Raid 0 with 3 HDs?

[MrGrim]

Hi, I have an Asus A7V133 with onboard Promise RAID controller. I've currently got a 2 HDs Raid 0 setup and I was wondering if I could add another one.

Would it work? Would it be ok for 2 HDs to share the same IDE port?

TIA

I think you have to have an even number of drives, i.e., 2 or 4.

[edit] sorry, I guess I was mistaken.

My promise card supports RAID 0 with three drives, don't know about the onboard, 2 drives can share a channel, they just can't talk at the same time.

So the performance will be the same but there will be more space, right?

 

[rbV5]

Actually, it should be faster than 2 drive RAID and have more space.

In some cases a 3hd raid setup is actually faster than a 4hd setup. To answer your question, yes you can add another hd. Just a reminder, try to make sure it's the same as the other two, you will also have to redo the raid setup.... There will be a performance increase, wheather it's seat of your pants or not is another thing...

Wouldn't two drives on an onboard IDE raid controller be faster than 3? 3 drives would mean that two drives are sharing a controller. Wouldn't this cause it to slow down since only one drive can read/write at a time?

you might be able to pull it off but I wouldnt recommend it. Remember, the risk of one drive failing and causing a catastrophic data loss is proportionate to how many drives you run in RAID 0.

Yes, it is faster. Go to Storage Review and look at the articles. Three drives just about saturates the bus and four completely saturates it. Have fun, but follow the posted speed limits before you get yourself in trouble. 🙂

Cool, thank you all for your replies. 🙂
