Unraid Array - Mix HDDs and SSDs


Recommended Posts

Hi,

 

I am currently using unraid with 2 VMs, one debian vm for a webserver and one windows 10 gaming vm with my RTX 2060 Super passed through. 

 

My Array consists of 4 SSDs (3 Data drives and 1 large parity drive).

 

As you are able to configure on which disk a vm should be stored I am thinking about adding some large HDDs to the array to create a fileshare in a windows vm. 

 

But is that even possible without decreasing the writing speed of the SSDs or do I have another possibility to attach HDDs to a Windows VM?

SSDs in the parity array are not recommended and are considered experimental at this point. SSDs in the array cannot be trimmed, and there is some question whether some implementations could invalidate parity.

 

Put the HDDs in the parity array and the SSDs in cache pool or as Unassigned Devices.
