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.

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.

I have had the Sandisk Ultra Luxe 512GB version for a few years now with Ventoy on it and have been very pleased with it. I keep a cheap USB-C to USB-A attached to it and that lets me use it with my phone or on any computer.
Dude, if you’ve been using your last one for 12 years then you really really don’t care about any of these stats/benchmarks
Caring about these bench marks is how you find one to last another 12 years.
If he’s going to use the next one for 12 years he definitely cares about picking a good one.
Oh my god, thank you so much for this. I have always had the hardest time finding these exact same requirements, and this is perfect. All metal construction and coexisting with keys has always been a priority for me, but it seems like everyone is inexplicably fine with copping out by just dangling their data on this flimsy little string tied to a brittle plastic case and I cannot understand it.
I’m not currently looking for one at this exact moment, but I will be returning here when I am. You’re doing the lord’s work out here!
Thanks for doing this! I’ve been pretty happy with my Samsung bar, considering how durable it’s supposed to be, but it’s great to hear about other options.

This is comprehensive, and impressive. Good job. Saving this post for my next purchase.
Can you show how you filed down the samsung bar?
The sharp parts were on the side you plug into the computer, all the way around the lip but especially the corners.
I used a large steel file, but a smaller diamond file would work too I’m sure.
Simply rub the corners at a 45 degree angle with the file until it no longer hurts to touch. Go slowly and gently so you don’t bend it.
This is an awesome analysis. I need to make a plug for my favorite, the Kingston FCR-ML3C. Its a micro metal usbc /usbA micro SD card reader. I upgrade my Samsung micro SD in it every once in awhile for speed and space upgrades. It sits lovely on my ID badge (works on Keychain too) and it’s a Swiss army type device that will work on whatever type of data port comes my way. Have used it for years and simply love it.
I’m not surprised the Corsair is better - it looks like there’s a whole nvme drive in there.
My husband has had a metal USB stick that is shaped like a key and is very thin specifically for this purpose. I don’t know the brand as it’s not printed on it, but it’s lasted him a long time and I would assume it to win this contest by a landslide. Excellent analysis, very interesting!
For reference, it looks like this (not the same brand):
They are usually no-name brand swag items
Edit: And your picture is USB 2.0LaCie IAmAKey. No longer made. Current ones are made from aluminum and bend easily. Originals were stainless and rigid.
My 2006 one just died, and I’m so frustrated with the new ones. Fortunately they’re pretty cheap, so who cares.
I got that from my middle school. Mine is red.
It would win the “will it fit nicely on a keychain” by a landsline.
However I doubt it would suit OP’s needs as the contacts are exposed so durability may be suspect, and seeing as it is generic I doubt the performance is up to his standards.
The contacts were surprisingly robust. Mine just died, sadly.
New ones are crappy knockoffs, but they’re cheap enough.
Enshittification strikes again!
Why sell customer one thing when you can make it shittier and they have to buy it again?
That Kingston DataTraveller I have as well and it’s my ol’ reliable from at least 9 years ago. For some reason PCs put up a fuss with recognizing other people’s USBs at boot, I’ve never once had an issue with the Kingston.
It is true that it is slower but for a live distro, install and troubleshoot disk it does the job perfectly fine.
I’ve had DataTraveller sticks since the late 90s/early 00s. Never given me a problem.
For me I found that the lack of responsiveness when in the booted environment was problematic. I use stuff like GParted on Linux bootable USBs to manage partitions too.
Writing a new image to the stick was also really slow.
New sticks are £10 for 64GB, so I recommend giving one of the above a try and see if you get a better experience!
Wow, great work!
Due my own personal bad habits, I fear I wouldn’t see 12 years out of most of those because of the lack of caps. A lot of random stuff ends up in my pocket when I’m doing projects. Screws and other things that will not have happy fun times with bare type A pins.
You’d be surprised! That old USB key has gone through the washing machine several times by accident and survived.
Also, the gap on a usb stick is pretty small and the pins reach quite deep, so unless you’re dealing with M3’s or smaller I doubt that the screws will end up in there.
Yeah, I mostly deal in m3 screws for my projects which, I know from experience, do get caught in type-A plugs.
Fair enough. For what it’s worth, the Corsair GTX has a cap that stays on fairly well.
Good review, it reminds me of a Project Farm video. That guy reviews things very much from a practical use standpoint.
Every metal one I ever had has at somepoint had the board fall out of the housing and get lost. They never survive the keyring.
I had that happen with the Kingston at one point in its life. Can’t remember how it happened.
I was lucky and spotted it before I lost it. I super-glued it back in and it works fine!
This looks awesome. Posting so I can read it later - the Mbin mobile site absolutely butchers your table, and I feel like submitting a bug report~
Yeah I noticed on my app too. Using Markdown syntax but the table is quite wide so it’s hard to fit on a mobile screen. I’ve found that rotating my phone to landscape helps, at least on my app.
Very cool! Thanks for sharing.
Just a thought on random write: If you are using swap/page files, it may have more of an impact. Or if you are updating the system in place.
I have no clue whether updating by flashing a new system image would be treated as sequential or extracted randomly as individual files.When you boot from a USB, it’s usually read-only, so I figured random writes wouldn’t be super important.
I’m hoping that flashing a new image is mostly sequential, but I might do a quick test with Rufus if you’re interested.
