Yes, but it doubles your chances by having the possibility of a drive failing.

what do you exatly mean by sensitive data, i dont want to store only audio + video files on it (can't think of any non sensitive data)

edit:
if i dont do raid 0 i'll go with 1 1tb and buy another one later when i got more money to spend.
By sensitive data I mean files you don't want to lose if a disk breaks. Creating backups helps with that problem though.

As I said, you want max performance? Go for 2 500GB RAID-0. You want max safety? Go for 1 1TB drive.

Wrong. Max safety, go with 2 drives in a RAID1 since we are discussing 2 drive options here.

Obviously the OP wants 1TB of space, in first post he tries to decide between having two drives that add to 1TB, and 1TB drive.

He said he "might" get an extra 1TB drive later, but in the meantime, we are talking about one 1TB drive vs two 500GB drives.

If he does RAID1 on the 500GB disks, he will only have 500GB. I do not think that is his intent.

Or if he bought two of the Samsung F3 1TB drives for the same cost as the 2x 500GB WD Blacks, he could have the RAID1 for security AND have faster speed than those WD Black 500's can give him.

Yeah, but that is not what he asked for. He gave two options.

That doesn't make my suggestion WRONG in the context I answered.

Actually, yes it does.

2 drives in a RAID1 will ALWAYS be faster (with sequential reading) and more secure than 1 single drive. Actually, get this...they're twice as secure.

You suggested 2 1TB drives, but then said that only 1 drive is more secure. And that is wrong.

2 F3 1TB's in RAID0 are fast....FAST
2 F3 1TB's in RAID1 are still faster in reading, but you have security.

And those F3 1TB's are the same cost as the 500GB WD Black drives, and they're faster.

Sorry, the 2 1TB drives was a typo.

Fair enough.

Point still stands though. He's looking at 2x WD Black 500's. Why not get a faster drive with twice the space, for the same money? If he's getting 2, why not get 2x 1TB drives as well then, since they're the same cost? He could then choose RAID-0 or RAID-1 himself.

I actually have 4x 320GB Western Digital Caviar Blue's in RAID 5 and while they are very very fast and very very safe, which definitely helps because I use them as my Page File, Storage and for my Games. However, having RAID setups can sometimes be a pain because if you want to switch to another motherboard, you can't just simply move your HDD's over, you need to back them all up first because once you add them to another motherboard all of your files will be deleted :\\. Also sometimes the software RAID itself can fail on the motherboard itself, which is another danger.

In the end I went with my RAID 5 setup because it was fast and safe and I would recommend it to anyone. I actually came to this setup from originally having a 2x 320GB RAID 0 setup which while fast, I wanted that extra security... Also don't worry about RAID if you have never done it before, its a piece of cake! Go with the RAID 0 setup, you wont regret it (unless of course your HDD's fail) ...
