Hi Mike,
Without RAID having / and /home and /data on on separate disks will improve performance, but by how much.?
It will all depend on Hardware/CPU/Memory, and how data intensive the applications you are running
Using certain types of RAID and multiple separate disks can make a significant impact.
There are many types of RAID, it can be used for "Performance" or "Redundancy" or "Combinations"
It's actually a complex subject in terms of "Tuning" & Optimisation", beyond me...
I'm interested in Linux RAID 10,
this gives you a degree of performance boost, and some redundancy, but ideally 4 disks for better redundancy.
