Quel est le gros inconvénient du RAID 0 1 par rapport au RAID 5 ?
L'inconvénient de ce type de raid est qu'il faut 2 disques. Et que l'on perd la moitié de l'espace car les mêmes choses sont copiés sur les 2 disques. (Si vous avez 2 disques de 500 Go, vous n'aurez un volume disponible que de 500 Go).
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 avantage apporte le RAID 1 ?
Comme pour le RAID 0, le RAID 1 permet une lecture des donnພs rapide puisqu'elle peut se faire sur les deux disques mirrorés à la fois. En ce qui concerne l'ຜriture, elle est plus lente qu'en RAID 0, car les donnພs sont recopiພs entièrement sur chaque disque mirroré.
