Best Storage for a Jellyfin Media Server (2026)
Storage is the number one ongoing cost of running a media server.
How Much Storage Do You Need?
| Library type | Average file size | 500 items | 1,000 items | 5,000 items |
|---|---|---|---|---|
| 1080p encodes | 4-8 GB | 2-4 TB | 4-8 TB | 20-40 TB |
| 4K encodes (HEVC) | 15-25 GB | 7-12 TB | 15-25 TB | 75-125 TB |
| 4K remuxes | 50-80 GB | 25-40 TB | 50-80 TB | 250+ TB |
| TV episodes (1080p) | 1-3 GB | 0.5-1.5 TB | 1-3 TB | 5-15 TB |
| Music (FLAC) | 300-500 MB/album | 150-250 GB | 300-500 GB | 1.5-2.5 TB |
HDD vs SSD: What Goes Where
| Storage type | Use for | Why |
|---|---|---|
| NVMe SSD | Jellyfin config, metadata, cache | Random I/O - SSD is 100x faster |
| SATA SSD | Jellyfin config (budget option) | Still much faster than HDD |
| HDD (7200 RPM) | Media files | Sequential reads - HDD is fine |
The golden rule: SSD for config, HDD for media.

| Drive | Capacity | RPM | Warranty | Price/TB | Best for |
|---|---|---|---|---|---|
| WD Red Plus | 4-14 TB | 5400/7200 | 3 years | ~$18/TB | Synology/QNAP NAS |
| Seagate IronWolf | 4-20 TB | 5400/7200 | 3 years | ~$17/TB | Multi-bay NAS |
| Toshiba N300 | 4-18 TB | 7200 | 3 years | ~$15/TB | Best value |
| WD Red Pro | 4-22 TB | 7200 | 5 years | ~$22/TB | Heavy workloads |
Shucking External Drives
The cheapest way to get large drives: buy WD Elements or Easystore external drives on sale and remove the drive from the enclosure.

RAID: Do You Need It?
| Setup | Protection | Usable capacity | Best for |
|---|---|---|---|
| No RAID (single drive) | None | 100% | Budget, replaceable content |
| RAID 1 (mirror) | 1 drive failure | 50% | Small NAS, critical data |
| RAID 5 (parity) | 1 drive failure | (N-1) drives | 3+ bay NAS |
| Unraid (parity) | 1-2 drive failures | (N-1 or N-2) drives | Flexible, mixed drives |
| ZFS RAIDZ1 | 1 drive failure | (N-1) drives | TrueNAS, data integrity |
For media that can be re-downloaded: RAID is optional. For irreplaceable content (home videos, photos): RAID or regular backups are essential.
Storage Planning Tips
- Start with 1-2 large drives, expand later
- Keep 20% free space for performance and future growth
- Use SSD for Jellyfin config - the single biggest performance improvement
- Consider Trickplay storage: 50-100 GB for large libraries
- Budget $15-20/TB for NAS drives in 2026

Great breakdown of the storage options for Jellyfin servers. I especially liked the explanation of when to use HDDs versus SSDs because many people overlook that balance. For anyone managing larger media libraries or multiple users, enterprise solid state drives can also be worth considering for metadata, cache, and other high I/O tasks while keeping bulk media on HDDs. Thanks for sharing such a practical and easy to understand guide.
