Kioxia KCD8XPUG12T8 12.8Tb PCIe 5.0 x4 2.5" enterprise SSD

SKU CH-PXY0-HQ61H MPN KCD8XPUG12T8

12.8 Tb PCIe 5.0 x4 NVMe 2.5" enterprise SSD delivering 12000 MBps read, 5500 MBps write, 2000000 random read IOPS and 400000 random write IOPS

  • 8 Tb capacity supports massive datasets
  • PCIe 5.0 x4 NVMe interface enables 12,000 MB/s read throughput
  • 5,500 MB/s write speed accelerates data ingestion
  • 2,000,000 random read IOPS handles heavy transaction workloads
  • 400,000 random write IOPS sustains mixed enterprise I/O

Enterprise SSD for PCIe 5.0 servers

The Kioxia KCD8XPUG12T8 is a 12.8Tb NVMe drive built for PCI Express 5.0 x4 slots in 2.5-inch bays. It targets data-centre workloads that need high sequential throughput and strong random-read performance.

Installation in standard 2.5-inch bays

The drive fits 2.5-inch hot-swap bays wired for PCIe 5.0 x4. Ensure the backplane and riser support the full 5.0 link; older 3.0 or 4.0 backplanes will limit bandwidth. Firmware should be updated before deployment to avoid early-life bugs.

Sustained load behaviour

Sequential reads reach 12000 MBps while writes hold at 5500 MBps under continuous load. Random reads sustain 2000000 IOPS and random writes 400000 IOPS without the thermal throttling seen in shorter bursts. Power-loss protection preserves in-flight data during unexpected shutdowns.

Highlights

  • 8 Tb capacity supports massive datasets
  • PCIe 5.0 x4 NVMe interface enables 12,000 MB/s read throughput
  • 5,500 MB/s write speed accelerates data ingestion
  • 2,000,000 random read IOPS handles heavy transaction workloads
  • 400,000 random write IOPS sustains mixed enterprise I/O

Questions about this item

How can I verify the drive delivers its rated 2000000 IOPS 4 KB random read after installation?

Use an NVMe-aware tool such as fio or nvme-cli to run a sustained 4 KB random-read workload at high queue depth and compare the observed IOPS to the 2000000 IOPS specification.

What ships with the KCD8XPUG12T8 and what must I source separately?

The drive itself is supplied; a 2.5-inch U.2/U.3 backplane or carrier, PCIe 5.0 cabling, and sufficient cooling airflow are not included.

Which capacity variant of the CD8P-V series should I select for a write-heavy database tier?

The 12.8 Tb model provides 5500 MB/s sequential write and 400000 IOPS 4 KB random write; choose it when those figures meet the workload demand.
