Hi im completely new to RAID and the whole system all together. I have built my own system with a gigabyte x38 DS4 board, which has a built in RAID controller. Currently i have a 750gb SAMSUNG F1 Harddrive. I ordered a seagate 160gb to aid in storing big files. I was thinking about setting up the two as a RAID-0 for extra HD performance. Can anyone tell me, first of all, how to set up the RAID 0, and how big fo a difference do you think i would get?
The odds are that the 750GB drive is faster than the 160GB drive. However, that aside, splitting your OS from your data is not necessarily a bad move, in that if you need to reinstall the OS, you need not worry about the data drive.
My main concern here is that you don't mention a backup solution for the data stored on the 750GB drive. Assuming that the volume of data could grow to the capacity of the drive, you'll want to consider an external drive that can hold it all.
A possible idea is for you to have two 750GB drives setup as a mirror (RAID 1) with your OS and data stored on it. Then have an externel eSATA or USB2 drive for a backup.
You know, your board supports 0/1/5/10 RAID, so you could go for RAID5 with your 750, by getting two more 750 gig drives (avoid that 160 if you want storage). The 750's x 3 together in RAID5 will give you performance of RAID0, but give you parity as well for security against data loss. All together the three drives will give you 1.5 TB storage capacity in RAID5, as you will maintain 2/3rds of the capacity and 1/3 of it goes to parity (so out of 2.25TB from 3x750's, you get 1.5TB storage and 750gigs goes to parity across the drives). Very nice way to get performance and parity with 3 drives, instead of going with RAID0+1 (striped and mirror) which only gives you storage capacity of 2 of the 4 drives, but mirrored, for really high security.
Just a thought. That's the route I'd check out perhaps.
