Raid5(4+1) on 2TB SATA Disks is Recommened on Cx4 120
Hi
I am planning to replace 1TB disks on Clariion Cx4 with 2 TB Disks.
Currently there are 10* 1TB disks on two Raid Groups, both Raid Groups are in raid5(4+1).
Already migrated Luns from one raid group to another.and we are in the process of replacing the 1 TB Disks with 2 TB Disks.(for first raid group)
please let me know, Raid5 on 2TB SATA disks is recommended configuration?
Thanks in Advance.

Consider RAID-6 because of slow rebuilt times (higher chance of double drive failure)
