For instance, on Fedora, CentOS, or similar: $ sudo dnf install nvme-cli You can install nvme-cli from your distribution's package manager. Those questions led me to an Internet search that yielded an open source project with a collection of tools to manage NVMe drives. Could I securely erase the drive? How could I check its integrity? That was interesting, but I wanted to know more about my particular NVMe drives, and I wanted to know how they compared with other drives. I learned that NVMe drives consume less power while delivering much faster access to data compared to even SSD drives over SATA. It also didn't take long for me to get curious about the technology driving this ultra-fast storage, so I did a little investigation. I love how quickly my computers boot and how quickly they're able to read and write data. My laptop has an NVMe drive, as does my desktop.
