Overview

Syncing an Ethereum node is largely reliant on latency of the storage. Budget SSDs will struggle to an extent, and some won't be able to sync at all. IOPS can roughly be used as a proxy of / predictor for latency. Measuring latency directly is best.

This document aims to snapshot some known good and known bad models.

The drive lists are ordered by interface and then by capacity and alphabetically by vendor name, not by preference. The lists are not exhaustive at all. @mwpastore linked a filterable spreadsheet (legacy sheet) in comments that has a far greater variety of drives and their characteristics. Filter it by DRAM yes, NAND Type TLC, Form Factor M.2, and desired capacity.

For size, 4TB is a conservative choice which also supports a Fusaka "supernode". The smaller 2T

	// simplevm.c: demonstrates Hypervisor.Framework usage in Apple Silicon
	// Based on the work by @zhuowei
	// @imbushuo - Nov 2020

	// To build:
	// Prepare the entitlement with BOTH com.apple.security.hypervisor and com.apple.vm.networking WHEN SIP IS OFF
	// Prepare the entitlement com.apple.security.hypervisor and NO com.apple.vm.networking WHEN SIP IS ON
	// ^ Per @never_released, tested on 11.0.1, idk why
	// clang -o simplevm -O2 -framework Hypervisor -mmacosx-version-min=11.0 simplevm.c
