summary
AWS describes 60% latency reduction and 75% latency variability drop from custom Nitro SSDs built with a power‑fail‑safe journal inside the flash translation layer. io2 Block Express (backed by Nitro and SRD) reports up to 90% lower latency and 4× throughput versus prior volumes; Cox moves ~500 TB, hits ~210,000 IOPS and sub‑millisecond latencies with ~50% DB performance gain. Nitro SSD instances show ~2.7× throughput per TB and real‑time DBs (Aerospike) and Splunk report large latency and query time improvements.
