Quel est le RAID le plus rapide ?
En mode RAID 0, tous vos disques durs sont combinés en un seul et même disque, les donnພs sont ainsi réparties entre tous les disques . Si le RAID 0 s'avère plus rapide il a l'inconvénient d'être plus fragile, en effet si l'un des disques tombe en panne c'est tout le RAID qui tombe en panne.
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.
Comment calculer le RAID 5 ?
Le calcul de l'espace dépend donc pour le RAID 5 du nombre de disques par grappe. La formule est (N-G) x S où N correspond au nombre total de disques, G le nombre de grappes et S la capacité des diques.
Quels sont les intérêts d'un RAID 6 par rapport au RAID 5 mais quels en sont les inconvénients en contrepartie ?
Quels sont les intérêts d'un RAID 6 par rapport au RAID 5 mais quels en sont les inconvénients en contrepartie ? Les donnພs restent accessibles mais on notera une baisse de performance jusqu'au rétablissement des donnພs manquantes. Par contre, si la panne porte sur plusieurs disques, vous perdez vos donnພs.
