Kingston DataTraveler SE9 Review: Durable Everyday Carry Verdict
What stood out the most was how many people still carry a Kingston DataTraveler SE9 USB Flash Drive on their keychains years after buying it—often scarred, scratched, even washed—yet it keeps working. Across platforms, its minimalist all‑metal casing and pocket-size form factor consistently earn praise for blending portability and durability. However, speed results and vendor reliability vary sharply, landing this drive at 8.2/10 in overall user sentiment.

Claims vs Reality
Kingston markets the SE9 G3 as hitting “220 MB/s read and 100 MB/s write” and being a “premium‑style storage solution” for USB Type‑A devices. In controlled lab conditions, that’s achievable with certain capacities—but digging into reports reveals inconsistencies.
While officially rated at 100 MB/s write, Reddit user Ant*** noted receiving a 64 GB unit with “30 MB/s write instead of 60 MB/s… 200 MB/s on read is correct, but random file speeds are less impressive.” Similarly, a Yandex Market buyer described copying a 1.4 GB video at “14.5–15 MB/s… maybe my old PC or USB 3.0 port isn’t optimal,” highlighting how setup impacts real-world throughput.
The durability claim fares much better. Reddit users recount years of abuse: “I have never had one of these die on me… 4 years on my keychain,” while a Trustpilot reviewer detailed multiple drops “in water, showered, or accidentally washed… still works.” This aligns with Kingston’s metal-casing durability pitch.
As for “premium style,” aesthetics are indeed a hit—many users post it hanging alongside house keys, with one calling the golden finish “minimalist… in such a case even driving over it wouldn’t scare me.”
Cross-Platform Consensus
Universally Praised
Portability is the SE9’s signature. A verified Amazon buyer said: “It’s tiny and fits on a keychain so you’ll never forget it… sleek, small and fits right on my key chain.” IT professionals mention it as an always‑with‑you tool; Reddit user u/sysadmin*** carries essential drivers so he isn’t scrambling to re‑download in the field.
Durability stories span years and continents. A Trustpilot report: “Handles everyday use and being on my car keys… even thrown in a pool and it still works.” This ruggedness makes it appealing to travelers, field workers, and students—buyers repeatedly mention storing OS installers, films, or project files and trusting it to boot systems on the go.
Aesthetic appeal also transcends platforms. Minimalist design has fans among “design nerd colleagues who drool over this little thing,” said one Amazon reviewer. Its unobstructed port design lets it slip into recessed USB slots where bulkier drives fail.
Common Complaints
Speed is the recurring frustration. One Yandex Market reviewer transferring “Avatar in 4K” via USB 2.0 saw 104 GB take “about an hour and a half,” while write performance for smaller models can drop into mid‑teens MB/s. Older SE9 USB 2.0 variants perform even lower, with Trustpilot quotes averaging “6.8 MB/s write” and “16.1 MB/s read”—fine for documents, slow for video archives.
Heat build-up is noted by multiple owners. A Russian buyer observed the drive “growing warm not only when working but just plugged into a TV box in standby.”
The tiny form factor creates its own issue: misplacement risk. “Very small and easy to lose but the loop allows you to keep it on a keychain,” cautioned one reviewer. Lack of a dust cap means exposed contacts—minor for office use, more problematic in dirty environments.
Vendor reliability concerns also surface. Trustpilot entries describe receiving USB 2.0 instead of USB 3.0 versions, mislabeled packaging, or outright counterfeit “1 TB” units that didn’t work. One buyer’s files “magically disappeared” on a wrong‑model SE9 sent in place of their order.
Divisive Features
Heat and speed balance is divisive: some say temperature rise is negligible; others find it warm enough to worry. Speed perceptions vary—buyers transferring small documents are satisfied (“speed is decent”), but video editors or OS installers sometimes report bottlenecks.
The absence of a protective cap splits opinion. Minimalist enthusiasts like the clean, capless design; others in trades or outdoor work prefer sealed connectors.
Capacity options (up to 512 GB) thrill heavy media users, but smaller sizes remain popular with IT pros prioritizing OS installs over bulk storage.
Trust & Reliability
Scam or mix-up experiences primarily involve third‑party sellers. On Trustpilot, several buyers warn about “obvious fakes” or wrong-generation models shipped with tampered barcodes. Positive resolutions often involve swift refunds rather than replacement reliability.
Long-term users praise genuine units. One Amazon buyer wrote: “Bought this baby back in 2015… after 3 years of falling and scratching it still works great,” while another kept a SE9 on their keychain for “over four years” without failure. Kingston’s 5‑year warranty offers reassurance, though vendor choice is key to avoiding counterfeit risks.
Alternatives
Competitors mentioned include SanDisk’s line, with one Amazon comment stating, “I would recommend the SanDisk line” for faster write speeds. However, many SE9 fans overlook speed in favor of durability and aesthetics, noting plastic-cased rivals can crack or warp under keychain stress.
Price & Value
On eBay, brand-new SE9 G3 models span roughly $9.47 for 64 GB to $45.94 for 512 GB, with occasional bulk discounts. Market prices trend stable, and resale value is modest given their ubiquity. Community tips stress buying from reputable sellers—avoid listings that seem too cheap for the capacity, as fakes are prevalent.
FAQ
Q: Is the Kingston DataTraveler SE9 actually waterproof?
A: Multiple users have accidentally washed or dropped it in water without failure, but Kingston doesn’t officially rate it as waterproof. It seems to handle brief submersion well, but long exposure isn’t advised.
Q: Why is my write speed much lower than 100 MB/s?
A: Real-world speeds depend on capacity, host port, and file type. Smaller files or older ports reduce throughput; some buyers also receive lower-spec variants by mistake.
Q: Can I use it as a boot drive for OS installs?
A: Yes. IT pros and hobbyists often use it for Windows or Linux installation media, with many confirming it works well for boot tasks.
Q: Does the SE9 get hot during use?
A: Some warmth is normal during sustained transfers. Reports range from “just slightly warm” to “noticeable heat” when plugged into devices long-term.
Q: Is it easy to attach to a keychain?
A: Yes. Its large loop fits key rings and lanyards, making it a popular everyday carry item for students, techs, and travelers.
Final Verdict: Buy if you need a stylish, metal‑cased, ultra‑portable drive that can survive years of physical wear—ideal for everyday carry and light to moderate file transfers. Avoid if you require consistently high write speeds for large video projects or can’t risk vendor quality issues. Pro tip: Source from trusted sellers to dodge counterfeit or wrong‑gen models, and pair with a faster SSD‑based drive for heavy workloads.
