Buying a hard disk drive (HDD) in the UK

A traditional hard disk drive remains the cheapest way to buy storage by a wide margin — a spinning platter costs a fraction per terabyte of an equivalent SSD. The table above ranks every HDD by real cost per terabyte, live from Amazon.co.uk.

  • Desktop 3.5" internal: the best £/TB on the site, especially from 8TB upward — ideal for bulk storage, backups and media servers.
  • NAS-rated (WD Red, Seagate IronWolf, Toshiba N300): built for 24/7 always-on use and RAID — avoid SMR models here (why it matters).
  • Laptop 2.5" internal: lower capacity but fits older and budget laptops that don't take an SSD upgrade well.
  • External: the same drives in a plug-and-play USB enclosure.

If speed matters more than capacity for part of your setup, see SSD vs HDD — many buyers pair a small SSD for the system with a cheap large HDD for everything else.
