**But It will slow down NixOS evaluation by factor 2 and increase memory usage.**
|

So if you don't need specialization feature, you can just use hybrid only configuration or nvidia only (DDG only) configuration
|

|

## Using multiple drives with this configuration
|
||||
|
||||
When using more than one drive, the value of `hardware.nvidia.prime.amdgpuBusId` will change from the default of `PCI:5:0:0`.
|
||||
|
||||
Make sure you override this default in your personal configuration. For two drives, it should be `PCI:6:0:0`.

## Setup at the time of testing
