Can POE provide enough power to turn SATA drives? I kind of figured for a NAS it probably makes sense to go with a regular power supply, especially since it’ll be mounted in an easy to access location for drive replacement.
- dingaling 6y ago802.3at specifies max 30W at the output port at 600mA so in theory you could shunt that to 5V and get about 5A after losses. Enough to spin up a 3.5" SATA. But most consumer retail PoE switches are only .3af compliant which give 15W minus transmission losses.
- conk 6y ago802.3bt can provide higher power, easily enough to run a few HDDs but there are few switches on the market that offer 802.3bt. Almost nothing available for the residential/consumer space.
