Anybody can tell me about RAID-Z architecture , cuz i tried to understand it by seach in google but it doesn't clear. I don't know why it can beat raid-5. I know it can prove about RAID-5 Write Hole cuz it has copy-on-write feature for data intigrity. But i don't understand about write full stripe for RAID-Z cus raid-5 when it write , it must create parity for recover. Does anyone can clear it for me?
