Correct. Allocation group is the group of drives that the virtual drives
(workspace in Avid talk) are created from. Unity can have more than one
allocation group. Since it is a virtual drive, the amount of empty space
does not really matter as long as any operation can be executed properly
- such as saving bins and capturing media.
Allocation group is basically just a RAID set, thus "one" big physical
drive, the rule of 10% still applies. Avid recommends 15% empty at any
given time, but the warning does not start until 10% (yellow) and 5% (red).

> For the Unity impaired can you explain the allocation group relationship to a work space? In my mind the allocation group is the number of drives in a particular pool of storage. Then work spaces take storage across all the drives/spindles in the allocation group. This is just in my mind and not based on actual technical fact or terminology am I even close with this? I really need a little Unity 101.

Some of these are large workspaces and they still have 150 to 200 GB available. That's a lot of space free in my book but is the Unity still going to have issues, such as errors or whatever, with the high percentage of use in these workspaces with 150 to 200 GB available. Does the size of the free space matter more than the percentage of the workspace being used? Not having any specific issues right now but I'm being told I can't add media to the work spaces that still have what I consider a lot of free space.
