I don't believe the consumer ones actually have sustained sequential read speed to saturate Gen 4.

- Szpadel 4y agosequential reads are the best case scenario for ssds. writes degrade, as they're first committed to SLC cache before being written to slower tlc/qlc.
- Robotbeat 4y agoGen 5 pcie is ~4GB/s per lane, AMD Genoa chips have 128 such lanes. That means on the order of 500GB/s aggregate throughput, which is comparable to the aggregate theoretical throughput of the 12 channel DDR5 RAM of the Genoa CPUs. In other words, with enough data interleaving between enough NVME SSDs, you should have SSD throughput of the same order of magnitude as the system RAM. The weights are static, so it’s just reads.
