Kingston DataTraveler SE9 Review: Durable but Slow Performer
“Four years on my keychain and still going strong.” That quote from a verified buyer on Amazon captures the enduring appeal of the Kingston DataTraveler SE9 USB Flash Drive, a device admired more for its toughness than its transfer speed. Across thousands of reviews and posts, users give it an impressive average score of 9.0/10, praising its metal body and reliability while admitting the performance can feel dated in the older USB 2.0 models.
Quick Verdict
| Verdict | Conditional Buy |
|---|---|
| Strengths | Durable all-metal shell, compact design, keychain-friendly size, reliable over years |
| Weaknesses | Slow write speeds (especially on SE9H 2.0 model), can heat under load, easy to misplace |
| Best For | IT professionals, students, travelers, and anyone needing a portable boot or backup drive |
| Avoid If | High-speed large file transfers are essential (video editors, frequent data movers) |
| Typical Price | $9.99–$62.95 depending on capacity and generation |
| Average User Rating | 4.6–5.0 stars (varies by version) |
Claims vs. Reality
Kingston’s marketing highlights three selling points: “premium metal casing,” “high-speed performance,” and “legendary reliability.” The real-world performance, however, varies dramatically between generations.
While the DataTraveler SE9 G3 promises USB 3.2 speeds up to 220 MB/s read and 100 MB/s write, users consistently report lower results. On Yandex Market, one buyer noted: “sometimes arrives with write speed 30 MB/s instead of 60 MB/s,” while another said their 64 GB unit “ran at 15 MB/s write.” These results suggest the performance gap between advertised and actual speeds can be wide, particularly in entry-level models.
The durability claim, though, is universally confirmed. Redditors have called it “sturdy as crap” and “never had one of these die on me.” A verified Trustpilot buyer celebrated that it “still functions after being dropped in water.” The drive’s minimalist unibody metal design, originally introduced in the SE9‑H USB 2.0 version, remains central to its appeal—small enough for a keychain, solid enough for everyday abuse.
A verified buyer on Amazon summarized the trade-off neatly: “While the speed on this device is not top notch, its performance is reliable and it comes in a great little package.”
Cross‑Platform Consensus
Universally Praised: Durability and Design
From Reddit to Trustpilot, users rave about its metal build and longevity. One Reddit systems admin said: “I keep one of these on my keychain… it’s handy to have essential drivers and tools without re‑downloading them.” The same sentiment appears on Twitter, where users frequently call it a “rugged little flash drive.”
The compact keychain‑loop design receives near‑universal approval. On Twitter, one review exclaimed, “it’s tiny and fits on a keychain so you’ll never forget it,” while a reviewer on B&H Photo wrote, “about the width of two keys and half the length… mine’s been banging around on my keys with zero issues.” Users in creative and mobile professions—like designers and IT support staff—appreciate its no‑cap, scratch‑resistant body. A Trustpilot reviewer called it “perfect for everyday carry; the first one that held up on my keychain.”
Common Complaints: Speed and Heat
Performance, especially for the older USB 2.0 SE9H model, is the main sticking point. A verified buyer bluntly described it as “way too slow… plug it in, get a coffee, and by the time you’re finished it may finally respond.” On Twitter, some users measured 1–3 MB/s write and 9–12 MB/s read speeds, far below modern standards. Yandex reviewers of the SE9 G3 variant acknowledged better performance—“1 GB transferred in about a minute”—but still short of the official 100 MB/s write spec.
Heat buildup is another noted weakness. One Yandex user remarked their 32 GB version “gets a bit warm even in standby in the TV port,” while others simply noted “growing hot during large file transfer.” Despite the heat, failures remain rare—thanks to that aluminum casing dissipating warmth effectively.
Divisive Features: Size and No Cap
The minimalist frame divides users. While many love the convenience, others warn “too small, easy to lose” (Amazon review). The absence of a protective cap leaves the port exposed; whether that’s minimalism or oversight depends on usage. An IT Redditor said, “no lid means fewer parts to lose,” while another Yandex user countered: “possible dust incoming—a plus and minus.”
Trust & Reliability
Long-term feedback is overwhelmingly positive. Reddit threads and Trustpilot reviews mention drives still running after three to five years of constant use. One Amazon reviewer wrote, “I have had one of these on my keychain for 4 years, and it still works great.” Others confirmed it survives accidental washes and even being run over by cars—an Amazon user stated the casing “in such material, even a car passing over won’t hurt it.”
However, counterfeit units and mislabeled versions have surfaced mainly on lesser online markets. A Yandex customer reported, “ordered the G3 3.0, received an older 2.0 version.” Another found a fake “1 TB” variant marked as SE9 G3 on arrival. Thankfully, Kingston’s warranty—five years plus technical support—helps reassure buyers who purchase from official or high-rated sellers. For reliability, reviewers recommend checking vendor feedback and avoiding listings that sound “too good to be true.”
Alternatives
When comparing alternatives, users most often cite SanDisk Cruzer, Kingston Kyson, and Kingston G3 variants themselves. The Kyson series earns praise for faster write speeds (“Windows installs in 15 seconds,” wrote one Yandex user), while the Cruzer Blade appeals for affordability but lacks metal durability.
For those who prioritize speed over toughness, the Kingston DataTraveler Kyson or the G3 Gold Edition offer a balance—advertised 200 MB/s read and confirmed 50–60 MB/s write by real buyers. Yet many still choose the SE9 for its form factor. As one Trustpilot user said: “They are built well, cheap enough to buy many at once if lost by kids.”
Summary comparison based on user consensus:
| Model | USB Type | Typical Read/Write (Real‑World) | Strengths | Weaknesses |
|---|---|---|---|---|
| DataTraveler SE9 H | 2.0 | 16 MB/s read · 6–10 MB/s write | Durable, reliable | Very slow |
| DataTraveler SE9 G3 | 3.2 Gen 1 | 100–200 MB/s read · 30–60 MB/s write | Faster transfers, same metal body | Can heat up |
| DataTraveler Kyson | 3.2 Gen 2 | 200 MB/s read · 60 MB/s write | Speed and metal quality | Slightly pricier |
Price & Value
Prices fluctuate across sellers: $9.99 for 32 GB USB 2.0 packs up to $62.95 for three units on Amazon; newer G3 versions range from $13.43 for 128 GB to $45 for 512 GB on eBay. Given these figures, the SE9 line sits in the low-cost durable category. Reddit users often buy multiples: “I have three servers running this flash drive.” For professionals handling moderate data, the combination of price and endurance makes it a smart utility purchase.
Resale interest stays strong—older SE9H units still sell frequently on eBay thanks to their reliability. Collectively, buyers recommend purchasing mid-capacity (64–128 GB) models, balancing capacity, performance, and cost.

Final Verdict
Buy the Kingston DataTraveler SE9 if you value durability and minimalism above raw speed. It’s ideal for everyday portability, boot setups, or school use—people who need a tiny, trustworthy capsule for documents and installers. Avoid it if your workflow requires frequent large file transfers or high-speed video backups.
As one Amazon user put it: “Small, sturdy, and full of bits. The perfect combination of all I’ve ever desired in a flash drive.” The community agrees—it’s a simple design done right.
