i haven't had the best of luck with WD, in recent years
i try to buy hitachi, nowdays
but - it changes like seasons
one year, mfg A will be better - the next year it will be mfg B
i think there are groups of engineers that move from company to company - lol
one group makes good stuff
then, another group fills the hole they leave
they make it cheaper
so, it's hard to know what the best brand is
