We have hard disk drives which present our persistent storage or as they're called our capacity devices. And then we have SSDs, providing a read cache and a write buffer. And so in this configuration, and by the way you have lots of options here. You can have up to seven capacity devices or as little as one capacity device. If you go with an all flash configuration your capacity devices can be SSDs. There's all different ways that you can set up these disk groups.
