Are you asking for USB 3.0 specification? if yes, read this. The PSU that you ought to use for the R64 is a 3A 5V, so plenty of headroom to power a USB 3.0 2.5" SSD or HDD. Do read tkaiser's post on armbian detailing the Rock64 power usage with a USB 3.0 drive attached (as well as the JMicron JMS578 bridge sold in the store).
