4TB drives: a genuine sweet spot

4TB is one of the best-value capacities on the site — large enough for a serious media library or backup target, and manufactured at high enough volume that £/TB is usually competitive. The table above ranks every 4TB drive by real cost per terabyte.

4TB external: a popular size for desktop backup drives — see external drives.
4TB internal HDD: strong £/TB for bulk storage or a media server.
4TB SSD/NVMe: a large, fast drive for creative work or a big games library — compare against 2TB to see the cost of doubling up.
NAS: a common starting capacity per bay in a small home NAS.

Check 3TB and 6TB too — 4TB is usually competitive but not always the outright cheapest £/TB on the day.
