Hi JorgeB. I've already received the new disk and now it is way better. It completed the parity sync in 18h and 30m at an average speed of 120mb/s. My parity drive has 8TB. Do you think that those values are good, or is there any improvement to do? Thank you.

Thank you JorgeB. I will try to return this disk and replace it by a Toshiba N300 also with 8TB (Serial No. HDWG480UZSVA). I think that this one is CMR. Once I receive the disk and test it, I will update the thread!

Hi everyone, I bought recently a new drive with 8TB to use as parity (until now, my unraid server had no parity) Well, I mounted it, and started the parity sync. The speed of parity sync is, in my opinion, really bad, around 35MB/Sec, which will take days to finish. I've read some posts and did some changes (disabled VM manager and docker, and assure that cache write was turned on). Now, when I start the parity sync, it goes fine (around 170MB/Sec) until aprox. 8%. At this moment, the speed drops to 35MB/Sec. I've identified that at the beginning, the disks are rarely written. When the speed drops, the disk 2 (sdd) is written almost every second. You can find attached the diagnostics, and a print screen of my array. Anyone can give me some hints on how to speed up things? weebuzserver-diagnostics-20230315-1122.zip

My CPU usage it's normally between 10 and 20%. Although sometimes it reaches 50 and 100%! My RAM is always pretty empty (around 20/25% full). I will try to buy a 128gb SSD and test if there are improvements in speed. I don't understand you last quote. You said that I can use the Disk Speed Docker to test my disk, although I din't understand what you mean with "which you would isolate using an SSD and seeing "no" improvement." If the problems are not in the disks, and I bought an SSD it will improve? Thank you.

Hi! I'm new around here so I don't know if this is the correct place to put my doubts. So, nowadays my config is like that: HDD: 1 x 6TB HDD, 1x 3TB HDD and 1x 1TB HDD No parity disk yet and no cache disk. CPU: Intel Celeron G3930 (dual core with no hyperthreading) RAM: 8gb GSkill DDR4 GPU: None The main use that I give to the server is as NAS Server with shared folders to store photos, movies and files that are connected to Kodi. I also use it as cloud (opened through the web for me and my family to use) using the Nextcloud and MySql Apps and for download files direct to the server using JDownloader and Deluge. I would like to improve the speed of the files upload and download either for the cloud and for the shared folders. In a near future I would also like to do some virtualization with it putting a Windows VM running for basic image editing and some games (they are not powerfull games). So, in order to improve the read and write speeds, I was thinking in add an SSD to the build as a Cache Drive. But, after some research I've identified that maybe I won't have any gain once that I don't have a Parity Drive. Is this true? What improvements and updates do you suggest? Thank you for all your help!
