Are cheap USB sticks of worse quality?
Can a very cheap USB stick be worse than an expensive one?
What exactly would be the difference?
I bought a 128 GB USB stick from smart usb for 4 euros while on holiday in Türkiye.
What is the difference between this and one from SanDisk, for example?
Of course it can be worse.
And the difference is the speed.
But it doesn’t matter what the stick is designed for.
For example, this has a speed of 380 /420 costs 38 euro
