World Book II, 2TB leaving it on all day and night?

Is this a bad idea? Leaving on the World Book II, 2tb for months at a time? I haven’t done it yet but I want to insure I don’t lose my data when it goes bad from being on for too long.

I’d think that this is what they are designed for.

I’ve had a 2TB blue light in Raid 1 config on for years
