Update 2: 原po主联系了三星, 得到了如下惨不忍睹的回应 "Our team leader here asked me to make sure that you understand that our OEM customers use their own tools for qualifying and testing NVMe (and other) drives. We do not typically provide to them, so there is nothing that I can send to you for secure erasing the NVMe drive." 三星没有对速度异常做了任何解释, 他提醒购买者该产品不会享受到任何三星售后服务.
