Solid State Drive / Hard Disk Drive comparison
I have older Western Digital 1 terabyte SATA hard disk drives (5 inch WD10EZEX) in some tower PCs, running ancient CENTOS Linux. Those drives will be replaced with Samsung 1 terabyte SATA solid state drives (3 inch 870 EVO) running Debian 12 Bookworm, probably upgraded to Debian 13 Trixie in late 2025.
Here's a rough comparison between the two drives:

My experience - the much faster speed of the SSD means I get more done. Debian boot-to-prompt is less than 10 seconds, shutdown is 1 second. I hope to arrange 10 second "suspend-with-reminders", so I can power down machines without interrupting workflow.
