I'm moving a single large file from /mnt/z to /mnt/y on a bare metal Ubuntu 20.04.3 install.
Both disks are capable of sustaining 2 GB/s in writes, and do in other operations, but mv caps out at ~200 MiB/s.
The disks are PCIe 4.0 Highpoint RAID cards with either U2 or M2 drives in RAID 0. Both with NTFS partitions.
What could I be missing?
