Kioxia

Kioxia CD8P-R 15.36TB E3.S NVMe 5.0 x4 Read Intensive

SKU CH-WGHA-M0JNG

E3.S internal SSD delivering 15.36 TB capacity, PCI Express NVMe 5.0 x4 interface and read-intensive endurance with 11.72 GB/s sequential read and 5.18 GB/s sequential write speeds

  • 36 TB capacity stores massive datasets
  • 72 GB/s sequential read accelerates data access
  • PCI Express NVMe 5.0 x4 interface maximises throughput
  • 2,000,000 IOPS random read handles heavy workloads
  • E3.S form factor fits dense server deployments

Data-centre SSD with 15.36 TB capacity

The Kioxia CD8P-R is an internal solid-state drive built for read-intensive server workloads. Its E3.S form factor fits high-density chassis while the NVMe 5.0 x4 interface supplies the throughput modern data-centre applications demand. Condition is new and the drive is rated for one full drive write per day.

Throughput headroom and write limits

Sequential reads reach 11.72 GB/s and writes 5.18 GB/s, so large scans and ingest pipelines run at line rate. Random 4 KB reads hit 2000000 IOPS while writes sustain 200000 IOPS, giving ample headroom for metadata-heavy tasks. The 1 DWPD endurance rating means sustained heavy write workloads will exhaust the budget faster than mixed-use drives.

NVMe 5.0 x4 lane constraints

The four-lane PCIe 5.0 link caps total bandwidth at the rated sequential figures, so throughput cannot scale beyond 11.72 GB/s read or 5.18 GB/s write. Systems limited to PCIe 4.0 or fewer lanes will see proportionally lower performance. The E3.S connector requires a compatible backplane; it will not fit standard U.2 or M.2 slots.

Questions about this item

Will this E3.S drive work in my server that currently uses U.2 NVMe drives?

This drive uses the E3.S form factor and a PCI Express NVMe 5.0 x4 interface; it requires an E3.S bay and backplane, not a U.2 slot.

How do I confirm the drive is performing at its rated 11.72 GB/s sequential read speed after installation?

Use an NVMe-capable benchmark tool to run a large-block sequential read test; sustained throughput should approach the rated 11.72 GB/s figure.

Does the drive ship with a heatsink or mounting hardware for the E3.S bay?

The drive weighs 3.88 oz and measures 0.3 by 3 by 4.4 inches; no heatsink, screws or caddy are included and must be sourced separately.
