raid 0 plus raid 1?

post #1 of 18
Thread Starter 
ok so i already have my comp set up in raid 0 and have about 400gb of my 1tb filled and was thinking its about time to back up my comp. so what do you think i should do and can i even do this.

1. get a third hard drive 1tb and set it up as a raid 1 mirroring the other 2.

2. just get and external and do a back up and save all my games and what not on it. but then i'd have to back up manually every time i wanted to save something.
what do you think?

I would go with the first option, but 0+1 requires 4 drives.

I'd suggest you look into RAID 5 if you want to add a 3rd hard drive. Or if you want a RAID 0 mirror, I think you'd need at least 4 hard drives for a mirror of a RAID 0.

No, all drives have to be the same size in order to use a RAID configuration. You can't combine two 500GB drives to be in a RAID with a 1TB drive.

Yes, RAID 0+1 (10) consists of a minimum of 4 disks.

well i really want something that's not going to fail and it would be nice to save 20 or 30$ by just getting 1 hard drive but i'd rather spend the extra money and get something i know will work if something happens to my raid 0.

Yes, RAID 0+1 is what I was thinking he'd have to do too. But, I believe they all have to be the same size hard drive right?

RAID 1 is the safest route. RAID 0 is more for performance, but doesn't protect you from a loss of data.

Raid 0+1 is your fastest option with redundancy but RAID 5 would be slower but cheaper. You could also do 4 drives in RAID 5 so that if one dies you will still have your RAID, if you have only 3 drives in RAID 5 you will need to replace one if it dies (same with 0+1) before you get your data back. You safest option would be 4 drives in RAID 5.

I personally would choose option 2 because thats what I do. Saves you money and keeps your RAID 0 speeds. Every week I throw my new data from my RAID 0 and F3 to a 2tb WD Green.

Well 1 + 0 is 10 so why not do RAID10?

Raid 0+1 with 4 drives gives excellent redundancy and performance, because you get raid 0 and 1 in the same array.
