Disk Price Tool is a searchable database for comparing hard drives and solid-state drives across Amazon marketplaces. It pulls data from hundreds of listings and puts them into a single table. People building home servers or upgrading PCs use it to find the best value without manually calculating costs in a spreadsheet.
This site solves the problem of comparing drives with different capacities and technologies. A $200 drive might look expensive, but if it has 20 TB of space, the cost per unit of storage is often lower than a $90 drive. This tool does that math automatically for every listing it finds.

- Filters for recording technology such as CMR and SMR
- Technical specs including rotational speed, cache size, and NAND type
- Real-time search that updates the table as you type
