The top 100 internal hard drives on Amazon UK in 2025, ranked by average sales rank across the year — so a drive that sold steadily beats one that spiked for a week. See the all-time internal hard drives chart, the other side of the split at external drives in 2025, or every hard drive of 2025.

Internal and external are Amazon’s own classification, not our guess — every drive is filed under one or the other.
