Syncing an Ethereum node is largely reliant on latency and IOPS, I/O Per Second, 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 proxy of / predictor for latency. Measuring latency directly is arguably better.
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 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 2TB drive should last an Ethereum full node until at least sometime 2026, with [pre-merge history expiry](http
I was looking after a Dell PowerEdge R420 server with a hardware RAID card in it, a PERC8 H710P Mini. Connected to this were two WD Blue 3D NAND SATA SSDs in RAID-1, that were handling a write-intensive database: Geth, in this case.
After 11 months of running without problems, I had reason to "resync" Geth, and the server could not keep up with the required IOPS.
Symptoms were Database compacting, degraded performance messages for hours, without recovery, and read/write latency in excess of 20/70ms,
as measured by sudo iostat -mdx and its r_await and w_await data.
The cause of this was that the RAID controller does not support TRIM on the SSD, and the SSD's performance degraded over time because of it.

Below are a list of System Preference pane URLs and paths that can be accessed with scripting to assist users with enabling macOS security settings without having to walk them through launching System Preferences, finding panes, and scrolling to settings. Not all panes have an accessible anchor and some are OS specific.
To find the Pane ID of a specific pane, open the System Preferences app and select the desired Preference Pane. With the pane selected, open the ScriptEditor.app and run the following script to copy the current Pane ID to your clipboard and display any available anchors:
tell application "System Preferences"
set CurrentPane to the id of the current pane
set the clipboard to CurrentPane| [Install] | |
