WebSo your file system's block size should be set to match so that reads and writes are aligned on sector boundaries. Otherwise you'll have blocks that span 2 sectors, and therefore require 2 sector reads to return 1 block (instead of 1 read). WebBy leveraging the PCIe bus, NVMe M.2 SSDs have theoretical transfer speeds of up to 20Gbps which is already faster compared to SATA M.2 SSDs with 6Gbps. PCIe buses can support 1x, 4x, 8x, and 16x lanes. PCIe 3.0 has an effective transfer speed of up to 985 MB/s per lane which means there is a potential transfer speed of up to 16GB/s. blockchain linkedin learning
