# 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.

## Disk Size and RAM Requirements

The amount of disk space recommended and RAM you need depends on the [sync mode](https://github.com/erigontech/erigon/blob/main/docs/gitbook/src/get-started/fundamentals/sync-modes.md) you want to run. **Current Disk Usage** values listed below are obtained using the standard Erigon + [Caplin](https://github.com/erigontech/erigon/blob/main/docs/gitbook/src/get-started/fundamentals/caplin.md) configuration, with the sole exception of the `--prune.mode` flag.

## 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                 |
