我在别的地方看到楼主的贴子，提到和HP研发沟通的答复：   HP今天给出结论，通电数对寿命无影响，unsafe才是关键指标。 原文如下： It is by HW design, 845 G7 is going through MSC by D3 cold when system entry modern standby , which means SSD power supply will be cut, and resume by PERST#. because the system needs to check battery status so you will see SSD D0 and D3 status change. From drive’s viewpoint, it will become 1 power cycled since it goes through whole power cycling process. Also, this SMART attribute only represents the normal power cycling times, it just a record and does not represent drive abnormality. Power on cycle only impacts traditional HDDs motor. For SSD, only attribute 0D (unsafe power shutdown) increase represents the system is abnormal. 但我这边的硬盘，unsafe power shutdown 数值也是异常高了，1200多次，数据安全存在很大风险。 不是说F2 检测硬盘OK没事了。才短短几十个小时啊，要是硬盘都出现坏块，这个产品还能卖吗。。。 希望这个情况能反馈上去，这个问题潜在的风险还是很大的。
