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.

To recover deleted files, act quickly. When a file is deleted it isn't immediately erased — it's marked as available space. But new files can overwrite it. The sooner you try recovery, the better.
Recuva is the best free recovery tool for Windows. Download it from Piriform's website, install it, and run a deep scan on the drive where the file was. It will show recoverable files — save recovered files to a different drive than the one you're scanning.
On Mac, check the Trash first. If it's not there, Time Machine is your best bet if you had it enabled. System Preferences > Time Machine. If not, PhotoRec is a free cross-platform recovery tool.
For accidentally deleted cloud files (Google Drive, Dropbox, OneDrive), check the trash within the web interface. Cloud services typically retain deleted files for 30 days.
If these fail and the file is critical, professional recovery services exist but cost several hundred pounds/dollars.
