RAID Comparison: A Summary
Explore the core differences between RAID levels including throughput, reliability, and capacity trade-offs. Understand how striping, mirroring, and parity-based RAID impact performance and data protection to select the best RAID configuration for specific storage needs.

We now summarize our simplified comparison of RAID levels in the table below.
Note that we have omitted a number of details to simplify our analysis. For example, when writing in a mirrored system, the average seek time is a little higher than when writing to just a single disk, because the seek time is the max of two seeks (one on each disk). Thus, random ...
