ZFS: Matching Disks in VDEVs, Mixed VDEVs in Pool

Hello All,

I previously installed Proxmox on (what I thought) was a 4 way RAID0 made of 4 x Consumer 120GB SSD's. They were of two different brands. I am now unsure if I had 4 VDEVs or 1 VDEV with a 4 way RAID0. I had very poor performance, and eventually switched to a EXT4 install that performed much better.

I've tried reading up on ZFS, and just can't clearly understand if it's a good option for me. I don't need any redunancy on my Proxmox root or on my container / VM drive storage. Instead I want max speed. I back up containers regularly to a large spinning pool.

Is this a bad fit for ZFS?

I have a huge mess of paired SSD's, and I want them to present a single pool of storage. I fully understand that if ANY of the 8 (planned) drives go, I loose the whole pool, I don't care.

My general layout idea is this:

I have searched the forums and see how often newbies like myself ask ZFS questions, so I apologize in advance for likely covering tired territory.

Any help appreciated!
