Since SSD has write amplification, I want to reset the SSD to the initial out-of-box performance. Most tutorials are for SATA SSD (hdparm --secure-erase), I want to know how to erase a partition of NVMe SSD (maybe use nvme command?).


One more question: does dd if=/dev/zero of=/dev/nvme0n1 help? Or does fio --filename=/dev/nvme1n1 --direct=1 --buffered=0 --rw=trim --bs=4k --size=100G --numjobs=16 --iodepth=32 --group_reporting --name=trim help?


Thanks!

To totally erase a NVMe drive.


This will erase entire drive.


You may need to first install nvme - the NVMe storage command line interface utility (nvme-cli). Then review commands and list all nvme devices. List wil also show firmware revision & you should check that you have latest firmware.


sudo apt install nvme-cli

nvme help

nvme --help

nvme --help format

sudo nvme list

sudo nvme format -s1 <device>
