我认为为了哪瞬间的启动电流而备大功率电源不可取。
合理的做法是以时间继电器来顺序启动多个硬盘。
现 ...
目前这方面接触太少了,看到了之前查看一个帖子就是说IDE时代同一条线路上的两个硬盘,可以通过主从跳线来延迟从盘的启动,降低电源的电流的负担。Hard drive manufacturers generally program their drives so that when two are used on the same IDE channel as master and slave, the slave drive delays its spin up by several seconds to offset its start from that of the master drive, and reduce the peak demand on the power supply. 但是sata就不知道了~ |
