Consider RAID-6 because of slow rebuilt times (higher chance of double drive failure)
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.
Raid5(4+1) on 2TB SATA Disks is Recommened on Cx4 120
