Show Notes
In this technical deep dive, Herman and Corn explore the complex world of Redundant Arrays of Independent Disks (RAID). Inspired by a listener's "Frankenstein" workstation setup, the duo breaks down the trade-offs between performance, capacity, and redundancy across RAID 0, 1, 5, 6, and 10. They go beyond the basics to discuss the terrifying reality of rebuild times on modern 30TB drives, the mathematical magic of XOR parity, and why software RAID and ZFS have overtaken traditional hardware controllers. Whether you're a video editor looking for speed or a sysadmin guarding against bit rot, this episode provides the essential engineering insights to keep your data from vanishing into the void.
