Direct answer

NAS hard drive prices should be evaluated by capacity, family, recording method when known, warranty, and whether today's price is good for that exact NAS drive line. The lowest $/TB listing is not automatically the best NAS purchase.

Live NAS HDD Prices

Use family, capacity, condition, recording method, warranty, and Good Price filters to compare NAS-ready listings.

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.

NAS pricing is not only about capacity

In a NAS, the right drive is the one that matches the enclosure, workload, noise tolerance, warranty expectation, and rebuild plan. Price per TB is useful, but it should be read alongside the drive family and condition.

A used enterprise drive can beat a NAS drive on $/TB while still being a worse fit for a quiet home NAS. Conversely, a NAS model can be worth paying for when warranty and compatibility matter.

CMR, SMR, and unknown recording

DatacenterDisk surfaces the recording method when it is known in the product data. CMR is generally preferred for RAID and rebuild-heavy NAS workloads; SMR can be acceptable for lighter sequential storage but needs more care.

Listings with unknown recording method remain visible because availability changes constantly, but the filter lets you narrow the table when confirmed data exists.

How to choose from the table

Start with the capacity you need, then filter to the family and condition you are willing to buy. Use the Good Price badge to avoid overpaying for a familiar NAS label during temporary price spikes.

For multi-bay purchases, compare the cost of the whole set and the cost of at least one spare, not only the single-drive price.

FAQs

What is the cheapest NAS hard drive today?

The market summary and table update from live inventory. Use the NAS page filters to compare current lowest price, lowest $/TB, and Good Price status.

Should I buy used drives for a NAS?

Used drives can be cost-effective, but they increase the importance of backups, SMART checks, seller policy, and spare planning. Do not treat used and new listings as equivalent.

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.
