Try updating the BIOS. That generation is known for having wonky SD card slots that don't always work or are recognized in any OS. I have that same model and had issues until I updated the BIOS.
Unfortunately I do have the latest BIOS update installed (0054). Are you saying you are running Linux and the SD slot has worked out of the box for you? Do you mind telling me what distro you are using?
I'm not running Linux on it. It's using Windows. I was just saying that many people have had problems with the card reader not working in Windows and Linux. If you install a Linux distro that has been released/updated in the past few months, it should work. Also, check the BIOS settings for the SD card reader to make sure it's enabled, with read/write.
In regard to your concern, at the following link, you will be able to see the list of supported OS for your Intel® NUC Kit NUC6i5SYH:
Supported Operating Systems for Intel® NUC Products
There you can confirm that our customers have reported as tested the following versions ofLinux: Fedora, Gentoo, Linux Mint, Lubuntu, and Xubuntu.
You can test those versions if it is possible, and as you have an open question on Ubuntu Communities, you can also ask if they have tested the ones that I have provided.
I am looking forward to hearing from you.
My system is: Ubuntu 14.04.5:

SD card works perfect (tested with Transcend and Samsung SD and SDHC microSD with SD card adapter) under Ubuntu 14.04.5/64bits
New versions of Ubuntu (like other OS's get buggy in the beginning and are fix by new releases. I believe that 16.04.x will address most of the bugs.
I can say that Intel wifi 8260 is still buggy (tested also with Lenovo laptop with Windows 8.1) but works for 802.11bgn (for 802.11a not stable, looks like a sync bug)
Intel should keep a opened mind and work with Linux community because we support desktop development (which I believe is Intel's main business model) and we buy not only for personal use but also for businesses, and also we can help support platforms by open source development for Intel hardware.

I was reviewing this thread and I was wondering if you were able to resolve the issue with the SD card slot.
If not, please check the following information:
In addition to this, please bear in mind that the supported SD cards sizes are from 8GB to 128GB.
Please let me know how it goes.
I just tested all the SD and microSD cards that I have here with Ubuntu 14.04.5 Kernel: 4.4.0-59-generic x86_64 (64 bit)
on the NUC6i5SYB version: H81131-504
with firmware SYSKLi35.86A.0054.2016.0930.1102 date: 09/30/2016
Many are formated FAT, FAT32, NTFS, EXT4 and combination of partitions with them
This is the result table:
Sandisk 1GBytes microSD with SD adaptor ok Sandisk 2GBytes microSD with SD adaptor ok Nokia 2GBytes microSD with SD adpator ok AData 2GBytes SDcard x50 ok KingStone 2GBytes SDcard (SD-MO2G) ok KingStone 4GBytes microSDHC (SDC4) ok Transcend 4GBytes SDHCcard (SDC6) ok* Patriot 8GBytes microSDHC (SDC4) ok SiliconPower 8GBytes SDHCcard (SDC6) ok KingStone 16GBytes microSDHC (SDC10) ok Sandisk 16GBytes microSDHC ultra (HC I) ok* Samsung 32GBytes microSDHC-EVO (HC I) ok PNY 128GBytes microSDXC-Elite (HC I) ok**
* Two partitions (FAT and Ext4)
** EFI system (FAT32/EXT4/SWAP)
The only strange thing that happened in the beginning of the tests with de 1GByte microSD was that I used the original old adapter that came with it and it was not recognized. Then I used a new Samsung adapter with the same microSD card and it worked. After that I used the old SD adapter again and it worked too. Very strange.
Apologies for going dark. I was finally able to get to the bottom of the issues I was having. I believe there is a physical defect with the microSD card or adapter. As the naked microSD card works (sometimes) in it current role, and it only works sometimes when I plug it into other windows machines. My regular sd card was formatted with exFat and I had not installed the necessary drivers to read it when I was testing the slot.
