SATA running Raid0 question

I currently have two 80gb SATA HD's running Raid 0 (so that they act like 1 single hard drive).

My question is: Can I add another hard drive that has more than 80 gigs of space? Or do they all have to be the same size to work properly? (As in, can I have two 80gb HD's and a 160gb HD running raid 0?). Thanks in advance. :D

(If anyone has a link to a thread that already answers this question, that would be appreciated ) :cool:
 
Yes and no.

Yes you can add another drive.
No, you can't keep your existing data.
No, the new drive will NOT operate at anything bigger than 80GB. So, you COULD put in that nice new 160GB HDD into your existing RAID 0, but 80GB of it would be wasted.
 
What you would probably want to do with a situation like this if you are dead-set on RAID would be JBOD
 
Well, technically, you could stripe the existing array with the new disk, and get all 320gb. That would look like this:
Code: 
+----+----+
| 80 | 80 |
+----+----+
|   160   |
+---------+
BUT you don't want to do this. It'd raise the risk of failure even more, and wouldn't gain you much speed at all (in fact, you'd lose more on seeks than you'd gain on linear read speeds.

Oh, and you'd need software raid. I don't know of any hardware raid controller that handles striping a single disk with an array. Maybe if you made a JBOD out of that disk, then added it...

Anyways, the point is, it's technically possible but a really bad idea. Use the 160 to back up the raid0 before you lose data.

 
I know that I'll be losing all my data when I add the new HD. So, the best way to avoid complications would be just to add another two 80 gig SATA hard drives?

Also while we're on the subject of SATA... whats the difference between SATA150 and SATAII? Are they compatable? I can't remember what kind of SATA my mobo is...

Again, thanks in advance.
 
SATAII is a marketing term. It doesn't exist. "SATA II" drives work just fine on SATA ports.

However, almost everyone who uses it uses it to mean that the max connection speed on it is 300MB/s, not 150MB/s.

Not that ANY SATA drive could consume 150MB/s, but if you have an array of, oh, 4 or more drives, I guess it'd be possible to use SATA-3G (The actual term for second gen SATA) and get the most out of it.
