Windows 10: using powershell to create mixed storage spaces

Hi all.
I'm trying to use powershell to create a complex storage space on my 4x6TB HD.
I want to make the first 4TB of each HD in simple pool and the remaining space 2TB with Mirror 2way.
4x4TB Simple
4x2TB Mirror 2Way
This way should be similar to the max speed of Raid0 striped on the first faster TB and the last slower TB with mirror.
I tried with the GUI and it works, but you can't select the columns, so the speed in Simple was low, columns=1...
Making it with Powershell instead it put the correct columns=4.

So I did:
Code: $Disks = (Get-PhysicalDisk -CanPool $True) New-StoragePool -FriendlyName 4xStripe -PhysicalDisks $Disks -ResiliencySettingNameDefault simple -StorageSubsystemFriendlyName "Windows Storage*" |New-VirtualDisk -FriendlyName "UserData" -Size 16TB -ProvisioningType Thin |Initialize-Disk -PassThru |New-Partition -AssignDriveLetter -UseMaximumSize |Format-Volume[/quote] This works as expected, but then I don't know how to add the Mirror pool...

Windows 10 Storage Spaces Improvements?

Here is an example where a 3-way mirror space named VDiskMirrorPS is created on an existing storage pool named Pool01

Optimizing Windows Server 2012 storage management via PowerShell for both performance and resiliency

New-VirtualDisk -StoragePoolFriendlyName Pool01 -ResiliencySettingName Mirror -Size 200GB

-FriendlyName VDiskMirrorPS -ProvisioningType Fixed -NumberOfDataCopies 3 -NumberOfColumns 3

For a 12 column dual parity space his command would be:

New-VirtualDisk -StoragePoolFriendlyName Pool01 -ResiliencySettingName Parity
-Size 200GB

-FriendlyName
MyNewParitySpace -ProvisioningType Fixed -NumberOfDataCopies 2 -NumberOfColumns 12

If you are unfamiliar with managing storage spaces via PowerShell I suggest you create some virtual disks (Disk Management > Create VHD) of sizes maybe 20GB-50GB and spend a long time researching and testing various dummy
storage space configurations. It is the easiest way to understand where the overhead comes from, what column size to choose, what happens when you mix disk sizes, how much space is gained when you add a new disk to the pool, etc.

 

Nokia MixRadio uses lot of storage space

The problem I'm having is that deleting mixes does not always free space. I currently have no offline mixes downloaded but MixRadio is using 322MB of storage and there have been instances of it using over a gigabyte without any mixes.



Downloading a mix and then immediately deleting it does free space so I'm not sure what's triggering it. I typically notice it when the phone starts complaining about lack of free space.
