WD Red Plus WD60EFPX (6 TB) vs Seagate IronWolf ST8000VN004 (8 TB)
Compare a 6 TB 5400 rpm drive with an 8 TB 7200 rpm drive that share a 180 TB/year workload rating and 3-year warranty. The OEM-package question on the Seagate listing is covered.
The decision in brief
How the options differ
Both are 3.5-inch CMR SATA drives with 256 MB cache, a published 180 TB/year workload rating and a 3-year limited warranty. The WD60EFPX is 6 TB at 5400 rpm with a 180 MB/s maximum transfer and 750 g weight; the ST8000VN004 is 8 TB at 7200 rpm with a 210 MB/s maximum and 720 g. The Seagate US seller identifies an OEM package, so warranty eligibility needs a serial-number check. No exact NAS pairing was verified for either.

The buying guide
Package and specification details
Compare capacity and rotational speed as separate choices
The WD60EFPX offers 6 TB at 5400 rpm; the ST8000VN004 offers 8 TB at 7200 rpm. Manufacturer maximum transfer rates are 180 MB/s and 210 MB/s, which are exact-part maxima rather than measured NAS or network results. Decide how much capacity you need per bay before weighing the speed figures.
Both are CMR drives with 256 MB cache, a 180 TB/year workload rating and a 3-year limited warranty. Their weights are 750 g and 720 g. These shared ratings do not establish compatibility with a particular NAS model, operating-system version or drive firmware; no pairing was verified in this review.
The WD selection is a new single internal WD60EFPX, not recertified, used, a multi-pack or an enclosure. The Seagate selection is a new single ST8000VN004 from a US seller that identifies an OEM package; verify the serial-number warranty eligibility, because the July 2022 EMEA datasheet establishes hardware facts rather than a current US sales package.
No pairing or mixed-drive result was verified in this category review. Check the NAS maker's compatibility list for each exact part, capacity and firmware before combining drives.
These manufacturer specifications do not establish measured performance, noise, long-term reliability or running cost. We have not independently tested these products. Check current prices, stock and operating-space instructions with the seller and manufacturer.
Select the exact part number and capacity. A different suffix, condition or seller can change the hardware and warranty scope.
No enclosure, drive-pair compatibility result, current price or available-stock claim is included. Confirm any cables or mounting accessories with the seller.

Nominal capacity
Manufacturer capacity of the exact drive model.
Formatting, storage layout and system overhead reduce usable capacity; a mirror does not add both drive capacities.
