how many disks needed for raid 5??
I came across this question, asking myself every once in awhile when ordering new hardware. How many disks are needed to setup a server with RAID 5 configuration?
Here is a visual of how many you need…. 🙂
The minimum is 3 but it’s recommended to get 4 disks of similar size/type and the 4th one can be used for parity.
i think raid5 performance is maximum with 5 disks
it is a distributed parity
so you can not use a single disk for parity
