Any update on WebDAV? Is there a specific issue preventing it being added? It's been a while...

For add-in SATA PCIe cards, you should generally use the default Windows drivers, and NOT the manufacturer ones in most cases. Same goes for NVME. See screenshot. I've experienced the exact issues you describe when trying the official Asmedia drivers with PCIe cards - random issues that all disappeard on letting W10 decide on the drivers.

I would certainly not use W7 in 2022 either, regardless of whether or not users log in... if it's got Internet access, it's too risky. Once you de-clutter W10, it runs very nicely. There is a free tool called "Geek Uninstaller" that can remove programs cleanly, and the newer Windows Store style apps - works very nicely. There are also several tools for removing other clutter if needed, search "Windows 10 debloat".

This is a topic that comes up from time to time.  
Yes, it is possible to display the SMART data from the underlying  drives in Storage Spaces.  
However, displaying those drives in a meaningful way in the UI, and maintaining the surface and file system scans at the same time is NOT simple.  At best, it will require a drastic change, if not outright rewrite of the UI.  And that's not a small undertaking. 
So, can we? Yes.  But do we have the resources to do so? not as much (we are a very small company)

It can't be added. The "RAID" setup presents the resulting drive to the OS as a volume - it has no SMART data. The individual disks may well be accessible as hardware devices, but they do not present as accessible volumes/drives. WD Dashboard works because it is specifically designed to access the relevant hardware at a low level. Each manufacturer does this a little differently, so it's probably not feasible to add to Scanner, which works on a software level.

Personally I use "Allway Sync". 

[1] Yes, it will only move the data from disk 2 if a balancing rule causes it to be moved (if you have disk space equalisation turned on, for example). Otherwise, it will stay put.
[2] You could just set the drive-overfill plugin to 75-80%? Then if any disk reaches that capacity, it'll move files out? Personally, I assign a pair of landing disks for my pools. Two cheap SSDs where incoming files get dumped. DP then moves them out later, or if it fills up. Note that the disks should be larger than the largest single file you would put on the pool.
If cost is an issue, you could try the following setup with existing hardware instead:
Install the SSD optimizer plugin Tell DP/SSD Opt. that Disk 2 is an SSD and un-tick the "archive" setting Make Disk 1 and 3 "Archive" drives Change your file placement rules so that only unduplicated files go on Disk 2, and only duplicated files go on 1 and 3 That way, all new incoming files get put on "Disk 2", then later when your duplication/balancing rules engage, it will move the data off of Disk 2 entirely, and duplicate to 1 and 3.
This assumes you do not have "real-time duplication" enabled. If you still need the total capacity of the 3 disks, then perhaps a small investment in a 120/240GB SSD to use as a landing drive might be a good idea, and substitute "Disk 2" with "SSD/Disk 4" in the above setup?

I pass through the HBA for Drivepool. I use Dell Perc H310 cards and the SMART data is all visible, as it should be because my Windows VM has direct access to the HBA.
 
edit: Wrong Chris I know, but hopefully helpful?  

This is part of the problem with the way that the SSD optimizer balancer works. 
 
Specifically, it creates "real  time placement limiters" to limit what disks new files can be placed on.  
 
 
 
I'm guessing that the SSD is below the threshold set for it (75% by default, so ~45-50GBs).  Increasing the limit on the SSD may help this (but lowering it may as well, but this would force the pool to place files on the other drives rather than on the SSD). 
 
 
Additionally, there are some configuration changes that may help make the software more aggressively move data off of the drive.
http://stablebit.com/Support/DrivePool/2.X/Manual?Section=Balancing%20Settings
On the main balancing settings page, set it to "Balance immediately", and uncheck the "No more often than ever X hours" option, it set it to a low number like 1-2 hours. 
 
For the balancing ratio slider, set this to "100%", and check the "or if at least this much data needs to be moved" and set it to a very low number (like 5GBs). 
 
This should cause the balancing engine to rather aggressively move data out of the SSD drive and onto the archive drives, reducing the likelihood that this will happen.
 
 
Also, it may not be a bad idea to use a larger sized SSD, as the free space on the drive is what gets reported when adding new files.

