The KIOXIA NX1 Series features Kioxia\u2019s next-generation, in-house developed controller architecture enabling unique capabilities today while providing a foundation for future features. The new drives are engineered to deliver high-performance, power-efficient storage for GPU-enabled servers and hyperscale data center environments.<\/p><p>\nThe KIOXIA NX1 Series is the successor model of the KIOXIA XD Series, and leverages PCIe<sup>\u00ae<\/sup> 5.0 performance to help cloud service providers and hyperscale operators optimize infrastructure while maintaining operational efficiency. Compared to the previous generation<sup>1<\/sup>, KIOXIA NX1 SSDs deliver up to approx. 38 % higher sequential write performance and up to approx. 20 % higher random write performance<sup>2<\/sup>.<\/p><p>\nAs AI infrastructure continues to scale, storage must keep pace with increasingly dense, accelerator-rich server designs. The E1.S form factor helps maximize storage density while supporting advanced thermal management, including cold-plate-compatible direct liquid cooling configurations that enable efficient heat dissipation in high-performance AI server environments.<\/p><p>\nAdditional features include:<\/p><ul class=\"bwlistdisc\">\n<li>\nAvailable in E1.S 9.5 mm (supports direct liquid-cooling and air-cooling) and E1.S 15 mm form factors (supports air-cooling)<\/li>\n<li>\n1 DWPD (Drive Writes Per Day) for read-intensive applications; capacity lineup from 1.92 TB to 15.36 TB<sup>3<\/sup><\/li>\n<li>\nCompliant with PCIe<sup>\u00ae<\/sup> 5.0, NVMe\u2122 2.0 and Open Compute Project (OCP) Datacenter NVMe\u2122 SSD 2.6 specifications, as well as NVMe Flexible Data Placement (FDP) support<\/li>\n<li>\nBuilt with KIOXIA BiCS FLASH\u2122 generation 8 TLC memory technology utilizing CMOS directly Bonded to Array (CBA) architecture<\/li>\n<li>\nOptional TCG Opal-compliant Self-Encrypting Drive (SED) security model<sup>4,5<\/sup><\/li>\n<\/ul><p>\nThe KIOXIA NX1 Series is currently sampling to select hyperscale customers.

A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 2^30 bytes = 1,073,741,824 bytes and 1TB = 2^40 bytes = 1,099,511,627,776 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, and\/or pre-installed software applications, or media content.
