About ListofDisks
A drive price tracker you can actually trust. ListofDisks turns messy retail listings into a clean, comparable view of the hard drive and SSD market. We match listings to specific drive models, score sellers by reliability, and track prices over time so when something looks like a deal, there is data behind it.
How it works
We focus on data quality first so comparisons are meaningful.
Retail listings are matched to real models
Listings from retailers are collected and matched to specific drive models so you can compare like for like.
Sellers are scored for reliability
Seller type, condition, and rating signals help prevent unreliable listings from dominating the results.
Prices are tracked over time
We maintain 90-day pricing history so you can tell the difference between real deals and short-lived noise.
What we believe in
Accuracy, fair comparison, and transparent history.
Accuracy first
We do not rely on listing titles alone. If we are not confident a listing matches the right drive model, we hold it back.
Fair comparison
Retailer-direct offers and marketplace sellers are treated differently so ranking stays trustworthy.
History that does not lie
Historical pricing is preserved and smoothed with rolling medians so one-off spikes do not mislead buyers.
What we track
The data points buyers actually need.
We track price and $/TB, stock status, seller details, condition, and key drive specs such as warranty, RPM, form factor, and CMR/SMR when available.
We keep real capacities like 1.92TB and 3.84TB as-is. The interface groups them for browsing, but the underlying data stays precise.
Why this is hard
Retail data looks clean on the surface, but it is messy in practice.
Capacity can be ambiguous
Capacity can be buried in specs or mixed with unrelated numbers. We parse from multiple sources and score confidence.
The same model appears differently everywhere
Titles, URLs, and model formatting vary by retailer, so matching equivalent products takes real normalization work.
Marketplace offers change quickly
Seller quality, condition, and buy-box behavior can shift throughout the day.
History needs auditability
We fix data issues going forward with an audit trail rather than silently rewriting historical records.
