currently taking Unraid for a test drive and like it.
But I’ve a few question and looking for some insight.
My setup so far is very simple 2x 3TB HDDs (XFS) and 2x 1TB SATA SSDs for cache (Btrfs).
A single Samsung 970 NVMe is passed through to a windows VM, performance is as expected.
So my idea is to format the NVMe and put several VM disks on this drive, so than I can use the speed for more than one VM.
But after watching Level1Techs video about “Enmotus MiDrive” I’m not so sure I would profit off the NVMe read/write speeds, since the VM disks are gonna be big files compared to all the small bits directly installed by windows/apps.
Or does the file system/vm manager actually knows that only part of the files inside an vm disk are being accessed and so the VM still profits from the underlying hardware?
And if so what kind of file systems is preferable for an NVMe (Samsungs own F2FS, Btrfs or something else)?
Any input is appreciated thanks and take care
