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:
