RAID 10 for performance, best for read and write, otherwise RAID 5 will be sufficient.

Just make sure you DO NOT create a RAID Array larger than 2TB - 512 bytes, this is the largest that ESXi/ESX supports.

Sir,Thanks for the reply, shall i go for one RAID5 for total 06 disks or shall i go for RAID 10 if RAID 10 how much space will be available for the VM and data, pleas help.
you have to make a decision about performance versus space?

what size are the disks?
If you use RAID 1, the performance will be faster for read and write, operations, but there will be less space for virtual machines. If you use RAID 5, there will be more space for virtual machines, but the performance will be slighly less for virtual machines.

It's a choice between more or less storage and performance.
