Hi,
Please try the command and share the result for reference:

// Direct write
$ sudo su
# echo 3 > /proc/sys/vm/drop_caches
# fio --filename=/mnt/testfile2 --direct=1 --rw=write --bs=10m --iodepth=64 --size=60G --numjobs=1 --time_base=1 --group_reporting --name=test-seq-write --ioengine=sync

// Buffer write
$ sudo su
# echo 3 > /proc/sys/vm/drop_caches
# fio --filename=/mnt/testfile2 --direct=0 --rw=write --bs=10m --iodepth=64 --size=60G --numjobs=1 --time_base=1 --group_reporting --name=test-seq-write --ioengine=sync

On AGX Orin developer kit + Samsung 2TB NVMe SSD card, direct write is 3735MiB/s and buffer write is 1145MiB/s
