Checking power requirements - need advice

Hi I would like to use two to three sata SSDs connected to my raspberry pi via a SATA to USB 3.0 connector on a USB hub, however I'm unsure if it would consume too much power and I would need to get a powered hub instead. Do let me know if you think I should get a powered hub or it would be fine just to get a simple hub!

you definitely need powered hub.

since some SSDs can draw even 7W each

7W = 1.2A

just by SSD itself.
