Best-Selling Internal Hard Drives of 2019
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.
The top 100 internal hard drives on Amazon UK in 2019, 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 2019, or every hard drive of 2019.
Internal and external are Amazon’s own classification, not our guess — every drive is filed under one or the other.
