Frequently Asked Questions

The T705 4TB PCIe 5.0 M.2 is designed for mixed enterprise workloads including virtualization, databases and analytics.

The T705 4TB PCIe 5.0 M.2 uses a M.2 form factor with NVMe-PCIe5 interface. Compatible with servers featuring U.2 or U.3 backplanes including Dell PowerEdge, HPE ProLiant Gen10+, and Supermicro with appropriate NVMe backplane.

Endurance is measured in DWPD (Drive Writes Per Day). Check the manufacturer datasheet for this drive's specific endurance rating.

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. Consider multiple drives for larger datasets.
💾
Bulk Cold Data Archive
Storing large volumes of infrequently accessed data.
✗ Not ideal
At ~$147/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 4TB and 1 DWPD you have 7,475,200GB 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.
