I'm looking for some help configuring my computer for Raid 5. I have never used Raid before, simply never cared about the redundancy, caring more for space then security.
I currently am running a P8Z77-V Deluxe motherboard with:
1 - 500GB Samsung 840 (OS and Programs) In Marvell 600 (Navy)
2 - Optical drives (DVD burners) (Blue)
3 - 3TB Seagate 7200 Drives (Data) (Navy and Grey)
2 - 2TB Seagate 5900 Drives (Data) (Blue)
Not Connected, 1 - 3TB WD Green drive, 2 - 2TB Seagate 5900 drive
I was contemplating buying two more Seagate 3TB drives to make a Raid 5 out of of the other 3TB drives replacing the 2TB drives. Is it even feasible with my current setup? I was reading on the manual that if I turned on Raid on any of the SATA ports it was a limitation that is was turned on for all.
the limitation is that it will be turned on for all the ports (depending on which controller you select)at once but again you have to select the drives that you want to put in the array. if your sata controller is set to ahci and not raid already,you will have to re install your os again since your primary hdd containing the os is already set as ahci.
another thing to keep in mind though is that while you set up your raid array,you will lose all the data 'if any' that is already present in it.
So if I am understanding this correctly I am able to say for instance just make a few of the ports as part of the RAID, but all the Intel ports will be eligible (since I want Raid 5 I am unable to use the Marvel's)???
Oh and if for now I just wanted to make the three 3TB drives the Raid 5 can I add more to the pool later without recreating from scratch (formatting the drives)?
