Kioxia has announced the NX1, an E1.S PCIe 5.0 NVMe SSD family designed for hyperscale and GPU-equipped AI servers. It is Kioxia’s first SSD line officially designed to work with cold-plate direct liquid cooling. Absolute throughput and IOPS values have not yet been published, preventing direct comparison with competing PCIe 5.0 data-center drives.. Direct liquid cooling is becoming relevant because GPUs, CPUs and networking components increasingly consume most of a server’s available airflow and thermal capacity. NX1 connects three important market trends—PCIe 5.0 storage, next-generation NAND and liquid-cooled AI servers.
