SAMSUNG BAR Plus 3.1 USB Flash Drive, 128GB, 400MB/s, Rugged Metal Casing, Storage Expansion for Photos, Videos, Music, Files, MUF-128BE4/AM, Titan Grey

This is a great choice for a speedy USB drive, looks slick and reliable. I’ve bought a silver 64GB back in 2019, still works great. Recently bought a Gray 256GB variant, I use it for easy video transfers between devices, and also project files. The Speeds during benchmarking are as expected, ~400MB/s Read speeds and ~100MB/s write speeds, real world performance will vary but performance is high nonetheless. High-value USB drives!

I've purchased the Samsung Bar Plus 3.1 USB Flash Drive 13 times between October 2018 and October 2024, including various capacities such as 32GB, 64GB, 128GB, and 256GB. The quality, reliability, and blazing fast performance of these flash drives have been consistently impressive. After four years of heavy use in countless machines, one of the 256GB flash drives stopped working on September 25, 2025. Fortunately, I had just made a backup copy, so I wasn't too worried. Samsung Support was amazing to work with; the representative provided a link to complete the RMA form and assured me that a UPS return label would arrive by email within 48 hours. I highly recommend these flash drives for their quality, durability, outstanding performance and excellent customer service. The attached screenshots from CrystalDiskMark 9.01 are test results of Default, Peak Performance, Real World Performance and Demo test profiles. I’ve also attached a picture of the Samsung flash drive along with the UGREEN USB to USB C Adapter and JSAUX USB C to USB Adapter. Both of these adapters are great!

Great USB for the money. Looks sleek and super cool

I bought this Samsung BAR Plus 128GB flash drive three months ago, and it has performed great. The metal build feels premium, file transfer speeds are fast, and I’ve had no issues with overheating or disconnecting. Still works smoothly after regular use. A reliable and solid USB drive for everyday storage needs.

Definitely a nice little high speed flash drive with sufficient storage. Only downside is it gets extremely hot during operation. When I say extremely hot, I mean it literally burns your finger to touch it for more than a second unless you let it cool down for a few mins first. Other than that, it works great and appears to be built with very durable material.

Works as it should and was great bang for the buck. Interesting shape and decent size. Seems to write plenty quick enough; and I've never noticed any heat, though I don't overly tax it. A good basic backup device.

Super fast and small. I am super happy with these drives. I purchased two 256gbs drives, and they are both exemplary. These work with Mac, Linux, and PC. They are easily and quickly read by these three different operating systems. I highly recommend these at this price point.

Samsung makes quality hardware and they got this design right. It is simple and sleek which not only looks classy but ensures it fits into any USB port without crowding out other USB devices next to it. Since they make everything from the flash memory inside to the outer shell Samsung has total control over quality. Reliability is the main reason to buy this drive. The flash memory will last for many write cycles and the drive itself is built to take abuse. I gave this to a family member who accidentally put it through their washing machine and dryer but because Samsung wisely made it a sealed unit the drive survived. We did a full reformat to check every cell and there wasn't a single error. The drive came out of an extended wash and dry cycle fully operational. This is the USB drive to get.

Fast shipping and perfect items , thanks
