This has been PERFECT! 9/30/2019 11:25:25 AM

Pros: Performance speed - USB C

Cons: Only 2 of 3 pieces are able to be looped for safe keeping.

Overall Review: This stick has been a beauty, and a perfect way to add music to my phone. The transfer speed is so much faster than usb, and both phone and computer detect it just fine. It's done what I wanted superbly. There are 3 pieces to keep track of, and only 2 allow themselves to be attached to any sort of loop for safe keeping.

Great little flash drive! 8/27/2019 8:27:04 AM

Pros: Versatility! Being able to use this with either a USB-C or a USB 3.1 is a huge plus!

Cons: Nothing! What’s not to like about a product that works the way it is supposed to, and was fairly priced? One wish is that they would have included a string to thread through the holes on the body and the cap to help you keep from losing the cap.

Overall Review: We bought two of these Samsung Duo flash drives. They are solid, compact, and perform flawlessly. We have been looking for a good USB C flash drive to use with our new MacBook Pro laptops. This little drive from major brand name Samsung not only fits the bill, but adds the additional versatility of being able to use it in a standard USB 3.1. This makes it the perfect tool for transferring files between different computers.

Convenient but SLOW 8/20/2019 2:49:33 PM

Pros: Convenient USB-C to regular USB adapter

Cons: Very slow! Using USB Flash Benchmark 1.0, I got write speed of 40 MB/s and read speed of 290 MB/s on large files and 30/270 MB/s on small files.

Overall Review: I like the convenience of having both regular USB and USB-C connectivity on a USB flash drive but do not expect write speeds above 40 MB/s. The device is stylish but relatively big. All in all, I think that price/quality/speed is good.

Stylish but super slow 8/10/2019 8:29:19 PM

Pros: stylish
convenient(ish)

Cons: SLOW
easy to lose cap and adapter

Overall Review: It is advertised as up to 200mb/s for the model MUF-32DB, but I am only getting a max of 30mb/s during any transfers. Like I get that it's not going to be the advertised speeds but only like only getting 15% come on. and the USB A adapter cuts down read speeds down from 200mb/s to 44mb/s with write speeds staying about the same at around 30mb/s

Cheap plastic lines the tip 4/29/2019 8:51:00 AM

Pros: It is still functional, but I don't trust putting it in my MacBook anymore.

Cons: The tip of this is lined with plastic which will break apart with normal use and get lodged in your usb-c port. I had to have apple tweeze the chunks out because cables weren't seating correctly.

Not as fast as a C drive should be 4/20/2019 2:14:18 PM

Pros: on my Acer laptop got speeds of 220 read and about 75 write speed using crystal disk mark. I got this to use for recovery drive for laptop which it serves well it has been partitioned by Acer to 32GB and 28GB instead of using the full 64GB so now i just format the extra partition for my DATA which is software music pictures and documents in case when on the road the drive fails gets infected and can't be removed or any other problems that I may need to put new onto drive, I also have a programmed drive that I update from time to time as windows come out with a cumulative update and keep my budget current too

Cons: not as fast as I had hoped but will do for my needs the specs say average of 200 so should not have expected anymore
