We conducted our test using a meticulously formatted 1 TB NVMe drive with an Ext4 file system. For a truly representative benchmark, we handpicked a 500 MB file as our sample. The outcome? It was excellent! Our results boasted exceptional performance with a great sequential read speed of 3.0 GB/s and an awe-inspiring sequential write speed of 1.1 GB/s.
