I am having an issues with the pools. I setup a APP-Storage Pool to be used for Dockers and VM's. This pool comprises of 3 x Samsung 970 Evo NVME Drives. I want this pool to be a raid 5 or raid 0 not sure yet. But that is not the issue. The issue is when I go to the App-Storage pool drive and then go to balance BTRFS and set it to convert Raid 0 it doesn't change. Is there a way to do it via terminal / ssh or via config? Also Erase Button Doesnt work in the Pool...? Not sure. THank you

Original Post I tried to do as described here and it did not work. As well I was unaware that I was not boosting and I confirmed by checking cpu info in terminal. Not sure I added to the Terminal Modprobe powernow_k8 and it failed to load. I know I am probably doing something wrong. My CPU is a Ryzen 9 3900x Thank you.

It is over the network but I am running 10GB Lan SFP+ the write speed of the Cache is understandable being that I am transferring from a USB2.0 device but the Cache to Array speed is what doesnt make sense.

I call it real world speed test lol. I am transferring data from the Cache Drive to the Array that is where I noticed the speed difference. The file sizes are all the same roughly 1.5 to 5 GB

So short of that it is what it is. Unless some how I can find an 8TB SSD for a parity lol.

I am wondering the 8tb Reds are 5400 RPM's Would I see a gain if I switched my Parity drive to an 8TB Barracuda 7200 RPM? Or even a 8tb 7200RPM SAS?

We would guess it should be better though lol if not I guess ebay 8tb SSD slightly used lol

What about like a compute drive as my parity drive or a WD Black something with some more Balls??? Instead of a WD Red NAS. Maybe even like a 10k or 15k sas drive?

Any other options being that 8tb of SSD's wont be fun... any thing else any one can think up

humm so Raid 0 two 8tb Red's ?? Should give me better performance on my Parity Maybe?

So to the same point if I had 2 parity drives it would be even slower. I wonder if I just try to backup data to another unraid platform and use the slow parity there Then switch this machine to no backup???

Or just Raid 0 two 4tb drives or 4 x tb drives??? Rust Platters?? But doesnt Unraid Dislike that lol

Yea fill up is counter intuitive I know unraid does a parity but the backup to the parity is having the option to only loose 1 drive worth of data that is on the array

FYI Turbo Write increased my performance by about 40% which is great. I wonder if there is a way to optimize it more?

I will give turbo write a try I have not implemented it. My thought process was that if I use Most Free Allocation method I hoped that Unraid would multi thread the writes to the drives which would allow for all of the drives to be use simultaneously. This would mimic the function of striping but not striping by bit but by file.
