# Best Hard Drive for Immich: NAS Storage Buying Guide for Large Libraries

Canonical: https://cloudzat.com/best-hard-drive-for-immich/

Purpose: Immich storage buying guide.

Decision: For a growing Immich library, favor internal SATA NAS or enterprise hard drives with a clearly identified capacity and warranty, then size the pool around future usable capacity rather than today’s folder size. Keep database/application data on local SSD storage and treat the HDD pool as the economical media layer.

- Growing library: NAS or enterprise SATA HDD — Choose a clearly identified model and capacity, then plan the pool around usable space.
- Array workloads: Prefer verified CMR — For RAID, ZFS and sustained rewrites, confirm the exact model’s recording technology.
- Capacity planning: 12TB–24TB tiers — Higher capacities can preserve bays when the library is expected to grow.
- Database layer: Keep it on SSD — Use the hard-drive pool for originals and bulk media, not as a substitute for local application storage.
