RAID 0
RAID 0 is the fastest RAID mode since it writes data across all of the volume's disks. Further, the capacities of
each disk are added together for optimal data storage. However, RAID 0 lacks a very important feature for a
NAS: data protection. If one disk fails, all data becomes inaccessible. When weighing performance against
protection, keep in mind that a NAS's transfer rates are contingent upon the bandwidth of the network as well
as its own hardware. For example, with both LAN ports bonded and connected to a router that supports port
aggregation, the 5big NAS Pro cannot exceed 200MB/s. A recommended option is RAID 5, which offers
comparable performance, approximately 75% storage capacity (based upon total available disks and storage
capacities), and data protection.
