2x Raid 0 SSD arrays, and Drivepool


Question

Hi, first post here.

I want to create a pseudo RAID 10 ssd array for a Windows 10/Ryzen 5950x based digital audio workstation. Can i do this by having 2 pairs of Samsung 970 evo+ drives running in (software) RAID 0, and using Drivepool to mirror one RAID 0 pair to the other?

(AsRock x570 creator, Asus hyper gen4 m.2 card)

I search around for an answer here and google but could not find it. Any info is greatly appreciated. Thanks.

Unfortunately DrivePool doesn't support Dynamic disks (if I recall correctly it could be added but would require an overhaul of the balancing engine and further work on the duplication code), so it's not compatible with Windows' software RAID implementation.

If your motherboard has even barebones RAID 0 support, that would suffice for DrivePool to "mirror" the pairs.

Specifically, Dynamic Disks add a significant level of complexity, just because of the many different ways that they can be configured. 

This causes issues because DrivePool actively avoids putting files on the same, physical disk when a drive has multiple partitions.  

This detection is done in the kernel, so it has to be fast.  But because of how complex dynamic disks are, this would drastically slow down the driver.

Motherboard based RAID would absolutely work for this.

I appreciate the response from both of you.

To clarify- i would need the motherboard to have 4x nvme slots, and mobo based RAID, and drivepool will mirror one RAID 0 pair to the other?

If the board has 2x NVME slots, and i run a pair of drives in RAID 0, via mobos RAID, would drivepool mirror that pair to another drive, like an NVME drive in a pcie card, or in a thunderbolt chasis?

ie the issue isnt mirroring RAID 0 pair, its if the RAID 0 pair(s) are software raid?

Correct, it doesn't support software RAID (because Windows insists on Dynamic disks for that). Hardware RAID is fine.

All that matters to DrivePool itself, is that it can see the NTFS (or ReFS) volumes on Basic (not Dynamic) disks that are locally (not network) attached to the system.

Doesn't matter whether that's via motherboard or expansion card, PCIE/SATA/USB/Thunderbolt/otherwise, in any combination.
