This has been a great USB drive—solid construction and good performance. Transfer speeds are fast and it’s held up well after a year of regular use. Also a good value for the storage you get.
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!
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.
Reliable, physical capacity matches stated in specs.CONS: not as fast (stated 400mbs, benched at 200) write speed (reported 128mbs, benched about 60mbs)Overall good drive and good deal at $20. I've had all kinds/brands of drives over the years .. Sammy drives and cards have never failed .. not one. All other brands have.
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!
