Append this to your ~/.zshrc file.

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 or 2TB come recommended as of mid 2024. A 2TB drive should last an Ethereum full node until late 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.

You may have experienced when dual booting that you need to re-pair your bluetooth devices (ie., Headphones, mouse, keyboard, etc) this usually happens because you have already paired the device with another operating system using the same bluetooth adapter when dual booting (either Linux or Windows).
Some devices cannot handle multiple pairings associated with the same MAC address (ie., bluetooth adapter). As per suggested on the ArchWiki you can fix this by re-pairing the device each time, but there's actually another solution to not do so each time you choose to use your device on a different OS.
Easy, just pair the device on a OS and copy the bluetooth keys generated to the other OS so our device doesn't notice the difference.
