I initially found this tool when someone shared a link on Reddit. It's a handy way to compare storage options available on Amazon. I use it whenever I need to add or upgrade hard drives or SSDs.

When looking for a new hard drive, I typically use the following filters:

  • Data Source: amazon.com
  • Condition: New
  • Rotational: Internal 3.5"
  • All other checkboxes unselected

Then, I go down the list looking for the least expensive hard drive (in $/TB) with the required capacity and a 3+ year warranty.

This makes it easy to quickly find the best deal without having to spend hours comparing individual listings on Amazon.
