I'm purchasing or building a mission critical server that will be servicing moderate I/O requests, nothing to strenious. I wanted to incorporate fault tolerance but wasn't sure which would be my best option.
RAID 5 is only software right, or can you buy RAID 5 cards? I understand the overheads wouldn't be that bad on a modern system anyway. Theres definately a stronger reason to run RAID 5 because of its read speed and theres less disc wastage.
Does anyone run RAID 5, prefferably in a critical position, and what is the performance and reliability like, any problems?
