Write down the exact drive and destination
Begin with the full manufacturer part number and the exact NAS, recorder, server or external connection being used. Similar family names can describe different interfaces, capacities, sectors or regional retail packages. Check the selected offer rather than transferring specifications from another capacity. Read the host documentation for supported drives and installation procedures. The current listing title is useful identification evidence, but a seller compatibility claim is not a test performed by DatacenterDisk. Keep the model, condition, seller and proposed destination together while comparing the shortlist.
Separate interfaces and complete external devices
A SATA HDD and a SAS HDD can look similar while requiring different host connections. Confirm the supported protocol, power connection and physical mounting before buying an adapter or controller. An external USB HDD is a complete device with an enclosure and bridge; its price includes different components from a bare internal drive. Read the supplied power adapter, regional plug and cable details. Do not assume a USB enclosure accepts a SAS drive or that an external product contains a particular internal model unless the manufacturer documents that configuration.
Calculate the full set of drives
List how many drives the system actually needs, the capacity of each and the proposed storage layout. Raw purchased capacity differs from available space after redundancy, formatting and other system requirements. Compare equal drive counts and conditions, then include replacement trays, supported cables or adapters and a separate backup. A price per TB helps compare capacity cost, but does not measure performance, suitability or reliability. For an expansion, check how the exact software handles the new capacity and whether temporary backup space is needed during the change.
Match recording and workload requirements
For surveillance, choose capacity from your camera count, recording settings, schedule and required retention period. Check the recorder model, supported drive size and manufacturer installation advice. For a NAS or server, read the relevant drive and workload requirements instead of assuming that every large HDD has identical behavior. Vendor endurance and performance statements apply to specific models and are not our measurements. This page does not calculate a guaranteed number of recording days from capacity alone, because changing bitrate, activity and recording mode changes the storage requirement.
Keep condition and warranty attached to the price
New, used, renewed and manufacturer-recertified descriptions need separate checks. Read who provides the warranty, what the actual seller promises and which returns procedure applies to this offer. A title containing a familiar drive family does not establish a manufacturer refurbishment program. Compare like-for-like conditions and retain the full part number shown at purchase. A smaller current price can suit a planned backup or spare-drive purchase, but condition and support still matter when assessing the complete storage budget and expected service arrangements.
Plan migration and recovery before checkout
An additional drive is useful only when you can install it and restore the data you need. Check available bays, mounting hardware, supported array expansion and the sequence recommended by the system manufacturer. Keep an independent backup before replacing disks or changing storage modes. Consider how a failed enclosure, controller or recorder would be replaced and how important files would be recovered. The offers below provide current prices and configuration evidence; they do not certify a recovery plan or promise that a drive will work in every system carrying the same brand.
Compare Purple and SkyHawk against the recorder requirements
Compare the complete WD Purple, Purple Pro, Seagate SkyHawk and SkyHawk AI model numbers with the recorder documentation. A Pro or AI suffix does not certify a particular camera-analysis feature of the whole installation. Check capacity limits, drive count, interface and the requirements of the exact firmware. Retention depends on your recording settings. Include any required mounting parts and another copy of important events, then compare equal capacities and conditions using current local prices.
Model-specific manufacturer checks
Check the exact model and hardware revision. These manufacturer references support your purchase checks; they do not establish compatibility for every offer on this page.

How DatacenterDisk Compares UK Prices
Prices come from the Amazon Creators API for Amazon.co.uk through the existing UK refresh service. We do not convert US or German prices to pounds or carry discounts across marketplaces. Each row shows when its price was last checked. Prices and availability can change after that check; the price on Amazon.co.uk at checkout applies.
A price drop needs at least seven prior daily observations of the same product in the same condition, with the current price at least five per cent below their average. The comparison uses available days in the previous 30 days and excludes today. A short record is not a complete 30-day average. Newly discovered products first appear in the regular table. Historical prices and per-listing discount percentages are not displayed.
Price per TB divides the current offer price by the recorded capacity. It does not measure reliability, performance or suitability. Mini PCs, UPS units, docks, empty enclosures and networking parts have no useful storage cost per TB, so a dash appears instead. Condition stays attached to the offer: used stock is not presented as new, and a low price does not establish the warranty or included accessories.
What to Check Before Buying
Start with the exact part number. Check the interface, form factor and requirements of the system receiving the part. Compare new and used stock separately, then read the seller, return terms and warranty on the actual offer. We do not test these products ourselves or confirm compatibility from a price or listing title.
Use the price-per-TB comparison for the ongoing price overview, and read about refurbished enterprise drives before weighing used stock against a new drive. Offers and seller names come from the Amazon listing; Amazon.co.uk is the only merchant priced in this UK section.
