor than other entries and higher price. Very good, but not for everyone.
- Samsung Bar has the fastest random writes, and decent performance in other metrics for its USB stick form factor, but sits awful on a keychain due to the angled hole.
- The Integral Arc 3 has solid random performance, but worst sequential performance than the rest.
- Sandisk Ultra Luxe gets the best overall balance of performance, but does not sit on the keychain super well.
- The two Kingston's perform effectively the same, with the Micro being much more compact. That said, that can be a disadvantage on a keyring if there are adjacent items.
- All competitors (bar the GTX) had similar random reads.
For me, I'd say the right choice is either the Kingston DTSE9G3. It's a nice upgrade over my old DTSE9 and sits nicely next to it's grandfather. If I needed any random writes though, for copying lots of small documents like code files, I'd pick the Integral Arc 3.
8GB in 2007?! How much did that cost?
Still have the 4GB version of this one somewhere. Bought in the same year
Served be well over the years
Mine has been relegated to BIOS updates, still doing a great job just a bit small these days.
Shit I had one of those. Now I'm feeling all nostalgic remembering fidgetting with the slider
Still have this same usb stick and it works flawlessly
That’s the highest Scoville rating I’ve seen on a USB stick
I bought 2, probably around the same time. One of them failed after years of serving as my NAS boot drive, so I replaced it with its twin, and that one is still going strong.
had a bunch of these, the ones with U3 partitions were super hack tools, could autorun apps and scripts like a CD, windows didn't know wtf to do.
