会选择， 自己想一个让她明白consequence的方式。比方说，我就不会再继续跟你讨论

你要在你们的婚姻中定义可以接受的沟通方式。be consistent, communicate your

发帖数: 7955 | 27 从SSD的读写原理来看，alignment跟有几个区无关
The alignment of the SSD is required to assure that a logical sector starts
exactly at the beginning of a physical page of the SSD. Without the
alignment, the sector boundaries and the page boundaries will not match and
sectors will span pages. That would require for a Windows write operation to
clear two blocks in lieu of only one thus reducing the write speed by 50%.
