Live HDD Listings Behind the Capacity Dashboard

The listing table remains available below the capacity summaries for product-level filtering and sorting.

Market Value compares a listing with current peers in the same use class, interface, condition, and capacity band. Historical Value compares it only with its own stored price record. The two columns can disagree and both be right: Market Value asks whether a listing is cheap next to comparable drives on sale today, Historical Value asks whether it is cheap next to its own past. A small drive can be Expensive per TB against its peers and still be at the lowest price it has ever had. See the Good Price guide for broader market context.

What capacity pricing shows

Capacity-level summaries make the market easier to read than a long product list alone. If 18TB and 20TB drives cluster tightly but 22TB is elevated, a buyer with spare bays may choose the lower capacity and save money.

The cheapest drive in a capacity band is not always the best purchase. Condition, interface, and historical context still need to match the intended deployment.

Why median price matters

The median price keeps one unusually cheap or expensive listing from defining the whole capacity band. It is a useful signal for procurement planning and replacement-drive budgeting.

The best $/TB column shows the current floor, while the Good Price column highlights whether any listing has a favorable value signal.

Avoiding capacity-page overlap

This page is the market comparison layer. Dedicated capacity pages remain the place to browse all known products for a specific drive size.

That keeps a 16TB buyer from needing to compare every HDD size, while still giving market-level context before choosing a final capacity.

FAQs

Why does a capacity with live stock not always link to a capacity page?

DatacenterDisk only links to capacity URLs that already exist. Live inventory can include capacities that do not yet have dedicated pages.

Is median price or best $/TB more important?

Best $/TB shows the current floor. Median price is better for understanding the typical current cost of that capacity band.

Methodology

DatacenterDisk includes current in-stock HDD listings with valid positive prices, valid positive capacity, and price-per-TB data. Out-of-stock listings and broken zero-dollar prices are excluded from current rankings.

Good Price is calculated once in the shared pricing utility from current in-stock listings and stored DatacenterDisk price records. Historical Value compares a listing only with its own stored price record for that exact drive and condition. GREAT PRICE means today's price is within 3% of the lowest we have recorded for it, or at least 15% below its own 30- or 90-day average; GOOD PRICE, within 7% of that low or at least 7% below its 30-day average; HIGH PRICE, more than 7% above its own 30-day average; FAIR PRICE otherwise. It reads In progress when we hold fewer than 7 days of records, or when the price has never moved more than 3% across its record - an unchanged price is neither a low nor a high, so it gets no verdict.

Market Value requires at least three relevant current peers and compares price per TB within matching use class, interface, condition, and capacity band. When that peer set is too small, the row shows a progress indicator instead of a market-value label.
