Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 1988 SIGMOD paper and its five-level taxonomy and comparisons. Earlier disk striping, later RAID variants, controllers, patents and commercial implementations remain separate.
