General RAID questions.

post #1 of 4
Thread Starter 
My HDD setup is really messed up right now and I want to fix it.

I want to set up some RAID 5 (Maybe 10?) in my server.

BUT! What I want to know is, will I be able to keep the RAID setup and move it from the server into another computer but keep it RAID and I won't lose EVERYTHING?

(The RAID will be used for storing files, no windows installation will be put on.)

Or do I need all the HDDs to be connected to a RAID card to ensure its going to stay intact and I won't lose everything if I ever have to move the RAID setup from computer to computer.

Hopefully I made enough sense in this post.

Just so you know. My Servers Motherboard is a 'Gigabyte GA-MA78LMT-S2 Rev 3.4'

EDIT: Also with RAID settings and everything will I still be able to use IDE devices?

If you want to move a RAID setup it must be connected to a dedicated RAID card, so you'll have to backup the files while you do the move, unless it is already set up on a RAID adapter.

If you mean an optical drive or other disk drive, then yes you can use those at the same time. If you mean you want to RAID with IDE drives, that's generally not a very good idea as IDE wasn't meant to be used with RAID, so you can't hotswap easily.

As for the RAID 5 vs RAID 10 question, it depends on how much storage you want. RAID 5 gives you more storage (1 drive is used as parity so you get 1 drive less for actual storage.) , but it has slightly slower write times and redundancy. In the meantime, RAID 10 gives you the speed of RAID 0 with the redundancy of RAID 1, but you can only "use" half of your drives ie: 4 1TB drives only end up giving you 2TB.

Thanks for the help!

Looks like I'm gonna have to find a RAID card. I don't want to have to keep backing up everything. >.<

If you don't mind using Linux you could always make a software (mdadm) RAID array.

If your motherboard ever goes belly up you can simply transplant the drives into any board that has enough SATA ports with a Linux install and be back up in 2-3 commands.
