Sadly i can't do like Raid rn because you can't run Raid of an USB. Anyone got help like buying a PCIe board for HDDs.
There's nothing in Linux stopping you. Certain distributions/NAS software (Open Media Vault for one) won't permit it but it can be done in the same way as on any other block device.
Just remember that RAID is not a substitute for backups. It protects against hardware failure and improves availability but it doesn't protect against other forms of data loss such as human error.
As for Murph9000's suggestion of switching to NVMe, unless you have money to burn and a strong need for fast random IO or an equally strong need for physically small and silent, it probably isn't worth it. The performance limit will be the network and decent spinning rust can saturate that. Unlike the 4B, the Pi5 has enough bandwidth between SoC and USB controller to run both USB3 ports at maximum speed. It doesn't have enough bandwidth to run most NVMe drives at maximum speed due to the single available PCIe lane and adding a PCIe switch and second NVMe will cut write bandwidth per drive in half.
