Can HDDs be On 24/7...?!?

[rana_kirti]

Hi,

I had a question regarding the operation of HDDs. Is it safe/alright to keep a HDD running 24/7 ? If for example you had a HDD with Data which you only need to access maybe twice or thrice a week then would you...

1. Keep it inside the CPU Case and let it run 24/7

or

2. Keep it outside in a separate External HDD Enclosure ?

So basically i'm trying to ask is it ok keep HDDs running 24/7 even if you don't need to access it very often ? How many hours is a general life span of a HDD and does running it 24/7 cause more wear and tear than keeping it in an external HDD and only switching it ON when needed ? Is it more reliable to keep a less often used HDD in an external enclosure ?

Regards,

Rana.

Depends on how lucky you are. Better to keep outside in a separate external HDD enclosure and use him just when you need , like an external HDD.

That is a big advantage of the WD Greens. They switch themselves off when they are not being used. OTOH, two of my systems use WD Blacks for boot drives. They pretty much run 24/7.
