Best means of transferring Chia plots from fast storage to slow storage?

[Zerophase]

My current system design has NVME drives in RAID 0 doing plotting. Only problem is there's a bottleneck with going to the HDDs for holding plots long term. I can either just throw plots that don't hit away, or maximize the transfer speed to HDDs to minimize down time. For the NVME and HDD drives which Linux file systems should be used? Would ZFS provide any benefits?

Would a RAID 10 array on the HDDs address this? Can any type of RAID or such similar system be used to speed up HDD performance, while still being able to move HDDs to another machine for farming?
