IT'S A RAID! Well it could be ...

I just added a second 320 gig drive to the new laptop.

The question is it worth using as a RAID array?

It would be a RAID 1 (duplicate drive) if so.

I don't plan to put anything critical on the laptop, and I have a 120 gig USB drive or a Thumb Drive to copy stuff that I need onto.

So, is it worth setting up the RAID?


Actually it would be RAID 1. RAID 0 is stripped set. RAID 1 is disk mirroring. You might be better simply setting up RAID 0 is make one big disk with an external hard drive as backup. 0 is also the fastest option you can do with 2 disk as well.
Thank you - the entry has been corrected.

I'm somewhat leery of RAID 0 as if one drive goes, I loose everything.
Yah that's the thing. How if you could have RAID 5...but that requires 3 disks which would be a little overkill in a laptop. :xP
I think all raid does is saves you time and aggravation when one disk dies - instead of restoring everything from backups you just get a replacement drive and put it in (hoping another one doesn't die while waiting for the replacement to arrive).
I had switched to using raids ever since my total disk capacity went over 250 gig. Now it's over 1T and I don't want to think how long would it take to restore from backups.
Hmm, be aware that it will kill laptop batteries having a RAID setup. However if it's plugged to the juice wall. Lappies are like addicted to taht stuff from the wall. ;)

Then you're fine. But, even with a RAID setup, you should do regular backups anyways. RAID is designed to fail as HDD's usually do, it's not a get out card for doing backups. :)
If you are able to back up your laptop regularly, then I'd go with no RAID/mirroring on the laptop, and regular backups to your robust hard drive system of choice. There are better ways to use two hard drives.

How do you usually use the laptop? If you do music or video editing, or anything that is sensitive to clock and time, it's good practice to have your system drive be on a different physical spindle than your data drive.

Similarly if you use virtual machines, you should have your VMs live on a different hard drive from your host system. If either of those cases apply, you have two hard drives now, so you're all set.
