Stripe parity for RAID 5

I have a HP DL385 G2 that will run an ERP software. I am configuring RAID 5 but not sure what type of stripe parity to select. I usually select 128 KB. By default HP select 64 KB. What stripe parity size should I select for RAID 5?

Thanks

Re: Stripe parity for RAID 5

Hi,
There is no common rule for RAID-5 stripe size. Till 6x generation of SmartArray controllers default stripe size was 16 Kb and since SmartArray 6x default stripe size for RAID-5 is 64 Kb.
128 Kb usually used for RAID-1
