Raid 0 Questions.

Alright, I'm currently running Raid 1.

If I run Raid 0 (Striping?).

I'd have 320gb to play around with.

Now. Would I be able to partition a section of it (30-50gb for os and programs).

Also Do you think Raid 0 is a good idea?
Or should I just go as 2 seperate drives ?
 
if you run raid 0, and one drive fails, both drive fials..

whats your plan, do you want speed or redundancy ?
 
Well if you have any data on your hard drives that could not be replaced in the event of a failure, then stay with the RAID 1. If they're just programs or saved games or those kinds of things, I would just go for RAID 0. The other option is to use them separately and back up valuable data every so often. Just choose what you think would suit you more.

Another point to consider is that some tests have shown that RAID 0 adds hardly any visible speed improvement in most real world applications.

The odds of a drive failing are very low, much lower than getting a virus that will take out the whole drive. In the case of Raid1, its redundancy isnt going to help if you get a virus or something that will nuke all your files.
 
You'll be going from RAID1, which offers redundancy to RAID0, which doubles the chances of losing your data. Since you currently have RAID1, I would assume redundancy is important to you - and RAID0 offers none.

The performance gains that RAID0 affords is nothing to write home about unless you consistently have I/O of large files, for eg as in video editing.
 
RAID 0 VS RAID 1

RAID 0

Pros:
Faster Write speeds (IE Streaming data to disk)
More available space

Cons:
1 Disk failure means all data is lost.
N times more chance of array failure from lack of redundancy.


RAID 1

Pros:
Fast or Faster read speeds (With concurrent read enabled controller)
Mirrored Data redundancy, 1 Mirrored Pair fails data is still available.
Rebuild time of failed disk isn't as bad as other parity RAID types.

Cons:
N/2 disks worth of space available. IE more expensive per GB


So...

For streaming data, Edited/Capturing video or large data Temporarily RAID 0 is what you want.

Games, debatable. Over a single disk vs RAID 0 speed is better. RAID 0 vs 1, 1 wins hands down if you can afford the loss of space available.
 
well raid 1 was stock config when I bought my comp

I guess i'l'l just go 2 seperate drives so i get more space in my system 🙂

Add a third drive and run RAID 5- Striping with parity.

Dumbass. Performance (especially with a cheapo software RAID controller) will go right in the toilet.
 
Is it possible to only RAID-0 a small section of your two drives? I would like to create a RAID-0 partition for swap and A/V files, but don't want to RAID the rest of the data on the drives (for data security reasons).
Does anyone know if this can be done?

haven't had a drive fail yet have you...

How do I part my Raid 1 array ?

and have it as 2 seperate drives ?

You need a third drive and some software. Are these drives SATA or ATA?

If they are SATA, the only software I have had work reliably is Acronis.

If it's ATA, you could get the job done with a free utiity from your drive manufacturer.

No such thing as RAIDing part. It's all or none.

it's SATA.
So.. if I were to delete my Array, it'll delete everyone on it ? Not just seperate it.

I have some intel utility managing the array.

every raid 1 I've ever delt with (which admittedly is only two or three), you can disable the raid functionality in bios, boot to one of the drives as a single drive, then format the other. bingo. two separate drives, one of which is blank. just make sure you keep track of which is which.

Wrong, ass. If you don't know, don't post. It's not the greatest feature in the world, but some RAID controller can do this very thing, even the nForce4 built-in controller.

One of us interpreted his post incorrectly, probably me. He originally was talking of going from RAID 1 to 0. My response was with that understanding. Sorry if I misunderstood.
