Hello,
I currently have a new Pi 5 with an unpowered 4-port USB3 hub, with 2 USB3 Seagate disks plugged into it.
Sometimes there will be a mix of up to 8 WD and Seagate USB3 disks, across 2 of the (identical) USB3 hubs, with the plan being to reuse still-working old hardware (cough, $ being tight and all) with a max of up to 8 old USB3 drives "overlayed" and served on my LAN by overlayfs/samba/miniDLNA.
I am unsure what sort of transfer speeds one should expect, any advice would be greatly appreciated.
Thanks !
