I have a Pi 3B+ which I'm using as a home media server - it has been connected to an old 2TB Seagate HDD (with its own external power supply) for a couple of years and running openmediavault software. It worked nicely until yesterday - suddenly lots of errors when accessing the HDD and it's making strange noises.
Seems highly likely that the HDD is dying, so yesterday I went to Amazon and ordered a 2TB Samsung 870 QVO SSD (2.5" internal drive type), and a SATA to USB adapter. They should arrive today.
However...will the power supplied by the Pi 3's USB ports be enough to get it working without a separate power supply? I've read that the USB ports are good for 1.1A @ 5V so that's 5.5W, and the power consumption of the SSD is supposedly about 4W - but does the SATA to USB adapter use a bit of power as well? Unsure if it'll work.
Electricity is quite expensive here in the UK so I'm keen to have a setup that uses as little power as possible (because I run the Pi server 24/7). Speed is less important to me than low power consumption in this situation.
If the Samsung won't work, is there a different SSD that anyone could recommend as having a better chance of success? Alternatively, would I be better off using an NVME drive instead? I don't suppose I'll get to see its full speed potential in this setting, but that's not important, and I might redeploy it in future anyway, inside the new desktop PC that I'm quite likely to buy in the next 12 months.
