Manufacturer description
The Samsung BAR Plus 64GB puts USB 3.1 speed in a metal shell small enough to live on a keyring. Samsung rates it for read speeds up to 300MB/s, which turns a folder of RAW photos or a 4K project file into a transfer you wait seconds for instead of minutes. The full-metal body is the point here: it is built to survive the pocket, the laundry cycle, and the airport, with Samsung's five-proof rating covering water, shock, magnets, temperature, and x-ray exposure. The integrated key ring loop means it stays attached to something you already carry rather than disappearing into a bag. Inside…
SpecPicks Verdict
SpecPicks scored SAMSUNG BAR Plus 64GB 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. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
How fast is the Samsung BAR Plus 64GB?
Samsung rates it at read speeds up to 300MB/s over USB 3.1. Note that Samsung's own product description cites up to 200MB/s read, so real-world speed will depend on your port, cable, and file sizes.
Will it work in an older USB 2.0 or USB 3.0 port?
Yes. The drive is USB 3.1 with backwards compatibility for USB 3.0 and USB 2.0, though transfer speeds drop to whatever the older port supports.
Is the Samsung BAR Plus waterproof?
Samsung lists it as water proof, shock proof, magnet proof, temperature proof, and x-ray proof. Check the product listing for the specific ratings and conditions Samsung tests against.
How much can 64GB actually hold?
Capacity is 64GB before formatting overhead. That is comfortable for photo libraries, music, documents, and installers, but 4K video projects will consume it quickly.
Is it reliable enough for important files?
It uses Samsung V-NAND flash. As with any flash drive, keep a second copy of anything irreplaceable rather than relying on one device.
