HDD Buying Guide: Get the Best Value
1. Compare Price Per GB
A $150 4TB drive ($0.037/GB) beats a $70 1TB drive ($0.07/GB) in value. Always divide price by capacity to find the real cost — that's what we do for every listing.
2. Bigger = Cheaper Per GB
Storage follows economies of scale. 4TB+ drives almost always have the lowest price per gigabyte. Buy more capacity upfront to save long-term.
3. Match RPM to Your Use Case
7200 RPM drives are faster and better for desktop use or active NAS workloads. 5400 RPM drives run cooler and quieter — ideal for bulk archival or always-on backup drives where speed is less critical.
4. Watch for Sales
Hard drive prices fluctuate. We update prices daily so you can catch the best deals. Bookmark this page and check back regularly.
