For this reason, it's called volatile memory.

因此，它被称为易失性存储器。

It used to be that volatile memory was fast and non-volatile storage was slow, but as computing technologies have improved, this distinction is becoming less true, and the terms have started to blend together.

过去，易失性存储器速度快，非易失性存储速度慢，但随着计算技术的进步，这种区别变得不那么真实，并且这些术语已经开始融合在一起。
