Trying to figure out best build for 100-150 TB of data. (alien.top)

I currently have a Dell PowerEdge T430 with a 20c CPU and 128 GB of RAM running Proxmox. Right now I just have an old 240 GB SSD and 4 4 TB hard drives in RAIDZ-2. I have a Plex server in the cloud that I would like to localize including bringing the data in house. Right now my data footprint is around 170 TB but I am trying to whittle that down to around 100 TB.

I am trying to figure out the best way to store the data for Plex. I use Proxmox for things like hosting game servers and hosting software that I use for work. There are only 8 HDD trays so it is not enough for a 100 TB+ storage array. What would be the best way to utilize the hardware I currently have while adding a large array of storage to use?

Ultimately I would like to utilize RAIZ-2 or similar so I have some redundancy and I would love to be able to expand the array as I add more drives to it since I figure my data footprint will continue to grow. Thanks!

2 vdevs with 10 x 10TB drives in RAID-Z2 would give you around 150TB useable.

So you could do that with one vdev and 10 x 20TB disks, but you wouldn't have as good performance and 20TB disks take a long time to resilver if you have to replace one.
