5TB external hard drives: the biggest portables
5TB is the largest capacity you'll find in a bus-powered portable hard drive — WD My Passport and Seagate Portable both top out here — which makes 5TB external a popular choice for anyone who wants maximum storage without a power cable. The table above ranks every 5TB external drive by real £/TB.
- Portable 5TB HDD: the whole point of this size — five terabytes that fits in a bag and runs off USB.
- Desktop 5TB: uncommon; desktop externals jump from 4TB to 6TB and 8TB.
If it will sit on a desk anyway, check whether a 6TB desktop external is cheaper per terabyte today. All 5TB drives are listed on the capacity page.
Frequently asked questions
How does disks.co.uk rank 5TB external drives?
We rank every 5TB 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 5TB external drives option right now?
The top of the table above is the cheapest of the 5TB 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.
