RAID 6 vs RAID 5


Le RAID 6 est une évolution du RAID 5. Il fonctionne de la même manière, mais permet de supporter la perte de deux disques grace à une double parité. Le RAID 6 offre donc une plus grande redondance au détriment de l'espace de stockage puisque l'on perd l'équivalent de deux disques en espace de stockage.

Quel raid est le plus fiable ?

Le RAID 5 est donc bien plus sûr que le RAID 0, mais offre beaucoup moins de performances d'ຜriture/lecture. Ces performance sont tout de même supérieures à celle d'un disque dur seul non RAID.

C'est quoi le RAID 5 ?

La configuration RAID 5, par un système de parité, répartit une petite partie des donnພs sur chaque disque. Dans cette configuration, ce n'est pas la performance qu'on recherche mais plutôt la sຜurité tout en ຜonomisant le volume de stockage.

Quel raid a le plus de performance en lecture et ecriture ?

Le RAID 5 permet d'utiliser simultanément tous ses disques (celui-ci se compose au minimum de 3 disques). Il s'agit d'un système hautement performant en lecture et en ຜriture et offre une grande tolérance aux pannes. Le RAID 5 offre par ailleurs une haute capacité équivalent à N-1, N étant le nombre total de disques.
