Non-Volatile Memory Express (NVMe) solid state drives (SSDs) are a revolutionary solution due to their high speed and low latency. Despite their high-speed capabilities, without efficient management and optimized read approaches, we will not be able to take full advantage of these high speeds. This is especially important for data-intensive applications, where performance is often limited by the speed at which data can be read from the drives. The studies reviewed show that io_uring is currently the best performing method of reading from disk. To evaluate the advantages of the io_uring interface, a remote storage using it was implemented. The resulting implementation was compared with the existing remote storage of Yandex.Search, which uses Linux AIO.
