To rule out obvious problems with the SSD, what happens if you copy similarly sized files from one directory on the SSD to another on the SSD?On a headless Pi5(Bookworm64) with NVME drive and a NAS directory mounted on the Pi5 if I attempt to transfer a large file >6GB from the NVME drive to the NAS directory the system hangs. What happens is initially the transfer is very fast then as the transfer approaches 6GB it slows down eventually it grinds to a stop. The NVME drive gets very hot and remains hot. At the same time SSH terminal access to the Pi grinds to a halt.The disk access LED on the NVME Hat continues to flash and a ping continues to run with a ping time of <1ms. So the higher level functions have ceased but the system has not hung completely.
The link to the NAS is via wired 1Gbps Ethernet. Transfer of large files from the NAS to the NVME drive is faultless!
To guide others to reproduce your problem, are use connecting to the NAS using CIFS or NFS? Do you know what protocol level is being used?
