Raid new

RAID 5 / RAID 6 64KB - 128KB    Balances performance and efficiency; avoids excessive small writes.
RAID 10 128KB - 256KB   Best for VMware, as it minimizes RAID overhead and speeds up reads/writes.
RAID 0  128KB - 256KB   Maximizes performance but lacks redundancy.
RAID 1  Not applicable  No striping (mirroring only).
