Calculate total usable capacity and performance of a RAID 0 striped array.
RAID 0 stripes data across all disks with no parity or mirroring, so 100% of the raw capacity is usable. While this maximizes storage efficiency and sequential throughput, it provides zero fault tolerance — any single disk failure results in total data loss across the entire array.
RAID 0 usable capacity
usable = n × disk_size
RAID 0 is suitable for scratch/temp data, caches, or workloads where performance matters and the data is easily recreatable — never for data you cannot afford to lose.
Yes. Read and write throughput scales roughly linearly with disk count because I/O is spread across all members simultaneously, making it the fastest RAID level for sequential workloads.
