G-raid removable ssd drives?

H, I have purchased a g-raid removable that has no drives in it can I put in ssd drives? If not is there a limit to the rpm of replacement drives?

ps it is a thunderbolt g-raid

Technically you can put just about any drive in it. However the only ones tested were HGST Ultrastar drives at the time. So any other drive options wouldn’t be officially supported.
