    Help! NUC5PPYH slow files transfer to external HDD...


      Hi all,


      I'm experiencing speed drops (even full stops for few seconds) while transferring files from the NUC5PPYH to a 5Tb Seagate Desktop Expansion drive.

      I've run few tests transferring the following:

      • Large files 2~25GB
      • Small files <1GB
      • Mix of small and large files

      All resulted with the same speed drops and stops.


      I've tried changing the "Removal Policy" and enabling/disabling "Write-caching" with no luck.

      Actually, "quick removal" policy had the least transferring stops and drops.


      The weird  thing is that I don't experience those drops using the same HDD plugged to my laptop, where It transfers at full rate!.

      So I assume that it's the NUC's fault.


      Hardware tested:

      • NUC5PPYH
        • Kingston Technology 4GB 1600MHz DDR3L PC3-12800 1.35V Non-ECC CL11 SODIMM Intel Laptop Memory KVR16LS11/4
        • Samsung 850 EVO 250GB 2.5-Inch SATA III Internal SSD (MZ-75E250B/AM)
      • Seagate Expansion 5TB Desktop External Hard Drive USB 3.0 (STEB5000100)
      • ASUS N550JV (Laptop)
        • Samsung 850 EVO 250GB 2.5-Inch SATA III Internal SSD (MZ-75E250B/AM)


      Operation System:

      • NUC5PPYH running Windows 8.1 Pro
      • ASUS N550JV running Windows 8.1


      Drivers are all up to date.
