The difference between SSDs and HDDs matters a lot for everyday performance. An SSD (Solid State Drive) has no moving parts and accesses data almost instantly. An HDD (Hard Disk Drive) uses spinning magnetic platters and is much slower.
In practice, a computer with an SSD boots in under 15 seconds. The same machine with an HDD might take 1-2 minutes. Applications launch instantly on SSD versus several seconds on HDD. This difference is noticeable every single day.
HDDs are not useless though — they're much cheaper per gigabyte. A 4TB HDD costs around what a 500GB SSD costs. If you need bulk storage for videos, photos and backups, HDD makes sense.
Best setup if budget allows: a smaller SSD (256-512GB) for your operating system and main applications, and a large HDD for bulk storage. This gives you speed where it matters and capacity where you need it.
