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?
i would avoid smaller wd external hdds, the big ones or seagate ones have sata hdd inside, but those wd ones are usb-only. you get to trash the drive if the converter fails (which is pretty common)
also consider getting larger enterprise 2nd hand drives, those are pretty cheap and nice
Where do you get those?
i believe it really depends on the region you’re on sadly :(
i live in a fairly small country and i usually source my drives from a marketplace in some server related internet forum, maybe there’s something similar. i guess you gotta try stuff like ebay, facebook marketplace or your equivalent local 2nd hand market platform.
