Many External hard drives from across many different brands, tend to fail over time. how reliable is this HDD ?.. How long is it expected to last. I plan on Using it for my xbox one, and as any gamer would know loss of data is like the plague! As far as it being a AC powered, is it safe to leave plugged in, or can it be unplugged when not in use ? If I am correct the Hard drive has a power button, is it safe to turn the hard drive off when not in use without corruption of data. Also if the power goes out to lets say a power surge protector which the hard drive would be plugged into will the hard drive be ok, and not lose data ? or every time the power shuts off to the house because lets say your normal power outage will the HDD be safe ? or will loss of data or corruption occur ? The struggle with hard drives is if they fail, or become damaged.. data is loss which money can not replace.. and the HDD is not cheap in general!
