License problem with storage device counting

[ZiemaF]

I am at the UNRAID testing stage. 

I am looking for an alternative to OpenMediaVault (which is also a great platform for building a NAS)
Currently it is a trail. There is no limit on the number of disks here.
Current configuration up to 5x HDD 3TB as Array Device, 3x SSD 256GB as Cache Device.
BASIC license for $ 59 includes 6 storage device.
Is Storage Device only an Array Device (1) or also a Cache Device (2)?
Because I actually store data only on Array Devices, these drives are counted as Storage Device.

All attached disks are counted. Array, Cache, and even Unassigned.

So I would have to buy a PLUS.
It's still going to test it, and I'll probably come back to OMV.
Are there any promotional prices for licenses?

Plus is good for 12 devices.

There have been no promotions in recent times!    One thing that is good about Unraid is that the license (currently anyway)  is a lifetime license covering all future upgrades.

At the moment, the expense of $ 89 is a lot.
The price for the Basic version was still acceptable, but unfortunately I would have to buy a PLUS version and that's too much.
I will keep watching, maybe I will buy one day.
