Online months on all kinds of drives with high read and write speeds 7,000 / 6,800 MB / s they all come with a new standard in the new NVMe 1.4 standard (actually Samsung did not release) and no one has any idea when it went on sale ? the most stinking thing is that the writing rate is double the reading rate! that means something stinks! https://www.guru3d.com/news_story/addlink_s95_series_gets_nvme_1_4_compatibility.html do not understand what the logic is in this? does the drive read the material and transfer to writing that can write at the maximum rate of reading? So why do I have a writing rate about 2 times the reading rate?
