RAID hardware vs RAID software

hello people, i've a doubth; I've a DELL server Poweredge, with 2 hdd sata in RAID1 hardware by internal controller . For good performance , i must install proxmox 6.4 on disk RAID1 disk selecting ZFS RAID0 , or better erase RAID1 hardware and install proxmox in ZFS RAID1 on these 2 free disks ? Or create 2 RAID 0 hardware and than install proxmox in ZFS RAID1 on it?

thanks , have a good weekend :]
