very good stick and indeed if you want it for 4K movies and because these sticks get hot, they dissipate the heat because they are metallic!!

Recognizable and fast. The USB port slot dimensions are 12.0 X 4.5 mm, according to standardization. This particular one has dimensions of 12.5 X 5.0 mm, resulting in difficulty in fitting it.

I have owned it for about a year, I use it exclusively in the car. I keep adding music to it, it's almost full, I need to get another stick, but I won't get the same one because it has one flaw that annoys me every time. It doesn't have consistent performance when you add music to it, sometimes it's fast and other times it slows down completely and drags, just like that and it always does it, then suddenly it's fast again, no matter which port I plug it into on the computer (there are six, two of them fast). Nothing else has happened to it so far, except for this.

Having had the 128GB (still alive and kicking) for 3 years, I decided to go for the largest in the series to gain double the speed in write. No matter how much data I tried to write all this time, the speed (especially with large files) remained steady at 110MB/sec. It's not discouraged by anything!
Another great asset is its durability. And when I say durability, it withstood a wash in the washing machine at 1400 rpm and a fall from the third floor (that's when I discovered it) when I was hanging clothes. It still works, as if nothing happened!

I have it only for a few days but it does what it promises, it's great. If anything changes later, which I don't think will happen (Samsung = Guarantee), I will come back.

Very fast file transfer, stylish, small in size but with SAMSUNG performance and quality. I highly recommend it. Excellent purchase at an excellent price. I bought it for use on a PC.

Very good for this price, Waterproof and durable, also one of the most elegant USBs I have seen.

Very good for its price.
I have had it for 1 year and so far it has not presented any problems to me

It is good. Relatively fast. The paint of the metal casing easily wears off at the computer port area.

Beautiful construction but disappointing performance.
Non-linear recording with values ranging from 40 to 65mb/s. For 3 seconds it records at 95mb/s and immediately drops to an average of 50mb/s.
At this capacity, one can achieve much higher performance with comparable reliability.
This is probably why the company does not mention the recording speed anywhere, only the reading speed.
In this price range, one can find recording speeds ranging from 200 to 400mb/s.
It's a shame because I like the company's products.

4/2020: The color has faded heavily in many areas beyond the slot, and the speed has disappointed me in many short-length files. A 5-year-old USB stick from another company is much faster

I had doubts about the speed mentioned by another user for the 32GB version, but in the end, my trust in the manufacturing company prevailed.

The speed test I performed with gnome-disk-utility 3.30.2 as soon as I got it, gave the following results:
Average read rate: 211.0 MB/sec
Average write rate: 48.1 MB/sec
Average access time: 0.17 msec

I definitely recommend it as significantly better than similar devices.
