Can someone try to copy a file few GB big using File Explorer, from external USB 3.0 drive to internal storage (desktop). What is your speed? Which BIOS version do you have?
Please I need this information ASAP to determine if there's something wrong with my NUC! I can still return it to the store...

Thank you for contacting Intel® NUCs communities.
I understand that you want to check the expected speed for USB 3.0 let me help you.
40 MB/s is the speed for USB 2.0, please make sure you are using the USB 3.0 located in the front of the NUC.
Let us know your system configuration as follows:
We recommend you to install the latest BIOS version available here
You can check how to do the BIOS update here.
Also try to complete a Windows Update.
I've tried with different fast (verified and working) SSDs, USB 3.0 thumb drives and portable disks, on all four USB ports.
I flashed the lastest v42 BIOS, Win10 Pro x64 was fully updated, all drivers from Intel support page installed, the works.
In my opinion, if this is not latest BIOS's bug, my NUC is defective.
Well, very interesting...
I was running on BIOS 41 when I ran the original tests. After upgrading to BIOS 42, my results varied considerably:
From Seagate Backup+ 4TB to the eMMC, I peaked at 40 MB/s and averaged 38 MB/s.
From (older) Western Digital MyPassport 2TB to eMMC, I peaked at 42 MB/s and averaged 40 MB/s.
Almost a 50% drop in USB performance. There is definitely something wrong in BIOS 42...
Is this on the NUC6CAYH or the NUC6CAYS? The CAYS has 32GB of eMMC on-board which is slow storage, the CAYH has no on-board storage so it should be quite a bit faster if you are using an 2.5" SSD. I tried it on a CAYH with an older 2.5" SSD and was getting around 75MB a second when transferring a 5GB folder of files. This was on BIOS 0041. On BIOS 0042, I saw the same file copy drop to 35MB a second. Looks like there is an issue in this latest BIOS.
Hi there. After the latest BIOS update i did i have the same USB 3.0 port issues as you do. Read my post if you like. Hope they figure this out ...
It's definitely a thing with this BIOS. I've also noticed random flickering on two AOC 27'' FullHD over HDMI. But then there was no flickering on Acer 2k and Samsung FullHD TV, both over HDMI.
May I suggest you to open a support ticket? They are killing me with questions about USB speed issue almost suggesting there's something wrong with MY system setup and testing capabilities when there's obviously a NUC-BIOS issue...
Intel is aware of the USB issue and has reproduced it in their lab. Their BIOS folks will be looking into it. A fix should be in the next BIOS release.
A user reported that they found that Windows had set the refresh rate to a wonky value. After setting this properly, they stopped seeing the flashing blank screens. I suggest you also look to see if this is set correctly for your monitor - and let us know, regardless.
Hope this helps,
P.S. Please do not describe this as flickering. Flickering is a totally different phenomenon that occurs constantly. This is a (seemingly randomly-timed) flashing blank screen.
sorry for my english, is a translator.
bios 0040 110 Mg / s HDD Toshiba 1 Tera. Blue disk light USB 3.0.
bios 0042 30 Mg / s HDD Toshiba 1 Tera. White disk light USB 2.0.
The same hard copy, before and after the update of the bios.
Impossible to lower the bios revision 42.
Due to a security enhancement, it will not be possible to go to any BIOS earlier than BIOS 0042.
They have broken intel nuc with bios 0042.
I want a solution or a change of equipment, this is incredible.
