Hey guys...
I'm planning on building a PC sometime next month... and I'm thinking of getting 2x 1TB WD Caviar Blue HDD (Because 2TB wasn't available)

Since I was getting 2 HDD, I was wondering if I can get the 2 of them to work in RAID 0 setup...
So is there a way to do this in the bios... before I install my OS...?

If yes, then how?

I'm guessing once you have the OS, it's not gonna be easy to setup RAID cause it'll probably need to format and stuff right?

Yes, you can create a RAID-0 array with your motherboard's BIOS.
Read your motherboard's manual for instructions on how to do it.

There's no need to format the drives before you create the RAID array.
After you create the array you can let Windows automatically format it during the installation process.

FYI, there's no fault tolerance with a RAID-0 array, so if one of the drives in the array dies then you will lose all of your data.
So make sure you have a backup plan in place.

Are faults really that common? I mean... if had just gotten a single 2 TB drive, I would basically run into the same problem right?

Or does RAID make it even more prone to faults or something like that?

Statistically Yes raid zero is less fault tolerant than a single drive. This is because you now have like double the chance of failure because you have two dependant drives. However, I work in an enterprise size organization doing desktop support. We would never do this, but that being said the chances of either of your drives failing in the first 3 years is extremely low. That is just my experience. If it were me I would be a single 2 TB HDD. But that is just me.

Clide005 is correct. There's nothing about a RAID array that will cause your drives to fail, it's just that your odds of failure increase.

I have had 2 HDDs in RAID-0 since 2007 without any problems, and 2 SSDs in RAID-0 since 2009 without any problems.

If you have data that you can't afford to lose then you should have a backup drive regardless of whether you have a single drive or multiple drives in RAID.

I found that out the hard way in 2004 when I lost about 6,000 mp3s when my HDD died and I didn't have backup. :)
Since then I've been pretty religious about backing up my data. :)

Hmm... I'm quite on a budget...
So I don't think I'll invest in another HDD purely for backup purposes...

So, I'll get a single 2TB HDD...
How's the Seagate Barracuda SV-35 2 TB HDD (ST2000VX000)?

The only WD 2TB HDD I could find online (within a reasonable price) in Inida were Green series... which are quite slow right? Not good for keeping as a boot drive... that's what I heard...
