Manufacturer description
The Samsung BAR Plus 128GB brings USB 3.1 read speeds of up to 300MB/s to a drive small enough to live on your keyring, so moving a 3GB 4K UHD video to your PC takes roughly 10 seconds instead of minutes. The appeal here is that the BAR Plus survives the abuse a pocket-carried drive actually takes. The one-piece metal body is waterproof, shock-proof, temperature-proof, magnet-proof, and X-ray-proof, and Samsung backs it with a 5-year limited warranty. The integrated keyring loop is the practical detail most drives skip: clip it to your keys or a lanyard and it stops disappearing into bags…
SpecPicks Verdict
SpecPicks scored SAMSUNG BAR Plus 3.1 USB Flash Drive using a rating × review-volume × price-fit model applied to published specs and reviews across the PC & gaming hardware category. Samsung's PC & gaming hardware lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for PC & gaming hardware of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
How fast is the Samsung BAR Plus 128GB?
Samsung rates it at read speeds up to 300MB/s using the USB 3.1 standard. As an example, the company says a 3GB 4K UHD video file transfers from the drive to a PC in about 10 seconds. Write speeds are not published.
Is the Samsung BAR Plus waterproof?
Yes. The metal body is rated waterproof, shock-proof, temperature-proof, magnet-proof, and X-ray-proof, so it survives a trip through airport screening or an accidental run through the wash better than a plastic drive.
What warranty comes with the BAR Plus?
Samsung includes a 5-year limited warranty. Terms and registration requirements can change by region, so check the current product listing and Samsung's warranty page before you buy.
Does it work with USB-C ports?
The BAR Plus 3.1 uses a standard USB-A connector, so a USB-C-only laptop or tablet needs a USB-C adapter or hub. It is backward compatible with older USB-A ports at their slower speeds.
What can I fit on 128GB?
128GB holds roughly forty 3GB 4K video files, or tens of thousands of photos and music tracks, which makes it a practical size for backing up a photo library or carrying a video project between machines.
