<p class="MsoNormal">We have many DRBD clusters in production and it has always worked great. Our cluster nodes have always had RAID 5 arrays consisting 6x spinning drives. Recently we started using servers with SSD drives. After some research, we find that
RAID 5 is not recommended because it (supposedly) causes write amplification and shortens the life of the drives. However, we really do not want to give up storage space by switching to RAID 10. We are seriously considering using RAID 0 in our database servers,
and using DRBD as “network RAID 1.” What do you guys think of that? Terrible idea?<o:p></o:p></p>
