don’t buy Crucial HDs… have had issues.
i’ve had good luck w/various 5tb drives for back up. seagate, WD mostly. have had a lot of WD drives last forever. also, OWC (macsales.com) for solid state drives.
and some other random external USB drives that have lasted a long time w/o issue.
i back up to raid and also have 2 external 5TB drives as duplicate back ups. had a bad RAID failure with crucuial drives a couple years ago and now i’m over protective of the data and back up redundantly.
for performance for apple… get teh NVMe whatever they are that are just stick you put in the little case or dock. those seem to be great for performance… then back up to something else.
