Hi all,
I have so far read 3 different versions on the best type of raid level to use (differs amongst us here as well) So I thought I would give all you great people a chance to throw in your 2cents worth.
a- Raid level 0 - Stiping no redundancy. Cost Best, Availability poor, Performance Good
b - Raid level 1 - Mirroring - Cost Expensive, Availability Excellent, Performance good for reads poor for writes.
c - Raid level 0 + 1 - Striping with mirroring - Cost Expensive, Availability Excellent, Performance Best
d - Raid level 3,4,5 - Variations on Striping with redundant disk - Cost good, Availability Good, Performance Good
e - Raid level 5 - Striping with xor across all disks - Cost good, Availability good, Performance moderate.
There are other levels but I would rate raid 5 as the best performance but not according to the information above.
What other opinions are there? What do you recommend as the BEST PERFORMANCE raid with at least good availability?
