## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Speeds!
*by S***T on January 5, 2021*

Wow! This is the first 3.1 USB flash drive that transfers at advertised speeds. Movie files take less than a minute (6gb). I’ve included a screenshot from flashbench with benchmark speeds and posted the log below. I like that the flash drive has both a 3.0 and 3.1 connector. No matter where I go, I can connect my flash drive. I want to also note that I am using the front panel of my PC when I ran the benchmark. Might see increased speeds when using the back of the computer connected directly into the MOBO.Just some words of advise. I you are having issues with transfer speeds, try plugging the drive into the back of the PC.Refreshing devices.Refreshing devices.

### ⭐⭐⭐⭐⭐ Awesome
*by T***A on March 20, 2025*

Awesome

### ⭐⭐⭐⭐⭐ Fast read & write speed, small, fits well in USB port, and it was on sale.
*by R***O on August 17, 2021*

Pros:I bought a SAMSUNG Duo Plus 256GB USB flash drive on sale for around $43.99 and that's a good price compared to its competition in July 2021.Its read & write speeds are fast, although similar to ALL flash drives that I have used, its speed varies a lot and its speed depends on the file size and formatting of the drive. Small files write much slower than large files, and that is typical of ALL flash drives (a.k.a., thumb drives) that I have used in the past 20+/- years.Cons:SAMSUNG Duo Plus' write speed varies a lot, but it writes faster than the Kavolen drive that I have, and this SAMSUNG drive writes much faster than the Elefull drive that I have.Comparisons:My Elefull drive was lower priced $ but it developed multiple ''bad sectors'' after using it for 1+ months.My Kavolen drive had more and more slowdown issues in reading & writing data after using it for a month.So far, after using this SAMSUNG drive for 1 month, I haven't noticed any read/write issues or bad sectors.
