(RAID 5 is a quicker writer than RAID 6.) Without a hot spare, you will also not get the benefit of 'proactive hot sparing'. A hot spare of the same type, 'stepping in' for a failing drive means no loss of LUN performance while in degraded mode. It can also save time over doing a full rebuild when the failed drive is replaced. 0 Kudos Share. Reply. Highlighted. jpmorgan17. 2 Iron Mark as New

Ich stehe nun vor der Entscheidung ein RAID5 mit einer Hotspare Platte anzulegen, oder gleich ein RAID 6. Es geht mir dabei nicht um die Kapazität, sondern eher um die Ausfallsicherheit. Wenn ich nach RAID6 google, finde ich Hinweise dass dies recht langsam und performanceraubend sein soll.

They greatly reduce the impact of monitoring on the array reliability. If a drive has failed in a fault-tolerant (RAID 1, RAID 10, RAID 5, or RAID 6) array, a vulnerability window opens. If another drive fails during this vulnerability window, the data is lost.
