This tempting but unsafe shortcut is not a sufficient remediation for Storage streaming bandwidth under GPU load: Assume the nominal SSD interface speed equals the sustained per-GPU dataset throughput across an entire rack. Observed scenario: Storage planning reports raw array bandwidth without accounting for network, filesystem or GPU ingestion bottlenecks. The governing mechanism is: AI data throughput is limited by the slowest storage, network, host and data-preparation stage under actual demand. The proportionate action is: Measure representative end-to-end dataset and checkpoint transfer rates from intended workers at target concurrency. A direct check is: Inspect GPU idle gaps, dataset read throughput, NIC utilization, storage counters and per-job I/O patterns. The acceptance condition is: Representative workers sustain required read and write rates without unacceptable training stalls or checkpoint delays.
