I have a raid 5 array of 4 disks amounting to approx 5.5tb. Now this = disks are getting a bit long in the tooth so before I get into problems = I=E2=80=99ve bought 4 new disks to replace them. I have a backup so if it all goes west I=E2=80=99m covered. So I=E2=80=99m= looking for suggestions. My current plan is just to replace the 2tb drives with the new 3tb = drives and move on, I=E2=80=99d like to do it on line with out having to = trash the array and start again, so does anyone have a game plan for = doing that. Or is a 9tb raid 5 array the wrong thing to be doing and should I be = doing something else 6tb raid 10 or something I=E2=80=99m open to = suggestions. Cheers Jeff=
