So are the Anvil tests the only ones that do substantial random read/write? These benchmarks seem opaque. Last I really dug into SSD benchmarking, sequential was usually quite gaudy for a lot of SSDs that were seeking benchmark placement, but the real advantage of SSDs over HDDs was random access and IOPS. IF this is such a massive improvement, is this mostly due to: - PCI bandwidth utilization? - 8nm silicon? - controller algorithm/efficiency? It's my impression that controller algorithms have peaked after the first couple iterations of consumer SSDs, so we'd be left with either bandwidth or silicon. And how less durable is 8nm cells, since flash at a theoretical level becomes more fragile with each node shrink?
