This is very good fast speed, bags of people ignore instructions that come with the packaging and then moan the USB 3.1 transfer speed is slow.

When you received it, read the back cover of the packaging, bottom right, there is a very small picture notice to ask you to connect the two tiny arrows when using USB Type A 3.1, make sure the two arrows , one marked "USB 3.1" point to each other on the same side for maximum speed.

I found the C connection equally slow. i will check this out later.
I have the 32GB version of this. Dual connection is handy. Disappointingly slow write speeds across several devices i have. <30Mb/s in a Surface Pro, Laptop and desktop, all USB3 or C.
I have many older drives that outperform this by orders of magnitutde.

Hope this helps, when in doubt use evidence based methods, possibly on two or more computers ( I keep my comparisons of all my purchased memory in a MS Word document since n years):-

Using the USB 3.1 connection (not USB-c) to my USB 3 hub and then to my laptop running CrystalDISKMark, just now ( I have yet to do a USB-C transfer data measurement , my Samsungs transfer very fast though subjectively.) BTW: You said that yours is an Order(s) of magnitude means the 10 times, which I doubt very much on a balance of probability, but is possible.

Well there we are.
I have plugged the thing into a USB 3 port on a Lenovo 470, the same port that i achieve 150-200Mb/s write speeds with the same file on a PNY960GB portable SSD (apples and oranges i realise, but there to indicate no bus problems)

Regardless of which way around I connect the C section into the USB host section, i achieve circa 20Mb/s write speed from a 3GB MKV file stored on my C drive (an Intel SSD)
I can see the arrows you speak of, but whether lined up, or 180 out, write speeds are identically slow.
Perhaps i have a lemon?

*I have several, years old, Sandisk Extreme USB drives that achieve 150Mb/s+ writes all day long.

4k write is okay but only 50 MB/s write for sequential seems a bit rubbish. Still better than most el cheapo ones by a long way though i guess.

What are the sector sizes like though? I have found that on my San disk extreme pro while quick the size on disk is massively different. For example if I were to stick 10 GB of mixed size files on it would take up 30GB on the drive. This is how they get the fast transfers nowadays it seems. My old San disk extreme is far better and didn't do this.

So I wonder if other brands like Samsung also do the same thing.
I feel like if you want quick nowadays you need to get an m2 drive and stick it in a caddy

Speeds like a lemon, check out with another PC, with this evidence, return to Samsung!

You said, "50 MB/s write for sequential seems a bit rubbish." This is an invalid statement for general use.


Depends on where the bottleneck is, as 50MB/s constraint is along my data path. You may just google for pictures for others' results. Mememory is optimised for read or write, different files sizes in the controller circuit for different application.

SO this Samsung does a lot better writes : source ePhotozine for another Samsung memory stick ephotozine.com/art…107

I guess English is not your first language so I'm not sure exactly what you are trying to say.

I don't think this Samsung drive is terrible, it is reasonable compared to many others. But I would prefer to see a benchmark with a decent data size 500 MB even 5 times isn't enough to test properly.
