使用Memcached存储PHP变量是否涉及写入硬盘驱动器？

Question

Since this is what I am trying to do. I want to make some variable values available to a PHP script. The values are fetched from the internet every minute (they change). I do not want the values to be written and written again to the SSD. Does Memcached do the job of storing them at any given time on system memory only, with no SSD writing? Thanks.

Answer 1

As the name implies, memcached only stores things in local memory. If you restart the service any data inside is lost.
