Disk Prices Tool is a free, web-based storage price comparison tool that lets you browse, filter, and sort hundreds of real Amazon listings for HDDs, SSDs, and NVMe drives by price per terabyte ($/TB).
Disk Prices Tool is a searchable database of hard drives and solid-state drives from Amazon, normalized by $/TB and $/GB so you can compare a 4 TB HDD against an 18 TB enterprise drive on equal footing. It ingests listing attributes (capacity, interface, form factor, RPM, recording type, warranty) and organizes them into a customizable table. The tool is built by the site operator and is free to use with no account required.
Key Features
- $/TB and $/GB columns — Raw price tags are misleading; these derived metrics show the true cost per terabyte or gigabyte across any capacity.
- Live search — Type any keyword (brand, model, interface, RPM) and the table filters in real time without page reloads.
- Advanced parameter filters — Stack conditions like media type (HDD/SSD/NVMe), recording type (CMR/SMR), capacity range, condition (new/used/renewed), seller rating, and more.
- Customizable columns — Show only the specs you care about: RPM, cache, sequential read/write, IOPS, TBW, MTBF, warranty, etc.
- Saved groups & share links — Save filtered results or hand-picked rows as a named group and share the link with others.
- Community editing — Any user can edit a cell value (e.g., wrong RPM) for immediate personal view; approved edits become visible to all.
Who is it for?
- Home NAS builders — Filter by CMR recording type and capacity over 8 TB to find drives suitable for RAID arrays, then sort by $/TB for best value.
- PC gamers — Filter by NVMe interface and sequential read speed over 5,000 MB/s to find high-performance drives for game loads.
- IT buyers sourcing used enterprise disks — Filter by condition (used/renewed) and interface (SAS) to compare $/TB across refurbished enterprise drives for lab deployment.
- Find the cheapest terabyte of storage today — Sort ascending by $/TB to see which listing offers the lowest cost per terabyte across all capacities.
- Compare brand pricing — Use the brand filter to compare Seagate vs. Western Digital vs. Toshiba average $/TB at a given capacity.
- Budget for a petabyte — Find the current lowest $/TB among enterprise HDDs and multiply by 1,000 to estimate raw disk cost for a petabyte.
Product data is collected from Amazon US listings for internal and external storage devices. Automated ingestion pulls listing details; critical fields like capacity, media type, and CMR/SMR are manually verified. Community edits supplement the data. Prices are monitored regularly, and new products are added as they appear on Amazon.
Pros and cons
