We are digital librarians.

Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

generally is it an acceptable practice to daisy chain USB HDs and SSDs to a powered hub instead of using an enclosure? (alien.top)

I need the mobility sometimes due to work and studies, and I already bought 2-3 external HDs some years ago. for the moment i will have to put up with a usb hub.

i am worried about the safety of data storage though.

could it damage the laptop and the usb ports potentially if i daisy chain 3 usb HDs to a powered usb hub (12v 3a total input, 6 sockets 5 v 900ma (max), 4 sockets 5v 1.5a (max) ), connect that to a 3.2 usb socket, and then use another 3.2 socket for a 1.5a external portable SSD? would that simply demand too much power and cause problems?

I have 3 external USB HDs from 2017s. 3x 1tb WD passport and WD elements.

1 external SSD Samsung 1tb T7.

Plz advice me, thank you!

Power wise you should be fine. But daisy chaining USB is never good practice. You're adding more potential for packet errors and slowdowns. Do it right and get a powered hub with the number of ports you need.

In addition, if you're using more than one device at a time, you're limited to the bandwidth and resources of the port on your PC you're connected to. And the sum of multiple devices is usually less than the sum of the individual bandwidth possible on each device.
