- I have a WD My Passport 4TB 2.5" USB3 HDD (bus powered). I've been using it as network drive connected to the USB2 port of a Pi3 for 18 months now.
- Over the last few months I'm hearing clicking sounds and I've had to "Check" the filesystem in Linux GParted. That fixes things for a while but the clicking is still there. Once or twice the drive became unusable and it had remounted itself as read-only.
- I'm guessing that I should have been connecting it to a USB3 port and maybe also externally powering it.
- I read that external USB drives draw max current at spin up. I could not find information about this for the WD My Passport drive but I read that some can require up to 1.2A on spin up.
I'm thinking of getting this Ugreen USB3 hub as well as a 5V/3A power supply and maybe a new WD My Passport 4TB 2.5" USB3 bus-powered HDD as well! Let's say the WD My Passport drive does use 1.2A at spin up.
- If I use an externally powered USB3 hub will the drive get enough current required during spin up or will it still be limited by the USB3 spec of 900mA per port?
- If the limit is always going to be 900mA per port then why do manufacturers make bus powered USB3 drives that may require more than 900mA?
- What would be the best solution for me? I thought of switching to a Sata SSD connected to a Pi 4 USB3 port since they require far less power at all times? I have a 1Gb LAN which I read will limit the speed benefit of SSD accessing it over a network but they are more reliable than HDDs it seems?
