RAID: Which is better? RAID 1+0 or RAID 5?
Posted on 2006-10-19
I will be using an HP Smart Array E200i/128 BBWC Controller with hot-plug SATA drives. I am limited to 6 drives in the cage. I have a choice between:
A) 6 drives in RAID 1+0 plus 1 drive as an offline spare (no room for the drive in the cage)
B) 5 drives in RAID 5 plus 1 drive as an online spare
The 2 most important things are performance and reliability / fault tolerance. Which would be best?
each drive will be a 250GB SATA drive (HP brand)
I'm assuming the RAID controller above would be fine for either A or B (is this an incorrect assumption?)
Thanks in advance!
