WD Purple 8TB: Three Part Numbers, Two Datasheets and Amazon.co.uk Prices

WD Purple 8TB datasheet: two 8TB models on the April 2019 sheet

WD's April 2019 WD Purple sheet lists nine model numbers, and two of them are 8TB: WD82PURZ and WD81PURZ. They are different drives with different ratings, which is why an 8TB WD Purple listing needs its part number read before anything else.

WD says each WD Purple drive is optimised for up to 64 cameras, and its 180TB rating covers the AllFrame 4K configurations from 1TB to 8TB, WD81PURZ among them. WD82PURZ is the exception at this size, with double that rating.

The 8TB WD Purple Pro: WD8002PURP

WD's July 2025 Purple Pro sheet adds a third 8TB drive, WD8002PURP, listed beside WD142PURP, WD122PURP and WD102PURP. WD states CMR recording for all four and rates Purple Pro at up to 550TB a year with a five-year limited warranty.

Against the next size up, the 8TB Pro has half the cache but is quieter at idle on WD's figures. Both are air-filled; on the same sheet only the 14TB, WD142PURP, is helium among the four smaller models.

WD Purple 8TB price on Amazon.co.uk

In all, the table draws on 3 listings in stock. The table shows 3 listings, in pounds sterling inc VAT, and the lowest price per terabyte among them is £46.25/TB. 8TB WD Purple listings on Amazon.co.uk have carried part numbers including WD84PURZ and WD81PURZ for the standard line and WD8002PURP and WD8001PURP for Purple Pro; a row appears in the table only while its offer is in stock.

Of those, WD81PURZ and WD8002PURP are on WD sheets we hold. WD8001PURP is not on the July 2025 sheet, which lists WD8002PURP, so the Pro figures above do not attach to it.

WD84PURZ: the 8TB WD Purple on neither sheet

WD84PURZ is not one of the nine models on the April 2019 sheet, and no later WD Purple sheet is in our sources: the address WD uses for its WD Purple data sheet served the 2019 file when we read it on 9 November 2026. We therefore print no workload rating, speed class or warranty for WD84PURZ from a WD document, and you should not assume it matches either 8TB model on the 2019 sheet.

Hikvision's drive list, edition v20260515, does name it. WD84PURZ-85B4HY0 appears as an 8TB surveillance entry in several series tables, with rows dated 23 February 2021 in some and 8 February 2021 in others, and rows for WD84PURZ without the suffix carry 18 July 2024. That is a recorder maker's listing for its own series tables, not a WD specification.

If a stated rating matters to your system, the 8TB drives here with a full WD sheet behind them are WD8002PURP and WD81PURZ. The CCTV storage calculator works out how much your recorder writes in a year, which tells you which rating you need.

WD Purple 8TB warranty

WD's April 2019 sheet includes a three-year limited warranty with every WD Purple it lists, so WD82PURZ and WD81PURZ carry three years on paper. WD's July 2025 sheet gives Purple Pro, WD8002PURP included, a five-year limited warranty. For WD84PURZ we hold no WD document that states a warranty, and we have not read WD's regional warranty page.

A maker's warranty is separate from what a particular Amazon.co.uk offer carries, and a used offer may differ, so check the listing before you rely on it.

Other 8TB surveillance hard drives on Seagate's sheets

Seagate's SkyHawk AI and SkyHawk sheets each list one 8TB model. The DS1960.15C SkyHawk AI sheet lists ST8000VE001 beside the 10TB ST10000VE001. The DS2118.1 SkyHawk sheet puts ST8000VX010 first in its standard table, ahead of ST6000VX009, ST4000VX016, ST3000VX015 and ST2000VX017. Seagate SkyHawk has both lines in live tables, and 8TB enterprise hard drives cover the data centre drives at the same capacity.
