There's plenty for RAID in general, but I do not know of any in-depth Solr-specific guides.

For index updates, you want high bulk read- and write-speed. That makes the striped versions,
such as RAID 5 & 6, poor choices for a heavily updated index.

For searching you want low latency and high throughput for small random access reads. All
the common RAIDs gives you higher throughput for those.
