The I/O is not necessarily serialized. When using mmap, pread/pwrite, or asynchronous I/O, the I/O can also benefit from multi-threading given that the underlying storage is a multi-disk array or SSDs using PCIe NVMe (capable of up to 1024 simultaneous I/Os).

Also, I/O calls are likely only to RAM, not to disk, thanks to caching...
