Although usb-c should easily have enough power for such a device most manufacturers assume you have an older computer.

Okay, now the question is : should I buy 2 x 4TB or 1 x 8 TB ?
Some users says, the ones with 5, 6 8 , 10 TB are very very very sensitive
Is that true ?

I rather have one large drive and then when funds are available setup a second copy for cold storage

i asked about this recently:

https://hardforum.com/threads/are-t...ype-c-front-panel-connector-standard.1996076/

and the consensus seemed to be that the new type C standard connectors do not imply any improved power delivery specification - such that an external drive vendor would be able to say; "right, now i have a minimum of 12.5w to play with, where before i could assume no more than 5w..."
Right. The higher optional power specs are mainly for charging, not peripherals. Though a peripheral could be designed to use either USB if sufficient power available or its own power supply if not. But that would cause confusion. "Why does this drive work when I plug it into X but not when I plug it into Y?"

It's funny how the "Universal" Serial Bus has collected so many confusing or sometimes conflicting asterisks over the years.

I remember in the early days we used to joke that it was "useless serial bus".

At least that part has been fixed.

back in the day, some portable hard drives came with a cable with 2 USB connectors, one was used for additional power if the PC couldn't power the drive with 1 USB connection.

I think 5TB is the largest 2.5" spinning drive you can get right now.
