Comment on Moving to OrangePi Zero 3, what are my storage options?
opulentocean@lemm.ee 6 months agoQuick question about the hubs. I saw some with 5+ ports. Using USB 2.0 I know I’ll have some limitations on speed, but could I for instance, plug 5 HDDs and this speed would be evenly divided among then (given a moment where they all would get written at the same time)? If only 1 HDD is being written, would it get this full speed? Is this math that simple or are there more things that I’m not considering?

devices on the hub share the total bandwidth to/from the host system's usb port. data going between drives on the same hub has to travel to the host then back again.
so: transferring files to/from a single drive will go 'full speed', transferring files between two drives on that hub will run at about half speed, accessing data on all the drives on that hub at the same time (such as syncing a snapraid array built on externals all connected to that hub) will be painfully and brutally slow.
