I have been reading lots of stuff but trying to find out if a raid10 2drive setup is any better/worse than a normal raid 1 setup....I have to 1Tb drives for my data and a seperate system drive, I am only interested in doing raid on my data...
So i setup my initial test like this....
mdadm -v --create /dev/md0 --chunk 1024 --level=raid10 --raid-devices=2 /dev/sdb1 /dev/sdc1
I have also read about near and far but was going to play with this and was wondering if anyone had any insights for 2 drives setup...Thanks...
Raid 10 requires 4 drives. First you would make two RAID 0 arrays, then create a third array that is RAID 1 using the two RAID 0 arrays for it's devices.
With only two drives, your option is RAID 1 (mirroring - proper redundancy) or RAID 0 (striping only - lose one drive and you lose *all* data).
