12.8TB NVMe SSD for data centres

The Kioxia KCD8XVUG12T8 is a 12.8TB NVMe solid-state drive built for scale-out and cloud workloads such as big data, online transaction processing and virtualization. It uses a PCIe 4.0 x4 interface and 112-layer BiCS FLASH 3D TLC to deliver consistent performance in 24x7 environments. The drive is rated for 3 drive writes per day and targets hyperscale deployments needing high-density storage.

2.5-inch 15mm U.2/U.3 form factor with single port

The drive fits a standard 2.5-inch bay at 15mm thickness and uses a combined U.2/U.3 connector for a single-port NVMe link. Power-loss protection and end-to-end data correction guard data integrity during unexpected outages. The proprietary Kioxia controller and firmware are tuned for steady throughput under sustained mixed-use loads.

Check backplane and thermal provisions before

Verify that your backplane or cabling supports a U.2/U.3 NVMe device with a PCIe 4.0 x4 electrical connection. The 15mm z-height requires a drive bay or sled that accommodates the thicker profile. Ensure the system can supply adequate airflow for continuous operation at the rated endurance level.

Questions about this item

What does the PCIe 4.0 x4 interface cap at in practice?

The PCIe 4.0 x4 interface runs at 16 GT/s and delivers up to 1,250K random read IOPS and 380K random write IOPS in this drive.

What physical space does the 2.5-inch 15mm U.2/U.3 form factor need?

It requires a 2.5-inch drive bay that accepts a 15mm thick U.2 or U.3 connector.

How is the drive installed and what step is often missed?

Slide the drive into the hot-plug backplane until the U.2/U.3 connector seats firmly; the step often missed is not pushing it in fully so the latch clicks.
