SharePoint 2013 Search Index Location

I wanted to get the location of where the Index is stored. Yes I guess you can get it just by checking what shares are created but I needed to get it from Powershell.
And heres how:

$ssi = Get-SPEnterpriseSearchServiceInstance
$ssi.Components

Voila!

Took me a while. From the beginning I expected the property to be stored at the Index component somewhere. It acctually has a property called "RootDirectory" but that one was empty.
