8TB external hard drives: the value size for desktop storage

8TB external desktop drives — WD Elements Desktop, Seagate Expansion Desktop, One Touch Hub — often deliver the best £/TB of any plug-and-play drive, because they use the same 3.5" platters as internal 8TB drives. The table above ranks every 8TB external hard drive by real cost per terabyte.

  • Desktop 8TB HDD: the sweet spot for media collections, whole-PC backups and console libraries.
  • Shuckable: many buyers use these enclosures as a cheap source of bare drives for a NAS — check the current £/TB against 8TB internal drives first, as the gap changes week to week.

Need more? Larger externals exist at 10–24TB — browse all external drives and sort by £/TB.

Frequently asked questions

How does disks.co.uk rank 8TB external drives?

We rank every 8TB external drives by real cost per terabyte (£/TB) — the live Amazon.co.uk price divided by capacity — so the best value appears at the top. Prices refresh several times a day from Keepa, with 24-hour movement and all-time-low flags.

What is the cheapest 8TB external drives option right now?

The top of the table above is the cheapest of the 8TB external drives by £/TB today. Desktop (mains-powered) external hard drives are usually the cheapest per terabyte; portable bus-powered drives and external SSDs cost more but need no power cable and survive being carried around.

Should I buy an external hard drive or an external SSD?

For backups and media a hard drive gives far more terabytes per pound. Choose an external SSD if you will work directly off the drive (video editing, games), need shock resistance, or want it fast and pocketable — see SSD vs HDD.

Is an internal drive cheaper than an external one at this size?

Often, yes — an external enclosure adds cost. If you can fit a drive inside a PC or NAS, compare the internal listings on the full capacity page before paying for the USB case. If you need plug-and-play on a laptop, Mac or console, external is the right choice.
