Before you buy: check the bay and the lanes

U.2 and U.3 drives need a backplane wired for NVMe or an adapter carrying PCIe lanes to the bay - a SAS backplane will not do it. Check your chassis supports NVMe in the slot you plan to use before ordering. NVMe drive prices and form factors

Frequently Asked Questions

The 9400 Pro 30.72TB U.3 is designed for mixed enterprise workloads including virtualization, databases and analytics. Rated 1 DWPD endurance.

The 9400 Pro 30.72TB U.3 uses a U.3 form factor with NVMe-PCIe4 interface. Compatible with servers featuring U.2 or U.3 backplanes including Dell PowerEdge, HPE ProLiant Gen10+, and Supermicro with appropriate NVMe backplane.

1 DWPD means you can write the full 30.72TB capacity 1 time(s) per day over the 5-year warranty period, totaling approximately 56064TB written.

Use Case Scenarios

🗄️
OLTP Database Primary Storage
PostgreSQL, MySQL or Oracle requiring low latency and high IOPS.
✓ Excellent fit
NVMe delivers sub-200μs latency vs 5ms for HDD — a 25x improvement that directly reduces query response times. At 1 DWPD verify your daily write volume stays within endurance limits.
🤖
AI/ML Training & Inference
GPU server loading training datasets or serving inference at high throughput.
✓ Excellent fit
NVMe at 6,900MB/s eliminates storage bottlenecks when loading datasets to GPU memory. At 30.72TB you can store substantial model weights on a single drive.
💾
Bulk Cold Data Archive
Storing large volumes of infrequently accessed data.
✗ Not ideal
At ~$195/TB, NVMe costs 10x more than enterprise HDD for cold data. Unless you need fast retrieval, HDDs or LTO tape are far more cost-effective.

Maintenance & Troubleshooting

Maintenance Checklist

On installUpdate drive firmware
Check manufacturer website for latest firmware. Enterprise SSDs receive updates that fix performance and reliability issues.
On installEnable power loss protection verification
Enterprise NVMe drives have onboard capacitors for power loss protection. Verify in drive logs after first power cycle.
MonthlyCheck SMART/NVMe health attributes
Run nvme smart-log /dev/nvme0 (Linux). Monitor: Media_Errors, Available_Spare, Percentage_Used.
MonthlyMonitor write endurance consumption
Track Percentage_Used SMART attribute. At 80%+ consider planning replacement. At 30.72TB and 1 DWPD you have 57,409,536GB lifetime writes.
QuarterlyReview error logs in server BMC
Check iDRAC, iLO or IPMI logs for NVMe errors, PCIe link speed downgrades, or unexpected resets.

Troubleshooting Guide

Cause: PCIe slot not initialized, missing NVMe driver, BIOS not updated, or U.2 cable issue.
Fix: Check BIOS for NVMe in PCIe enumeration. Update server firmware. Reseat U.2 cable. Verify PCIe bifurcation if using adapter. Test in another slot.
