Canonical title: Asymmetric RAID: Rethinking RAID for SSD Heterogeneity
Question: Can RAID use heterogeneous SSD capacity and performance without forcing symmetric participation in every stripe?
Context: Conventional RAID assumes similar devices and lets the weakest member constrain capacity or speed.
Method: Asymmetric RAID distributes data unevenly and exposes different portions of stripe address space to devices for placement according to their characteristics.
Evaluation: workloads=; baselines=symmetric RAID; metrics=capacity utilization; performance; rebuild behavior; results=no quantitative result verified
Interpretation: Stripe geometry can be a placement policy rather than a fixed equal partition.
Reusable lesson: Represent heterogeneous capacity/performance explicitly instead of normalizing every device to the minimum.
Applicability: RAID arrays containing heterogeneous SSDs.
Limits: Preliminary workshop work; accessible primary sources do not provide a complete evaluation, recovery analysis, or numbers.
