Hardware Requirements
Overview
A locally mounted SSD (Solid-State Drive) or NVMe (Non-Volatile Memory Express) disk is essential for optimal performance. Avoid Hard Disk Drives (HDD), as they can cause Erigon to lag behind the blockchain tip, albeit not fall behind.
| Component | Recommendation | Notes |
|---|---|---|
| Disk Type | Use high-end NVMe SSDs. | Avoid HDDs.SSD performance may degrade when nearing full capacity. |
| Disk Configuration | RAID 0 for multiple disks (Speed) | High-Speed Option: RAID 0 provides maximum speed but no redundancy (data loss risk).ZFS filesystems may be considered for Archive nodes for their data integrity features, but complex RAID-Z setups are generally not recommended. |
| RAM | Adequate memory is crucial | Reduces bottlenecks during sync and improves performance under load. |
| CPU | 4–8 cores for Full nodes8–16 cores for Archive nodes | More cores are generally better for intense sync and query operations. |
| Linux | Kernel version > v4 | A modern Linux distribution is required. |
Disk Size and RAM Requirements
The amount of disk space recommended and RAM you need depends on the pruning mode you want to run. Current Disk Usage values listed below are obtained using the standard Erigon + Caplin configuration, with the sole exception of the --prune.mode flag.
- Ethereum mainnet
- Gnosis Chain
- Sepolia
- Hoodi
- Chiado

Bandwidth Requirements
Your internet bandwidth is also an important factor, particularly for sync speed and validator performance.
| Node Type | Bandwidth (Required) | Bandwidth (Recommended) |
|---|---|---|
| Staking/Mining | 10 Mbps | 50 Mbps |
| Non-Staking | 5 Mbps | 25 Mbps |
