Internal vs External data storage

[roaf85]

I guess I have a question in respect to an arguement. Is there an data that proves external data storage is better than internal because internal drives are always on vs external drives.

In a corporate sense I guess the arguement for internal is that it is faster and it is a continual back up system, but what about just regular back ups for home use and small business?

Do you really gain alot in terms of drive failure if you external back up data vs internally? Thanks

Why would internal or external drives be always on?

i know that some cheap usb cradles don't normally turn the drive off

but i have the drives set to spin down in my fileserver and they do turn off when not used
