Overview

Syncing an Ethereum node is largely reliant on IOPS, I/O Per Second. Budget SSDs will struggle to an extent, and some won't be able to sync at all.

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

For size, 4TB comes recommended as of mid 2024. The smaller 2TB drive should last an Ethereum full node until early 2025 or thereabouts, with crystal ball uncertainty.

High-level, QLC and DRAMless are far slower than "mainstream" SSDs. QLC has lower endurance as well. Any savings will be gone when the drive fails early and needs to be replaced.

Hacky syntax highlighting in git diff

Normally git diff would color additions green and deletions red. This is cool, but it would be even cooler if it adds syntax highlighting to those lines. This is a git pager that does so.

It parses the diff output and picks up the SHAs of files with additions and deletions. It uses [CodeRay][coderay] to highlight each file and then it extracts the lines that are shown in the diff. It then uses [term/ansicolor][color] to make a gradient from the CodeRay color and the diff color (red for deletion, green for addition) and uses it to replace the original.

I tried using rugged instead of shelling out to git show – it was faster overall, but it did incur a noticeable start up time.
