RAID 0 or RAID 1?

post #1 of 11
Thread Starter 
Should I use RAID 0 or RAID 1? I have important data and I heard RAID 0 is not very good (maybe I should use RAID 10?)

List all the hard drives you have and how much space you are aiming for.
RAID 0 is doubling drive space, with added chance of a failed drive. If one of the two+ drives fail, the entire array is lost.
RAID 1 is taking two drives (say 80gb and 80gb), and making an 80gb HD that has the data mirrored across two drives.

How much faster is RAID 0?

If you have the money and or the drives and data that you don't want to lose I would install 4 drives {HD's} Then you get the best of both worlds. Raid0+1. Two drives will be back up if one stops working.I also see in your specs that you have a 160 and a 40 gig HD. If this is the case you will only see the smallest drive in raid 0

Don't you mean RAID 10? Btw, I can buy a 160GB drive for $50 so it's not really that hard

You can run all 4. Two are back ups and two do the work. This all you will never lose your data. I still think it's 0+1 but I could be wrong. I will lokk that up now and get back to you. You will see faster speeds with the rail 0.

I recommend having a RAID 0 array and having an external drive for a backup. RAID arrays are great, they can double speed while increasing storage and protect against horrible losses in the case of a drive failure. However, something to consider is that when you setup a RAID array, part of the component to that array is the Motherboard (If you are using onboard RAID Arrays). Say something goes wrong with your mobo, you decided to upgrade upon realizing it's toasted. Hook up your Hard Drives and BOOM, you've got nothing. You see when you setup the hard drives on a new mobo you need to setup a NEW RAID array. Effectively this erases everything on the current array. SO, while Raid 1 and 0+1 backup in case of a drive failure, you still lose it all in the event of a major mobo problem. SO, why not just get an external backup drive. A) Everything is backed up B) You can restore your data in the event of either a drive OR mobo problem 3) It's Totally portable so you can share your stuff and LAST) Less Heat produced, Power Required and Case Clutter.

I found this out the hard way.

Good point there. So you could install one more drive in your case and back it up all the time or is there away that it can back itself self up just one more drive?

How about this:
.....................Raid 1 (160 GB)
........................|
...........|------------------|
.......Raid 0(80GB)...........Raid 0 (80GB)



How much % increase will RAID 1 give?
How much % increase will RAID 0 give?

Raid 1 Gives no performance gains and no extra space.

Raid 0 doubles your space and extra performance.
