I have a Rootserver 4x2TB Sata2
Currently their is just 1 HD mounted and on this their is every data. (1TB)
I use this server as streaming hoster and currently i have the problem, that the I/O waittime is allways 100%.
I think the solution is to create a raid so i have better read speed.
I dont want to lose any data on the first HD, so should be doable without loosing data.
