Drive Arrays
JBOD (Just a Bunch Of Drives). Drives used individually. For example you put OS
and Programs on one, you audio on another, and your photos on a third. Some
folks use this, mistakenly, for the next.
Concatenated Drives. Drives connected end to end. When drive one is full data

It means all your data is spread over the two disks,
in rather small lumps called 'stripes'.

Through the magic of manipulating the addressing of sectors of the drives,
RAID can indeed make can make two drives appear as one - all transparent to
the operating system. This can be accomplished in multiple ways for multiple
purposes.
See: http://en.wikipedia.org/wiki/RAID
What you describe
If you're concerned about loss of data and can get by w/500GB, get them
set up as RAID 1. This creates a mirror of the first drive on the second.

FWIW, Steve Wozniak once said that he never turned off any of his computers,

Technically, its better to let them run all the time, as it saves wear and
tear on the drive ha

Jeff,
The better drives now have fluid bearings, the fluid is a cushion of air, they
suffer virtually no wear and are extremely robust WRT shock. Also spinning
drive up and down leads to thermal fatig
True but less so than cycling them.

Spinning them up and down tends to wear out the bearings.

Servers are set to run all the time and many are never really switched off,
most of them have the same consumer drives you using. It only saves
electricty though which isn't much anyway but you do over work the drive
when you keep rebooting it often.
BTW I use western digital drives, a 6.4 to boo
I think, neither.
Keeping it ON 100% time is bad for it.
Turning it on and off every two minuts is MUCH worse.
Keeping it OFF 100% time doesn't damage it at all.
I guess there must be a balance -- like turning it off at night.
Best,
