Overview
The Kioxia LD4 Series is Kioxia's first E1.L form-factor enterprise SSD built with BiCS FLASH generation 8 QLC flash memory. It is purpose-built for the high-density 1U servers and scale-out environments that dominate hyperscale and AI data-centre storage tiers.
By moving high-capacity QLC NAND into the E1.L ruler form factor, the LD4 lets a single 1U chassis carry far more flash capacity for read-intensive workloads — dataset retrieval, content delivery, analytics and AI data lakes — where read bandwidth and capacity density matter more than write endurance.
The drive is offered in 15.36 TB and 30.72 TB capacities today, on a validated architecture that scales to 122.88 TB. It is single-port, NVMe 2.0e compliant and follows the OCP Datacenter NVMe SSD Specification 2.6.
Key Benefits
Capacity density: E1.L ruler form factor fills 1U scale-out bays with high-capacity QLC. Proven flash: BiCS FLASH generation 8 QLC NAND. Hyperscale-ready: single-port OCP 2.6 design for cloud-class servers. Genuine PCIe 5.0 class: Gen4 x4 link with NVMe 2.0e compliance.
Applications
Hyperscale and cloud data-centre storage tiers, AI dataset and data-lake storage, read-intensive content delivery, media archives, analytics and scale-out object/file storage.
