Choosing an external hard drive or SSD

An external drive plugs straight into a USB port — no opening the case, no fitting, works with almost any PC, Mac or console. The table above ranks every external drive by real cost per terabyte, so the best value sits at the top regardless of size or brand.

  • External HDD (desktop, mains-powered): the cheapest way to add bulk storage — 4TB to 24TB+ for backups and media libraries.
  • External HDD (portable, bus-powered): smaller, no separate power cable, typically 1–5TB — ideal for carrying between machines.
  • External SSD: far faster and more shock-resistant than a hard drive, worth the premium for editing video or gaming off the drive directly.

Popular external ranges include WD My Passport and Elements, Seagate Expansion and One Touch, and LaCie's rugged and portable SSD lines. Compare against Western Digital and Seagate internal drives if you're fitting rather than plugging in, and open any listing for its full Keepa price history before buying.
