Erigon Hardware Requirements: Disk Type and Size, RAM, and CPU for Node Types

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 nodes 8–16 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 sync 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.

Please note that these figures are from September 2025, and the blockchain data size is continuously increasing.

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
