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.
