Great and less great SSDs for Ethereum nodes

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. Remy wrote a migration guide to 4TB.

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.

Proposal for a light client friendly log event search data structure

Author: Zsolt Felföldi (zsfelfoldi@ethereum.org)

Note: this is an informal write-up and the exact details of the data structure presented here might need further clarification. If there seems to be interest in this idea and no one finds any major holes in it then I want to write a proper EIP for this.

Here I attempt to solve two problems with our current bloom filter based log event search mechanism. One of them concerns both full and light clients: the bloom filter size is fixed and does not adapt to the increased number of log events per block due to increased gas limit. This leads to too many false positive matches, rendering the whole bloom filter mechanism almost ineffective. The other issue concerns light clients: even if we increase the bloom filter size, using the filters with a light client is only possible if the client syncs up the header chain. Geth light client did that until now but after the merge this practice becomes

Solution for 'ssh: connect to host github.com port 22: Connection timed out' error
$ git clone git@github.com:xxxxx/xxxx.git my-awesome-proj
Cloning into 'my-awesome-proj'...
ssh: connect to host github.com port 22: Connection timed out
fatal: Could not read from remote repository.
$ # This should also timeout
$ ssh -T git@github.com
ssh: connect to host github.com port 22: Connection timed out
$ # but this might work
