Hardware requirements by tier
Three tiers for every workload: the minimum that works, the recommended sweet spot, and the comfortable headroom level. These are the same tiers the WisePC decision engine uses when it plans a build around your goal.
| Tier | CPU cores | RAM | Storage | GPU | VRAM | Network |
|---|---|---|---|---|---|---|
| Minimum | 2 cores | 4 GB | 1 TB (ssd) | None | — | 1 GbE |
| Recommended | 4 cores | 8 GB | 4 TB (ssd) | None | — | 1 GbE |
| Comfortable | 8 cores | 16 GB | 16 TB (hdd) | None | — | 2.5 GbE |
| Overkill | 13 cores | 26 GB | 32 TB (hdd) | None | — | 2.5 GbE |
Beyond Comfortable — 13 cores, 26 GB RAM, 32 TB (SSD): headroom you will never use for this workload alone. Put the difference into storage, backup or silence.
Recommended system shape
Derived by the decision engine from the recommended tier — the same logic that plans full builds.
Light requirements (4 threads, 8GB RAM) fit a sff prebuilt system — simpler and more efficient than building from parts.
One box or a separate machine?
Keep on the main serverLightweight always-on service — a separate system would add cost, energy and maintenance for no benefit.
Whether this workload deserves its own system or should live on the main server.
Storage arrays, priced
Five physical strategies for the recommended capacity — the same planner, drive model and reference prices as the storage planner tool.
| Strategy | Drives | Usable | Cost | Idle |
|---|---|---|---|---|
| Cheapest | 2× 4TB hdd | 4 TB · parity1 | ≈ €472 | 10 W |
| Balanced Recommended | 2× 16TB hdd | 16 TB · parity1 | ≈ €1768 | 12 W |
| Redundant | 3× 8TB hdd | 8 TB · parity2 | ≈ €1227 | 15 W |
| Expansion-friendly | 2× 20TB hdd | 20 TB · parity1 | ≈ €2000 | 14 W |
| Performance | 2× 4TB nvme | 4 TB · parity1 | ≈ €1588 | 2 W |
For a fast working tier, go all-flash — the performance strategy protects speed without the HDD rebuild pain.
Backup is not storage
The extra copy that survives drive failure, deletion and ransomware — the same engine as the backup planner.
For 4TB of irreplaceable data, go straight to the full 3-2-1 — a local NAS plus an offsite copy.
Add a second copy outside the building — cloud or a drive at a friend's house.
Use a versioning-aware tool (restic, borg, Backblaze) that keeps history.
Schedule backups automatically and monitor them.
Keep the backup on separate hardware or offsite.
What will it cost?
Market-neutral EUR bands from the reference drive model (≈ = estimated street price). Live component prices resolve on the build page for your region.
Compute (CPU, board, RAM, GPU) is not included — see the recommended build for live prices.
Growth outlook
What happens when the data keeps growing — the same engine as the growth simulator.
Storage stays within 16TB across the 3-year horizon — the architecture fits your expected growth.
Within capacity and bays — no new bay needed for 7TB.
Which tier do you need?
- Pick Minimum (2 cores, 4 GB RAM) only for a single-purpose machine on a tight budget — expect little headroom.
- Recommended (4 cores, 8 GB RAM) is the sweet spot: enough for the workload plus the usual side-services, without overspending.
- Pick Comfortable (8 cores, 16 GB RAM) when this workload shares the machine with others or will grow — you pay for headroom, not for anxiety.
- GPU rule for this workload: None.GPU rule for this workload: None (no discrete VRAM needed).
