Raid 5, is really fine as long as all disks are running good. When one disk crashes,, it becomes a bit slow,, if two disks data is no longer available and your RAID 5 is dead.
In this video I am fixing a RAID 5 on a Lenovo x3650 M4 , where two 3TB diskes has died.
My PlayHouse is a channel where i will show, what i am working on. I have this house, it is 168 Square Meters / 1808.3ft² and it is full, of half-finished projects.
I love working with heating, insulation, Servers, computers, Datacenter, green power, alternative energy, solar, wind and more. It all costs, but I'm trying to get the most out of my money, and my time.
