The external storage is actually mounted via Docker. But every folder created by Nextcloud via web UI or App gets wrong permissions.

When creating a new folder in a Local external storage directory, Nextcloud gives it the permissions drwxr-xr-x. Which isn't in accordance with the unRaid Permission scheme, and prevents me to change it via SMB afterwards. How can I tell unRaid to always create folders with drwxrWxrWx (777) permissions?

I have the same issue her on my MacBook Pro MacOS 10.14.6 UnRaid 6.7.2 SMB Download averaging at 37MB/s SMB Upload averaging at 117MB/s @limetech Are there any informations how to address this issue?

Let’s take 5 years as an example. From my calculation TBW will be at about 1000 maybe a bit less because of WA and the larger drive size. 970 will be way beyond the specified TBW. But still in warranty. SMART Test will again be failing because of percentage used over 100%. I‘ll again have no idea if the drive fails or not even if it still works. PM983 will be still in spec for TBW but out of warranty because of the time. Percentage used and SMART Test will be ok but no waranty. Usually I claim warranty when there is any but if the claim process is costly and the prospects of success are low. I just leave it. Wich is my experience for Samsung consumer drives. No idea if this will be different to Samsung Enterprice drives. Advance RMA maybe? WD offers that. What Formfactor goes: My MB accepts 22110. As you have both drives installed: Do you encountered any differences in read or write speads? How is each percentage used value scaling to your TBW values? Are they indead scaling different as I assumed above? Could you maybe post those values for each drive as a reference?

Trim was always running daily on my SSD. Can I improve anything about WL? Would you rather suggest buying a bigger consumer SSD than a better rated smaller enterprise SSD to just leave space free and to hope for the controller to make good use of it and thereby reducing the WA? About 180-200€ for a Samsung PM983 960GB M.2 seams reasonable for me. Would you consider that as enterprise grade or would rather buy a Samsung 970 Evo M.2 1TB for about the same price? Thank you very much for sharing your expertise on that.

Thanks for your detailed Explanations. Downloads and Plex Transcods cannot be the main reason for the nearly 400 TBW. That seems more reasonably to me. Or am I understanding anything wrong here? If not, overprovisioning seems as the most reasonable approach to me. Is it possible to over provision any SSD Myself? I don't have any VM vdisks and my Docker Image is about 100gig so 500gig of usable space is plenty enough for my use. Switching to 1 tb or let's say overprovisioned 840gigs would already be a huge upgrade for me but I don't want to lose the speed of NVMe. I cannot find any fast NVMe drives that are rated for significantly higher TBW.

Can anyone give me a hint for a good M.2 SSD for write intensive workloads?

Is it possible to combine a 500 GB and a 1000 GB NVMe in RAID1 to expand it later?

Is that a good idea? Can that be Reduced in any way?

yes I specifically decided for an NVMe cache because of the Containers. Maybe That was a Pretty costly decision based on that experience. 😖 I think I'll use the drive until it fails. But from now on I won't have any warning for the point of failure, because SMART already failed. Would adding a second cache drive in RAID1 be a good idea? My Mainboard (Supermicro X11SSi-LN4F) only has one NVMe slot. Will RAID1 work with a PCI NVMe extension?

I aggre to that.

The TBW value also looks pretty high to me so much written and only 1/4 of that read. My whole array is only 1/13 of that amount of data (TBW). Do that sound plausible to you? Additional info: I'm not moving huge amounts of data regularly. But I have quite a few Docker containers (35ea) running, logging writing to Databases and regularly updated.

The RMA Procedure of Samsung is pretty stressful. 🤯 And no advance RMA so pretty much downtime too.

Anyways... You would say the failing SMART test is just because of the prediction and nothing else? And the Prediction is noting I have to be worried about?

I'm not sure about that this website says 400 TBW for all 3 sizes. But I have also read 200 at any place. https://www.samsung.com/de/memory-storage/960-evo-nvme-m-2-ssd/MZ-V6E500BW/
