Many Thanks Frank

Thanks Frank. Other than set as "No", can I remove it from the "shares" list?

I using "Disk Share" to share root of one of my harddisk. (Settings as "Private") When I create folders under that share, it will auto. make the new folder as "Public" share under "User Share"... Is it a normal behavior? And how can I remove those "public share" from list?

Thanks a lot, Jorge 👍 I rebuild my RAID5 with original plan (now with disk share), I can now have 4xx - 5xx write-in speed~~~ 😃 Never imagine the coding in "User share" will cause much performance issue: https://blog.insanegenius.com/2020/04/25/unraid-user-share-vs-disk-share-smb-performance/

OMG 😶When I activated disk share, the speed write-in changed to around 8X - 100MB/s How come @@"

Many Thanks 😃 My information as follow:

Thanks Jorge, I also hear about iperf from other post, however I don't know how to use it. I downloaded the program to my Win10 PC, seems I need to type some command things. Another silly question it, in some post, I find that iperf is runnning in Unraid. What should I do in my case? Run from Win10 client PC or Unraid or both 😅?

WD Black SN750 NVMe I tried, no wonder what type of harddisk, array, pool setting, the writing speed keep around 100 MB/s in frist 15-20 second and then drop down to 4XMB /s I uploaded a copy of log file to google drive as follow: https://drive.google.com/file/d/1y6975SxT02Bg6fzwXbsqE9bspCAKPJEB/view?usp=sharing

Feel really strange, I build a single disk pool with one of my SSD, again write speed drop down to 4x MB/s but read speed can keep at 600 MB/s. How can I check what's going on? My build is: ============ Intel® Core™ i5-9500T CPU @ 2.20GHz ASRock B365 Phantom Gaming 4 American Megatrends Inc., Version P4.30 BIOS dated: Thu 14 May 2020 12:00:00 AM PDT 32 GB DDR4 Memory LSI SAS 9207-8i SAS/SATA 6Gb PCI-E 3.0 SAS HBA WD HC520 12 TB Harddisk x 8 Intel X520-DA2 10Gbs LAN Card sydisk-diagnostics-20210423-2136.zip

Thanks and I attached my log file to the original posts

Hello, I am using UnRaid 6.9.2 right now. I found that my write in speed in Unraid is pretty poor, usually it start around 100 MB/s and then drop to 4X MB/s even writing in a SSD. However, the reading speed keep stable @ 500-600 MB/s How can I check the bottle neck write-in slow? Thanks. sydisk-diagnostics-20210423-2136.zip

I tried to select "only" under "Use cache pool (for new files/directories)" in "Shares" and now able to access the share folder via SMB. How ever the performance is really terrible @o@" Starting: 110 MB/s then drop down to 30-45 MB /s Is that normal? I am using 10 Gb LAN right now

Thanks Jorge, my parity check is done. However, I found that only "Array Disk" can be add to "Shares". The "Pool" disk seems cannot be show up in "Shares". Did I missed something?

Thanks for your advice 😀 I am now adding a 4 x 12TB RAID pool 1st, the others will remain as normal array. Anything I need to pay attention on using btrfs RAID5?

Thanks Jorge. Do you mean that such "RAID5" is not that safe 😅? Some forum also say that Btrfs "bugs" cause RAID5/6 not stable
