Overview

On supported models, you can create storage pools on NVMe and run apps or shares directly from them.

Keep hot data on NVMe and bulk storage on HDD volumes for a balanced system.

Compatibility and prerequisites

Confirm support for NVMe volumes on your exact model and DSM version.

• Update DSM and check release notes for NVMe pool support
• Use compatible NVMe drives and fit heatsinks when airflow is limited
• Plan for RAID 1 or RAID 5 on NVMe depending on slot count

Layout and data placement

Place data that benefits from low latency on NVMe.

• Application data, indexes, and small working sets
• Virtual machines with modest capacity needs
• Leave large media libraries on HDD arrays

Migration strategies

Move data with minimal downtime and clear rollback.

• Create the NVMe pool and a new volume
• Migrate apps by reinstalling to the new volume where supported
• Copy selected shares and verify permissions before cutover
• Keep a rollback path using snapshots and backups

Setup steps

A predictable sequence reduces surprises.

• Confirm NVMe detection in Storage Manager
• Create the pool and choose a file system
• Create shared folders or app locations on the new volume
• Test performance with your real workload

Thermals, endurance, and care

Healthy thermals and write budgets keep performance stable.

• Ensure airflow across NVMe slots and use heatsinks
• Monitor write endurance percentage and plan replacements
• Avoid unnecessary write heavy jobs on NVMe volumes

Monitoring and alerts

Watch logs and health to catch issues early.

• Enable health alerts for temperature and life remaining
• Review monthly and after major workload changes
• Test restore paths for any data placed on NVMe

FAQs

Quick answers for planning NVMe volumes.

• Will NVMe replace HDD arrays - not for bulk storage needs
• Do I need enterprise NVMe - choose endurance that matches writes
• Can I expand later - depends on slot count and model support
