Hello everyone, I currently have four USB 3.0 drives connected through its own USB hub to save space. The issue is that they sometimes vanish unexpectedly, so I need to disconnect the hub and reattach it. Is it a good approach or would using a powered USB 3.0 hub be better? This setup is compact, and adding more USB ports isn't possible.

USB 3.0 is limited to 0.9 amps at 5 volts, meaning it requires more than that if it tries to draw more current. Hubs might also experience performance issues at times. Edited July 23, 2023 by thrasher_565

It's generally advised against using hubs for running drives, as they can be unreliable even with powered options. Success has been limited to drives with dedicated power sources and favorable hub compatibility. Keep in mind that a single drive might monopolize the USB bandwidth if connected to the same hub, leading to reduced performance. For portable setups, consider devices like the Icybox 4 or 5 bay JBOD, which work well with SATA drives. I use two of those for my NAS backup drives, each on separate USB controllers to avoid conflicts. Notably, most of these were sourced from USB 3.0 HDDs, typically internal SATA devices.
