I am debating between those Western Digital portable drives that go up to 5tb that function with USB only (WD my passport) and the bigger ones (eg my book) that are bigger and need power outlet besides the USB connection.
Is there any difference in quality or durability to store media?


That makes sense. And do you know between Mybook and Elements what is the primary difference? Besides the looks of the outer casing.
There may have been a difference at one point before WD realized what people were commonly using these for, but I was previously using 5 shucked Elements and one MyBook (all 8TB) bought between 2018 and 2024 and they were all the same white label drives.
