Hello there, i bought this flash drive (dual ultra 3.0 64GB) yesterday and i’m getting VERY SLOW writing speed.
At first, it starts writing like 50MB/s but after a few seconds the speed starts decreasing until it reaches 10MB/s. After that, it doesn’t get any faster, in fact, sometimes decreases until 6MB/s. It’s even slower than my 2.0 drives!
I’ve got a Lenovo Ideapad 310 with a i5 6200 2.3Ghz and 8GB RAM. Of course it’s plugged to a USB3.0 port and have all the drivers updated.
I’ve just tried it on a 2.0 port and stays at 11MB/s, just like in the 3.0. Tried another 3.0 flash drive (verbatim 128GB) on the same 2.0 port and got 25MB/s (wich es good for a 2.0 port)
I’ve formated the flash to NTFS so i could transfer big files, but i think it shouldn’t cause any lost of speed, at least not to the poor 11MB/s i got
Anyways, sorry for bad english, and thanks to everyone that replies