Now I have an image of you having some sort of steampunk mechanical networking setup...

This information is pulled from Windows' Performance counters. 
So it may not have been working properly temporarily. 
Worst case, you can reset them: http://wiki.covecube.com/StableBit_DrivePool_Q2150495

Is this for video editing? If so, you might want to consider larger SSDs for the cache, or using a non-pooled SSD for editing purposes and moving the files when you're done (the file you are creating - the source material will be fine left on the pool as you're only reading).
 

Are you using the beta version (2.2.0.651 or higher) of StableBit DrivePool?
 
If so, do this:
http://wiki.covecube.com/StableBit_DrivePool_2.x_Advanced_Settings
Set "BitLocker_PoolPartUnlockDetect" to "False", and restart the system (or restart the "StableBit DrivePool Service"). 
 
If you're using the release version (2.1.1.561), then this shouldn't b e enabled unless you've done so manually. 
In this case, do you have StableBit Scanner installed? If so, the SMART queries can keep the drive active. Throttling the queries will fix this. This can be set in the "Scanner Settings", under the "SMART" tab. 
 
Also, check the frequency that Sonarr and Emby are scanning the drive.  Also, try turning off the real time detection for Emby, as this may frequently ping the pool. 

I've been testing CloudDrive for this purpose, and it seems to work well. Created a local-source cloud drive, then it can be added to a pool in DrivePool. Not sure about performance vs BitLocker, as I only use it to back up documents and photos.

I believe anything newer then what they provide on their main download is a "use at your own risk"

I use them for Server Backup. Drashna has them in his server as part of his Pool. There is a write-penalty but truth be told, I can not think of many use-cases where one would notice. For spinners, they read like crazy. If it mainly write-once / read many then I would say these offer the best value for money indeed.

Just adding my interest in Mega being added at some point :-)

Well, the Beta includes the normal 30 day, fully featured trial. No need to commit to buying now (but there is a reward for doing so!).
 
The list of providers we've included by default are the main, well know providers. Since this is a public beta, we can definitely add additional providers.
 
As for Mega, it does appear to have an SDK for accessing their services, so it may be possible to add a provider.
I've flagged the request for Alex (in addition to including the SDK link to him).

Either should work either way.  
 
Though, if you only have the two disks, it should allow you to quickly remove the second disk from the pool (at least that's what I've seen in testing). Once done, be able to add the second disk, and it will recheck the duplication status and start duplicating the data right away.

Sometimes it doesn't. 
Maybe the port is question is already being used?
 
But that's why we have the manual list.

This is probably a networking issue.
 
If needed, you can manually specify "peers" on the system.
http://wiki.covecube.com/StableBit_DrivePool_2.x_Advanced_Settings#RemoteControl.xml
 
Once you've added the peers, restart the StableBit DrivePool Service, or reboot the system.

Hi Chris check out xcase.co.uk i got my cases from there and they have been Brilliant my setup is listed in the my rackmount section on here.

...to the Stablebit team. Recently discovered DrivePool and Scanner, and it's basically solved all my storage problems in one go. I had my disks in RAID arrays (RAID 0+1), which was a costly way of doing things! I have two main PCs - an HTPC and my personal one. I got the DrivePool+Scanner combo for both after testing DrivePool for the trial period on my virtual machine box (a ProxMox 3.3 machine).
I have lots of unused 320GB, 500GB drives that just aren't suitable for RAID (size mismatch, manufacturer, speed etc), and DrivePool is going to make them usable!
 
Now looking to put together a new build using DrivePool to fit more drives in to my media server. Currently got 3x4TB drives in the HTPC (was 2 in RAID mirror), but no room for more so it's got to move as my media collection seems to be growing exponentially, thanks to my GoPro and storing my Blurays as straight copy MKVs at 24-40GB per movie. Looking around at various hardware before committing to a case. But it will be such a money saver being able to slot in any HDD I have going spare when I need a bit more space.
 
So a big thank you for you guys - you've made things so much easier and I can concentrate on the hardware I want rather than worry about how to manage the data security. Already got a friend to buy the combo too, and he's just as pleased after struggling with storage solutions - especially having recently lost a 2TB drive that wasn't duplicated... ouch.
