Actually you didn't get my point. I own both samsung pro and lexar 2000x cards. The real world difference (not benchmark) is of the 4-5x magnitude. Hence there is something wrong with that benchmark.

I think it depends on type of benchmark - even if you test it on PC: Kingston Mobilelite G4 USB3 UHSII reader Sandisk 64GB UHS-I Extrem PRO 95M/s R/W  USBDeview - 42MBs / 92MBs

All SDXC cards where formated to ExFat standard, no freezing of crashing after Dev test. 

Cards also tested with H2testw to detect true read and write speed.

Something is wrong with this bench. The 2000x can do 5-6fps when buffer is full with raw+jpg.

Tommix, no way. That's why I say there is something wrong in the bench. Going from a samsung pro to a lexar 2000x is a huge jump on my camera. You go from about 1fps when buffer full to 5/6fps. And the clearing time is about 3-4x better.

The Memory dev test is probably not very reliable to be honest, my computer is from 2012 and when you can see they are 10MB/s faster than in Samsung Dev test and the SD card reader in the Samsung should be able to read the card at full speed so there is definitely something software faults with the NX1 regarding dev test.

What is important?
How quickly is the SD card in the USB-cardreader from Kingston on a USB3-port of a Gigabyte motherboard?
Or in a USB-cardreader from Lexar on a USB3-port of a Asus motherboard?
Or all on a Mac?

No, what we all have in common is the NX1!
What is crucial to know is, what are the fastest cards in the NX1.

And it's not interesting if there 68.123 KB/s comes out.

We don't know what size of blocks the NX1 writes at the test.

Is the write speed of an H.265-file higher or lower than it is with RAW- or JPEG- or RAW and JPEG? I don't know.

 

Sure is definitely that we have a common basis for comparison.

This here should only be an aid for the purchase of an SD card.

OK, but according this logic (at least) all first four cards should achieve same speeds in the dev benchmark - if camera would be the limit factor. Because they are definitely faster than shows this dev test. My Sandisk Extreme Pro 95MB/s can achieve almost 92 MB/s write speed with best card reader.

Going to Lexar 2000x still means benefit of another 15 MB/s (53MBs vs 68MBs in dev test). Why there is difference in speed if cards are much faster than camera can use?

What im sayin'- camera cant write faster so no point in faster than lets say 65MB cards. Apposite in camera test is what is matter, not the real speed. Who cares how fast card is if your camera cant use that speed? For example Canon 650D have bus speed only of 40MB/s - what im saying -sometimes and very ofter in camera hardware is limiting speed not only card.

I dont own so far nx500, but i believe that card have effect on burst mode.

 

The above applies here too :)

The first two steps are little messy... Can you explain me step by step? thank you!

It's easy.

- On your computer Create a text file named nx_dev.adj      -      Write inside the text file smart_camera 

- Copy the text file to your SD card (in the main SD folder) and put the card in your camera.

- Power on the camera.

- Set camera to Auto on the mode dial

-. Press these buttons in order:

Down

OK

up
 
OK
 
right

exposure compensation button but keep it pressed 
 
press OK (normally, don't hold it)
 
now leave the exposure compensation button that you were keeping pressed,

 

-You should now see the DEV menu.

-Under System Settings you will see Disable Mov limit, and Release without lens. Turn these two options ON

-Do not forget to delete the nx_dev.adj file from the SD card.
