Best-Selling Internal Hard Drives of All Time
The 3.5in and 2.5in drives that go inside a desktop, a NAS or a games console — bought by the people doing the upgrading themselves.
Ranked across every year each drive charted between 2016 and 2026, weighted by how deep that year's chart ran — so both peak position and longevity count. Pick a year above, or see every hard drive of 2026.
Internal and external are Amazon’s own classification, not our guess — every drive is filed under one or the other.
