Troubleshooting • Re: Externally powered SSD doesn't work well on RPI4

I thought SSDs typically took more than 1A when running at peak power consumption.

Which one is 0.36A peak?
SATA SSD's rarely take that much current because they don't usually have (or need) the heavy current DRAM cache to get to their claimed 350MB/s or whatever. Higher speed SSDs such as NVME need the DRAM cache to get to their claimed speeds.

Currents drawn for SATA in USB3/uas mode are higher than USB2 mode, basically the faster the SSD goes, the more current it draws.
