Just want to say thanks for all the helpful post i've read on here to help me setup my Unraid. There was at least 10-20 post, but the main ones are:

 

Helpful Post #1 - Thanks elkay14 

 

Helpful Post #2 - setup unraid without parity and "most free" space to help speed up transfer of all files to new server, then add parity drives and rebuild.  Was able to copy files from 5 8TB USB drives at the same time at 100 to 120MBs each stream for total 500 to 600MBs most of the time.  Can't find the post again, but thanks!!!!

 

I have it setup and it seems stable for the last 25 days so I purchased the PRo version last night.  I'm using an older computer to test run Unraid I had lying around. I don't run VM or any Dockers/Apps and never will. During Parity rebuild, CPU was running at 55% at most and ram was at 54%  (4GB total).   My question is, if I get a faster CPU and more ram, will it help in anyway in performance of Parity calculations during writes to Server. 

When mover is running, I get 50MBs on Parity & 50MBs on Parity2 & 50MBs on Disk(x), for a total of 150MBs. (using reconstruct write).

 

My Setup:

Intel Pentium G3258

 

4GB DDR3 1600 Ram

MSI B85 Gaming motherboard

1 x Rocketraid 644L esata card

1 x Rocketraid 622 esata card 

3 x Sans Digital 8 Bay Enclosures

22 x 4TB Seagate (2 Parity, 20 Data) (BTRFS)

2 x 512 SSD  (Raid 0 Pool) unsafe I know

10GBe SFP+ network 

 

 

 

 

 

I think that your CPU and amount of RAM (unless you are running a lot of other plugins and Dockers) would not be the limiting factor in writing to the array. What is your parity check time?  That is a nit more of an indicator of problems than file transfer speeds.   If there is an issue (Someone will probably jump in here also), I would suspect those Rocketraid esata cards are the most likely culprits.

I assume these are esata enclosures, if so they'll use a portmultiplier and will be a considerable bottleneck in any operations that reads all disks simultaneously, like parity check, rebuilds and writes with reconstruct write enable..

So do you guys think it’s  Esata or Rocketraid or both is my issues?

if rocketraid only then I’ll search for different cards. 

If esata then I’m stuck with what I have cause it would cost me too much to change all my enclosures. 

When I was running rocketraid in raid 50. I was getting 400MBs transfer rates in windows using Highpoint software.

Anyways any help is greatly appreciated

 Yes they are esata

Screenshot of parity started. 

Would this be a better card

The esata external enclosures are the bottleneck, no point in getting new controllers.
