Dude, all those cloud services are tough to get data out of. That’s why a lot of them charge an arm and a leg to have it mailed to you on physical media.
If those disks are the big plastic WD externals, they can be easily shucked and used in a NAS—much cheaper than buying the bare drives without the casing for reasons known only to WD. I have 80+ TB across 5 shucked drives, and the oldest has worked perfectly for over 6 years of heavy 24/7 use.
