I am not Intel but am concerned. I too ordered the 2.5" SATA model as my second D54250, however mine supposedly won't ship for two weeks. There is a post from someone else today about a different "H" model who seemed to have similar problems and was attempting to use a different cable and power supply to diagnose. So unfortunately your situation may not be unique, and Intel's reply was that they only test mSATA, not SATA. I wonder if anyone has working 2.5" (H) and/or whether we should stop ordering those new models until there is more info.
I apologize for this issue.
The links below provide a list of tested and customer-reported peripherals.
Whats your thoughts on whether 2.5" SATA SSD drive compatibility will be improved?
I figured that it was probably a lost cause so I went ahead and bought a Crucial 240GB mSata drive this morning. They are pretty reasonably priced from Crucial at the moment.
It's a great pity. I wasn't expecting SSD drive compatibility issues.
same here with my D54250WYKH.
I have tested:
-OCZ Octane 256GB (OCT1-25SAT3-256G)
-PNY 240GB (SSA2S240GC2DE16-TA)
-crucial m4 SSD 2.5 128GB (CT128M4SSD2)
-Intel 530 Series 240GB (SSDSC2BW240A401)
The last one I have bought because the compatibility advice: Intel® NUC Boards and Kits — Tested peripherals
Unfortunately also not working!
2,5'' HDD was recognized by BIOS without any problems.
Help is greatly appreciated
More models may be added in the future, especially if customers report them to work with Intel® NUCs but we do not get to test all models available in the market.
I have connected the PNY 240GB SSD direct to the connector on the board with a working SATA data and power cable. This test was successful and therefore I have returned my NUC to the dealer. The new one I have got back is working without any problems with the Intel 530 Series 240GB SSD.
Conclusion: My old NUC has had an damaged SATA-Port and/or cable and/or connector.
