File transfer Speed throttles

Hi everyone,

 

I am a new unraid user (still on trial) and I am testing my current system before buying the full software. This is my setup/issue:

Motherboard: ASRock C226M WS

RAM: 32GB ECC Crucial

CPU: Xeon E3-1246 v3

Case: Norco RPC-4224

HBA: Dell Perc H310 Flashed to IT mode

Drives: 

10x 8TB WD Red drives (2 parity 8 data)

1x 5TB Seagate (temporary cache drive to test)

1x 5TB Seagate (unassigned connected via USB 3.0)

 

I setup the array and precleared all drives (except the unassigned one that is hosting a data backup)

 

I start a 20GB .mkv transfer from the USB drive to the array and the transfer happens at ~145 MB/s for about 7-10 GB of the transfer then slows to ~60 MB/s for the remainin 10-13 GB of the transfer.

I tried this with and without the cache drive, and the same thing happens. Why does the transfer speed drop randomly?

That's the normal speed when transferring to the protected array, it should be faster when using the cache disk, are you sure it's using it when enable?

 

Other option would be to use turbo write:

I think I found my issue. I had setup the share incorrectly... was still set not to use cache drive...My mistake (sorry I am new)
